Know the weather proverb by fog.

Spring foggy day, summer foggy rain, autumn foggy cool wind, winter foggy snow.

The fog is not set, and the drizzle is endless; When the fog rises, it closes, and the rising sun can be found.

Spring foggy day, summer foggy rain; Autumn fog and cool wind, winter fog and snow.

It was foggy in the morning and sunny all day.

Ten fogs and nine sunny days.

One fog, three eyes.

The fog poisoned the sun.

Get up early in the morning, fog and dew, break the gourd at noon. Clouds cover the sky at night and wear shoes in the morning; It's foggy in the morning. Just wash your clothes and pants.

Proverbs about clouds

Clouds are dense drops of water or ice suspended in the sky. It can rain or snow from the clouds. Anyone who has experience in weather changes knows that whatever clouds hang in the sky is what the weather is. Therefore, clouds are the appearance of weather, and the shape of sky clouds can show the dynamics of weather changes in a short time. Cloud is a phenomenon that can be directly seen by the naked eye, so there are the most proverbs about it, which is more in line with scientific principles.

Fog is also a dense water drop or ice drop suspended in the sky. As far as existing entities are concerned, there is no difference between fog and cloud. But judging from the reasons for their formation and the environment in which they appear, they are two different things. The bottom of the fog layer is close to the ground, so it can be seen that the foggy air layer does not move upward, and the cooling process necessary for water vapor condensation is carried out in the stable air layer on the ground. This means that in foggy weather, the atmosphere is stable, and the atmospheric instability of clouds is just the opposite. The weather that finally evolved was just the opposite. Cloudy weather is mainly rainy, and foggy weather is mainly sunny. Similarly, fog is a phenomenon visible to the naked eye, so there are many proverbs about fog.

It's foggy in the morning and sunny all day. (Luanxian County, Hebei Province)

* Ten fogs and nine sunny days. (Shangqiu, Henan)

* One fog and three eyes. (Weixian County, Hebei Province)

The fog poisoned the sun. (Changzhou, Jiangsu)

* Get up early and get foggy, and break the gourd at noon. (Cang County, Hebei Province)

The fog in the morning is the product of radiation and heat dissipation on the ground last night: due to the clear sky, the heat on the ground spreads smoothly all night, and the water vapor in the ground air becomes saturated and condenses into fog drops. You can see that the weather will clear up first, and then it will be foggy. Morning is the lowest temperature between day and night. Because the temperature is coldest, the fog is thickest at this time. In addition, as soon as the sun comes out, some oxygen in the air becomes ozone because ultraviolet rays shine on it. This small amount of ozone will make a lot of dust (mostly combustion products, such as carbon dioxide, sulfur dioxide and so on) in the air. ) enhance your water absorption ability. So the fog curtain suddenly became thicker in the morning. But the sun rises, the heat intensifies, the ground becomes too hot, and the air in the lower layer will rise, so the fog drops will dissipate. In this way, the fog in the morning temporarily thickens, which is also the result of clear skies and sunny weather in Wan Li.

* Clouds cover the sky at night and wear shoes in the morning; It's foggy in the morning. Just wash your clothes and pants. (Hunan)

Clouds cover the sky at night, and there is no dew and frost on the ground in the morning. So don't wear rain boots when you go out in the morning. This is because the clouds in the sky can protect the ground from heat dissipation. If there are clouds at night, it won't be very cold in the morning, and the water vapor sticking to the ground won't condense into dew or frost, so the ground is clean.

It's foggy all over the ground in the morning, and the weather is good. Just wash your clothes and pants. Fog is the product of sunny days. If there is fog, it must be sunny.

* The fog does not exceed level 3. (Hunan)

* The fog will only last for three days, three days or eighteen days. (Hebei)

If the fog lasts for three days, there will be a strong wind. (Hu Hezhi Te)

* Where there is fog for three days, there will be heavy rain. (The Emperor's Century)

There are many kinds of fog, and the causes of all kinds of fog are also different. However, what can be called fog and can happen for three days in a row is probably low radiation fog, sea fog or tropical airflow fog.

Low-radiation fog appears in the high-pressure center of fine weather. Therefore, in foggy days, the temperature is very high during the day, which leads to low air pressure. If the weather is fine for three or four days, the local air pressure will be greatly reduced, so the airflow from other places will blow here and the weather will change.

If fog appears in the ocean airflow, it is called sea fog. Because this airflow comes from the ocean, the temperature is extremely warm and the humidity is extremely high, and then the local air pressure will gradually decrease and the weather will change.

In autumn and winter, tropical airflow often blows to the north. Because the ground is cold at this time, the air near the ground is also cold and foggy. This is called tropical airflow fog. The tropical airflow prevailed for three or four days. It must be warm and humid here, the air pressure became lower, and then the weather changed.

It's foggy in the morning and sunny at night. (Tai County, Jiangsu Province)

Early fog refers to the fog during the day. Cloudless weather, sunny, warm ground, airflow can only rise into clouds, it is impossible to stay on the ground and become fog. It's foggy during the day, but there are clouds in the sky and the sun is not there. This is a cloudy scene. Another possibility of fog during the day is the low-level clouds in the cyclone and on the warm front, which is the weather in the center of the cyclone, and of course rainy weather is just around the corner.

Night fog is fine. Night fog is equivalent to night fog and early morning fog, so it must be sunny.

* foggy days in spring, foggy days in summer; Autumn fog and cool wind, winter fog and snow. (Jiangyin, Jiangsu, Changsha, Hunan)

It's still cold in spring, and it's even colder on a clear night. The atmosphere is cold and heavy, the ground is calm, warm and light, floating on it, raising the temperature upwards. So the ground water vapor condenses into fog first, and then develops upwards; But the upper air temperature is warmer and there is less water vapor, so the development of fog is limited to the thin layer on the ground. It is only a few feet high, and the lowest is only as high as a human body. After dawn, the sun came out, because the sky is cloudless in Wan Li, the ground is hot, the fog rises and dissipates, and the sky is still strong sunshine. This is the explanation of "Spring Fog Day". But if the rising fog is prevented from rising by the warm air at high altitude, then the fog curtain will appear as a layer of clouds in the sky and the weather will be cloudy. So "the sun rises in the spring fog" is not inevitable.

In summer, the weather is hot, the days are long and the nights are short. It is impossible to cool the ground air to the point where it can condense fog in one night, so there can be no fog in summer in Mystery. If there is fog in summer, it may be because there are clouds in the sky, the lower layer is wet and thick, the sun is weak, the ground temperature is not strong, and the airflow does not move upward. This is a scene of cyclone weather. The fog you see may be a low cloud in a cyclone, so it's going to rain.

Fog in autumn and winter, like spring, is also the product of sunny days, so there are still many good weather during the day for the same reason as "spring fog". But the sunshine in autumn and winter is not as strong as that in spring. The so-called "autumn mildew and cool breeze, winter fog and snow" may be at the front of high pressure in the south, because cold air and local warm air often mix to produce fog. When the high pressure first came, the wind was quite strong and it could snow in winter. If it is in the center of high pressure, there may be a sinking westerly wind during the day.

* Clouds eat fog, and fog eats clouds. (Hohhot)

After the fog clouds, it rained; The clouds are clear and the sun is shining. Fog is more common in anticyclones, and the weather is unfathomable; Clouds that cover the sky are more common in cyclones and the weather is bad. After the fog, a big cloud came. Maybe the anticyclone has passed and the cyclone is coming. It is also possible that the sky is warm and wet, the fog is thick and clouds appear. This is the scene before the rain. On the other hand, if the clouds disappear and the fog rises, it means that the cyclone has gone, and the mysterious anticyclone weather has arrived, and it will be fine.

* When the fog goes down the mountain, the ground won't dry. (Hohhot)

* Clouds cover the bottom of the mountain, with little thunder and little rain. (Inner Mongolia Hu Hezhi Te)

* cloudy foothills, wet feet. (Yiwu, Zhejiang)

This refers to the phenomenon that the clouds on the mountain fall to the ground.

This is the cloud system in the cyclone. The farther you go to the center of low pressure, the closer you get to the rain area. So the phenomenon of low clouds indicates that it is going to rain and the ground is not dry yet.

* The fog will never stop and the rain will never stop; When the fog rises, it closes, and the rising sun can be found. (Yiwu, Zhejiang, Yuanxi, Jiangsu)

Fog usually appears on a clear night. Under normal circumstances, after sunrise, as the sun rises, the fog will slowly disperse, and there will be good weather with "the rising sun can be found". If the fog does not disperse after sunrise, it is likely that there are clouds above the fog. At this time, the fog can rise and meet the clouds, which will increase the thickness of the clouds and lead to continuous drizzle.

* Mountains are covered with rain, and rivers are covered with sunshine. (Fuling, Sichuan)

The cover on the top of the mountain is a low cloud covering the mountain. This is the scene of the rain area in the center of the cyclone, so it's going to rain. The cover of the river is low radiation fog, which is the product of sunny days and the result of cloudless days and ground heat dissipation. Therefore, it is said that "the river is facing the sun".

* Wear it at the top of the sky and hang it on all fours at dusk. (On Tian Xing)

* One day, one night, the main eye; On the contrary, it will rain. (On Tian Xing)

The meaning of "one day in the morning" is exactly the same as that of "one day in the morning", "one day in the evening" and "one day in the evening", which are all signs of sunny days.

After the sun goes down on a sunny day, the air on the ground is calm, and the air in the morning is even more silent. At this time, only when it condenses into low fog on the ground can there be no clouds. Therefore, "zenith wear" has become a guarantee of fine weather. In any mysterious weather, the sun is strong, and the ground airflow can rise to form clouds; But the four sides of the horizon are suspended and clean. This cloud is generated at the local zenith, or there may be convective thunderstorms, but it will soon disappear, so it is a sign of good weather in the future. If a storm comes in the distance, there must be thick clouds on the horizon, which can never be empty.

* fog pulls Wenzhou, and umbrellas don't have to be collected; You don't need an umbrella to pull Huangyan in fog. (Huangyan, Zhejiang)

This proverb is popular in Ningxi Town, Huangyan, Zhejiang. Wenzhou is in its southwest, and Huangyan is in its east. The fog here is actually a low cloud in a cyclone. It often moves from west to east with cyclones, so it always goes to Wenzhou first, then to Ningxi Town, and then to Huangyan County. Seeing the fog in Wenzhou in the southwest, it means that there is a cyclone coming, so there is no need to close the umbrella. On the other hand, if the cyclone has reached Huangyan in the east, or there is a storm in Huangyan, it will always move eastward again, and it is never too late to move westward. There is no need to bring an umbrella.

* Less rain and more drought. (Huhegut)

The height of the sky is actually the height of the cloud. Clouds are formed by the condensation of air currents rising from the ground, which bring water vapor to high altitude. The more water vapor in the air, the higher the air does not rise, and the clouds will condense; The clouds in the center of the cyclone are very low. The reason why there is so much rain in the cyclone area is that the air moves upward and carries a lot of water vapor. On the contrary, if the air is very dry, the updraft must rise to a very high height to form clouds. If the updraft is not strong enough, there will be no clouds at all and the sky will be higher. Therefore, the height of the sky shows that the water vapor is poor or weak, which is the case with anticyclones, so less rain and drought are the main reasons.

* Clouds are rising from the mountains, and light rain is coming. (Tongcheng, Hubei, Changshu, Jiangsu),

* The mountains are covered with tents, and the plains are full of stoves. (Huanggang, Hubei)

* When it rains, the mountains and rivers show clouds (Confucius lives in the Book of Rites)

* Clouds overflow from the top of the mountain and it will rain heavily. (Guixian, Guangxi)

* North and South wear hats and long-term workers take a nap. (Song County, Henan Province)

The above five sentences say that there are clouds on the top of the mountain, which means it will rain. There are clouds on the top of the mountain, which means the clouds are already very low. This is a scene in a tornado. The whirlwind has come, and it's going to rain. Another possibility is that a wet airflow blowing from the head is pushed up by the hillside, and it can also condense into clouds on the hillside. The air is wet and heavy, which may also be a precursor to rain.

* Clouds heading east, blowing; Clouds to the west, wind ditch overflow; Clouds flow south, long eaves flow, clouds flow north, and bricks are dried. (Linfen, Shanxi)

* clouds to the east, a gust of wind; Clouds go west, water and mud; Clouds to the south, water to the sky; The clouds went north, and it was dark. (Hebei)

* Traveling in the east, cars and horses are connected; Clouds travel to the west, horses splash mud; Clouds travel to the south, and the water in the pool rises; Traveling in the north, it is good to bask in wheat (Cui Shi's "Agricultural Proverbs" is sunny and rainy)

* Clouds and winds in the east; The clouds in the west are covered with farmers; Clouds to the south, water waves rippling; Yunbei, the turtle died by the pit. (Hunan, Zhengding, Hebei and Fugou, Henan)

East-facing clouds and strong winds; The clouds in the west have no roof; Clouds to the south, water without eaves; The clouds drifted to the north, and it was dark. (Cang County, Hebei Province)

* Clouds heading south, Black Dragon Pool; Cloud to the north, dry ink; The clouds moved westward. Master Guan is riding a horse and wearing hemp fiber. (Hebei, Han County, Henan Province)

* Clouds heading east, a gust of wind; Clouds to the west, rain; Cloud to the south, with hemp fiber; Clouds heading north are good for bask in the quilt. (Yiwu, Zhejiang, Wuxi, Jiangsu)

The meaning of the above sentence is the same, pointing out that if the clouds go from east to west or from north to south, it will rain; If the clouds are from west to east, or from south to north, the weather is fine. The cloud mentioned here is very useful if it is a low cloud in the cyclone area. If you mean the high clouds, it will be reliable in the end.

The height of the low clouds in the cyclone area is less than one kilometer, and the lowest clouds can touch the ground and appear in the form of fog. Because the winds in the cyclone area converge from four directions, the cyclone itself moves from west to east. So the wind in front of the cyclone is easterly, the wind behind it is westerly, the wind in the north is northerly, and the wind in the south is southerly. The low cloud is moved by the wind in the same layer, so we see the cloud moving from east to west, which means that this place is in front of the cyclone, and the cyclone will come to this place and it will rain tomorrow; On the contrary, if the cloud is from west to east, it means that we are behind the cyclone, the cyclone will pass and the sky will clear up. If the cloud moves from south to north, it means that we are in the south of the cyclone. Warm and humid airflow prevails here, and the gas layer is stable, so there can be no violent upward movement. The cloud is also layered, and its top can't go deep into the sky, so the temperature is still above freezing point, and there is no ice and snow on the top of the cloud, so it can't rain heavily, at most it will rain in Mao Mao; On the other hand, if the cloud faces south, it means that the dry and cold northern airflow prevails in the northern part of the cyclone. In the south, the lower floor gets warmer, resulting in the phenomenon that the upper part is cold and the lower part is warm, and the upper part is heavy and the lower part is light. So convection is the most exciting, and big clouds like mountain animals often appear. Because the cloud top is very high, the temperature is often below zero, and the cloud top is made of ice and snow, so it often rains heavily. If there is an uphill movement of the southern airflow above the northern airflow layer, the clouds will be thicker and the rain will be more violent.

There is also a saying that if the clouds are from east to west, or from north to south, it means that the wind in the upper air is easterly or northerly, which may be a precursor for the typhoon to attack the local area. Therefore, it may rain heavily.

* Clouds rise in the southeast, but it won't rain for long. (Baoding, Hebei)

* Dark clouds are in the east, and the rain is not fierce; Dark clouds are in the south, and the river turns over the pool. (Anhui Huaiyuan)

In our temperate and subtropical regions, the large-scale flow of free atmosphere is from west to east, so all kinds of disturbances in the atmosphere basically follow the movement from west to east. We see that the dark cloud is in the east or southeast. It must have followed the circulation of the atmosphere to the further east and never came back to the local area. So even if it rains here, it's already rain on its tail, and it will be over soon.

Dark clouds appear on the front between the north and south air currents. If this dark cloud has reached the south of our country, it will continue to go south with the north wind and will not go to the local area again. So the local weather was dry and the pond needed water, so it had to be turned over from the river.

* Look at the northwest black at night, and watch the wind and rain at midnight. (Yiwu, Zhejiang, Yuanxi, Jiangsu)

* Dark clouds rise at sunset and rain sounds at midnight. (Middle and lower reaches of the Yangtze River)

* When the sun goes down, dark clouds will catch up and the wind and rain will be fierce. (Guangdong)

* Dark clouds see the sun, but only for three days. (Fujian Fuqing Pingtan "Peasant Fisherman Congyan")

* Walking in the clouds at sunset, it rains after midnight. (On Tian Xing)

* Dark clouds can't wait until midnight. (Hebei)

* Dark clouds see the sun and thicken at dawn. (Southern Jiangsu)

* Dark clouds see the sun, and the Ming Dynasty is not as good as today. (On Tian Xing)

* sunset glow; If it doesn't rain, it will be very cold. (same as above)

The above sentences all say that the sun is setting and the clouds are gathering in the west. It's going to rain. After sunset, with the disappearance of sunlight, the conditions for air heating and rising disappear. Under normal weather conditions, the clouds will gradually dissipate. If there are black clouds in the west at sunset, it means that these clouds are not clouds generated by sunlight under normal circumstances, but clouds of precipitation storm system. Because any kind of rainstorm, it follows the west wind of the great cycle and travels from west to east. Now I see that the thick clouds in the west have arrived. This is a situation where a storm is coming from the west. After midnight, or at dawn, the storm will come and it will rain.

The precipitation time depends on the speed of storm migration and its internal organization. Some heavy rain areas are large, and some rain areas are small; Some people walk fast, others walk slowly. As far as cyclone-a kind of storm is concerned,1February runs the fastest, 48km per hour, and July runs the slowest, only 30km per hour. The limit speed is between 56km and13km. So it may not be reliable to say that it rains in the middle of the night or it gets thicker at dawn.

In addition, every storm does not necessarily rain, and even if it rains, it does not necessarily fall in the east. Often due to the tortuous path, the rain belt is not distributed in a straight line. In a word, the above sentences can only be said to be generally correct.

It's cloudy and rainy in the west, not only at sunset. There is also a saying that "there are dark clouds in the northwest, and thunderstorms are bound to come."

* There is no dark cloud hole tonight, and my back is hurt by the sun of the Ming Dynasty. (Changzhou, Jiangsu)

There are dark clouds on the west side of the sun, which are broken, not layered. This cloud is caused by heat convection in the west during the day and will disappear at dusk. Unlike clouds in cyclones, they are systematically spread all over the day, and it is impossible to destroy them locally. So this broken cloud is not a sign of rain in the future, but a sign of sunny weather and strong sun.

* At dusk, midnight clouds begin, and midnight rain comes. (Zhejiang righteous bird)

* two more clouds, three more open; In the middle of the night, the clouds went up and the rain came. (same as above)

These two sentences are the sight of the seaside. Clouds generated by sea surface thermal convection occur at night. This is because the change of seawater temperature is less than that of air temperature. In other words, the temperature is higher than the water temperature during the day and lower than the water temperature at night. So during the day, the atmosphere is cold and warm and relatively stable. There is fog on the sea, and there will be no clouds and rain. The atmosphere is unstable when it is cold and warm at night, and the lower air rises and develops into clouds. Therefore, the clouds on the sea at night are not signs of rainy days, and will soon disappear. However, after midnight, the difference between water temperature and air temperature decreases and approaches zero. If the cloud does not dissipate, it means that the cloud is not generated locally, but comes with a distant front or cyclone, so it will rain in the middle of the night.

* Summer clouds with black hearts and red edges. When it rains, it will hail. (Taikang, Henan)

In extremely hot summer, there is strong convection because the ground is particularly hot. Convection often causes cumulus clouds or cumulonimbus clouds to be as tall as mountains and as mighty as beasts. Cumulonimbus clouds are the mother of thunderstorms, so they are also called thunderstorm clouds. This cloud is thick in the middle and light in the periphery. At sunset, the western hills are lined with red sunshine and red all around. But the center of the cloud is thick, and the red light can't penetrate, so it presents a black heart.

The top of this cumulonimbus cloud can often be more than five kilometers above the ground, so the temperature at the top of the cloud can be as cold as MINUS 10℃, which is a combination of ice and snow. This kind of ice drops and snow crystals fall into the air when they grow up, and then meet with the updraft from the ground, blowing up the ice drops on the way down and then lifting them up. Because the sky is cold and wet, a layer of ice chips condenses around it, which increases the weight and then drops. If you encounter updraft again, add ice, and the weight will increase again. The next time this happens, the weight will increase once. When the weight increases to the point where the updraft can't blow, it will fall and become hail.

It can be seen that the cause of cumulonimbus clouds indicates that there is a strong updraft on the ground. Because of the updraft, the ice drops falling from the top of the cumulonimbus cloud may be lifted up and come back many times, so they may come from the "Xia Yun" with "black heart and red edge", that is, the cumulonimbus cloud. But if the updraft under the cumulonimbus cloud is not strong enough, hail is not inevitable. Therefore, this proverb sometimes cannot stand the test.

* There are clouds at sunrise, and it will be cloudy without rain. (Jiangsu)

* In the morning, the clouds are thick and it is raining in Mao Mao. (Jiangsu)

* When the sun rises, it will be cloudy when there is no rain. (Yiwu, Zhejiang)

* Clouds are like morning mountains, and the rain is yellow and hazy. (Guangdong)

* Dark clouds cover the morning, and the wind comes without rain. (Suzhou, Jiangsu)

* Yun Qi, Yin wins Yang. (same as above)

* When the sun comes out, it will meet clouds, and when there is no rain, it will be cloudy. (Hohhot, Inner Mongolia)

All the above is that it will be cloudy and rainy in the morning.

Whenever the mysterious weather is stable, the temperature at night and in the morning is often the coldest on the ground, and the warmer it gets in the sky, resulting in the inversion phenomenon of upper warming and lower cooling, and the gas layer is particularly stable. At this time, water vapor condensation is limited to the ground with low fog or frost dew, and there can be no clouds. On the contrary, if there are layers of clouds that spread all day in the morning, or cumulonimbus clouds like mountains and beasts, then there is only the possibility of a storm. So it's cloudy in the morning, which is a sign of a storm coming and rain in the distance.

* Cloudy in the morning, sunny in the afternoon and cloudy in the middle of the night, (Hunan)

In sunny weather, cumulus clouds are often produced by convection at lunch. This kind of Yun Qi from the local area dissipated with downward flow at dusk, so the weather cleared up immediately. However, if the clouds rise in the morning or at midnight, it is not a good weather phenomenon, and the weather is bound to get worse in the future.

* Fish scales appeared in the sky, and the lake was sunburned into a hard mountain. (Jiangsu and Huanggang, Hubei)

* There are flowers and clouds in the sky, and the sun on the ground kills people. (Huanggang, Hubei)

* The old carp covered the clouds and basked in the old monk. ("Tian Hang" winds up)

* carp in the sky, don't turn over the sun valley. (Nanjing, Yulin, wei county, Hebei)

* Tonight, the flowers are blooming, the clouds are rolling and the sun is burning. (Anhui)

In a single stable air mass, although there is no systematic disturbance, there is also a weak breeze. This kind of wind blows over the ground, and it will also stir up a chaotic vortex because of the buildings, trees and uneven terrain on the ground. This small vortex, because of its dynamic characteristics, moves to the high altitude, so it takes the water vapor on the ground to the high altitude and then condenses into clouds through adiabatic cooling. Because such condensed clouds are mostly hexagonal, they look like scales on carp and like corollas. Because the air mass generated by this cloud is stable in nature, this cloud will be destroyed when it encounters downdraft at dusk, and the weather is still in an unfathomable state.

* Dark clouds pass through the Milky Way, and rain can't escape. (Hubei)

* Black pigs cross the river, and heavy rain becomes a river. (Yiwu, Zhejiang)

* The river was covered with dark clouds and it rained cats and dogs in the middle of the night. (Guangdong)

* Dark clouds cross rivers and streams, and everyone looks at the embankment. (Guangdong)

There are clouds like sheep and pigs everywhere, and rain is coming. (Xiang Colleen Chan and other rain methods)

When the pig crossed the river, it rained that night. (Kaifeng, Henan)

A lazy dragon came out of its nest. (Weixian County, Hebei Province)

* The wind is clear and the moon is clear, and black pigs are ploughing heavily. (Fujian Fuqing Pingtan "Peasant Fisherman Congyan")

The above paragraphs have the same meaning. Rivers, streams and Jiangdu mentioned in proverbs refer to the Milky Way. The so-called river pig, lazy dragon and black cloud are river weirs, all of which are big rain clouds that flew across the sky with the strong wind at that time. This kind of rain appears on the cold front of cyclone or typhoon area, so it is a precursor of heavy rain.

Today is a fish scale day, even if it doesn't rain, it will be windy. ("Tian Wu Jia Xing" talks about clouds)

Clouds are small pieces of white, or balls, white and transparent colors, arranged in groups, and also have the shape of ripples. This cloud looks like a fish scale, but it is not thick and gray. Meteorologically, this kind of cloud is called cirrocumulus, which occurs in the precursor of cyclone. So when this cloud comes, it tells us that the cyclone will follow, so "if it doesn't rain, the wind will jump."

* Clouds meet and it's raining. (Wuxi, Jiangsu)

* There was a hook cloud in the sky, and it rained for three days and five days. (Jiangsu)

* Raindrops in kareem abdul-jabbar. (Jiangsu, Zhejiang, Hubei)

There were clouds in the sky and it rained for three days. (Guangdong)

* kareem abdul-jabbar catches clouds and groundwater hits people. (Guangdong)

* It rains cats and dogs. (Anhui)

* broom clouds, soaking people to death; Fish scale clouds, sunburned to death. (Xining, Qinghai)

The so-called "promiscuous cloud", "cloud crossing cloud", "hook cloud" and "shrimp beard cloud" all refer to hook cirrus clouds, and "broom cloud" refers to dense cirrus clouds. These clouds all appear in front of the cyclone, indicating that the high-altitude wind is strong and humid, so there are signs of rain.

* The dragon hangs over the river, and the weather is fine. (Changzhou, Jiangsu)

Commonly known as "dragon", that is, meteorological tornado. It is shaped like a funnel, hanging at the bottom of the cumulonimbus cloud. The central air pressure is extremely low, and the surrounding air rotates around the central axis. The wind is extremely strong, but the range is extremely small. Its average diameter is only a few tens of feet, and its life span is extremely short, averaging three to five hours. Because the appearance of cumulonimbus clouds is the product of sunny and hot weather, the influence of tornadoes on the weather is extremely limited in time and space, so the weather in a wide range is still in mystery. However, tornadoes can also occur under the cumulonimbus clouds of the cold front. With the influence of a wide range of cold fronts, the weather may not be "sunny".

* Not afraid of obscurity, but afraid of staring. (Cang County, Hebei Province)

Haze is a phenomenon of poor visibility in the air when the ground water vapor and dust are thick. Water vapor and dust can be concentrated on the ground, not dispersed and not rising, indicating that the airflow at that time was stable and mostly in an anticyclone state, so the weather did not change. Staring at the terrible shape of huge clouds is obviously caused by the sharp rise of airflow, so the weather is changeable.

* Aconitum wind, white-headed rain. (Jiangyin, Jiangsu, Suzhou, Jiangsu, Baoding, Hebei)

Aconitum bald head is a common name for dark clouds and white clouds. The reason why clouds are black is basically because there are many water droplets and the particles are too small. For example, the whole piece of silver is white, but the end of silver is black. When the sun shines on the surface of the silver block, because the surface is smooth and the incident white light is basically reflected, the silver block is white. Silver powder, its surface is composed of infinite small particles, so white light shines on it and rotates with each other, most of which is absorbed by it, and too little can be sent back to the air. Because we can't see the white light from its surface, it turns black. In a word, the cloud is black, which means that the cloud drops are tiny and numerous. Because it is too small, it falls slowly, and it takes 25 minutes to land from the bottom of the cloud. Under this cloud, the updraft is very strong and the advection wind is also very strong. This kind of water drop is often blown up by this updraft or advection wind before landing. So Aconitum appeared, just a gust of wind. On the contrary, the cloud is white, which is a phenomenon that the cloud drops are thick. When the cloud drops are big, it will easily fall to the ground and turn into rain. The size of raindrops is 10 times larger than that of cloud drops. "White-headed rain" is the truth.

* It's sunny on rainy days, but the roof is not sunny. (Sichuan)

On rainy days, the horizon is particularly bright, indicating that it will continue to rain; On the contrary, if the horizon is dark and the zenith is bright, it is a sign of sunny weather.

Of course, all rainy days are cloudy, and at the same time, because of air disturbance, the water vapor and dust on the ground are blown into the sky and distributed vertically, so the head-up visibility is particularly good, but the vertical visibility is worse. This is the reason why the sky is bright and the zenith is gloomy, and it is a harbinger of rainy days. When the atmosphere is stable, water vapor and dust are all concentrated in the low altitude on the ground, and the visibility at the head-up level is poor, while the visibility at the vertical level is excellent, so the zenith is bright and the ground level is gray. As the atmosphere became stable, it stopped raining.

* The fog can last for three days; The fog won't open, it's freezing. (Sichuan)

When the sun comes out, the fog disappears, so it can be seen that this fog is a low-radiation fog produced on a sunny day. The fog cleared the sunrise and the weather was fine. Because the radiation fog occurs in an anticyclone, it is unlikely that the weather will get worse in three days. If the sun comes out, the fog won't go away, the sun won't shine, and the weather is wet, people will feel particularly cold.

* I'm afraid that Nanyun will get up in the morning and Beiyun will pile up at night. (Chongming, Shanghai)

Chongming Island is located at the mouth of the Yangtze River, surrounded by water. Because of the different physical properties of water surface and land surface, the temperature of land surface is higher than that of water surface during the day and colder than that of water surface at night. In Chongming, if the south wind blows in the morning, the water is warm and the temperature is cold, so the atmosphere is cold up and warm down, so convection prevails, and there may be showers and thunderstorms. If the north wind blows at this time, the result will be the same. But if the south wind occurs at dusk, because the water surface is cold, it can only form fog on the water surface and must not condense into clouds; At dusk or at night, if the north wind blows, because the water surface is warmer than the north wind and the atmosphere is warm and cold, there will be severe convection, which will cause showers, so "I am afraid of north clouds at night." Generally speaking, in the morning, regardless of the south wind or the north wind, clouds can form on the water surface to cause rain; But at dusk, only when the north wind comes can it cause rain, and when the south wind comes, it can only become fog.

* The sky is cloudy with rain and snow. (Xiao Yaxin Nanshan in The Book of Songs)

The same cloud is a cloud with the same color all day, which is the shape of nimbostratus in the cyclone area. Rain clouds, there is "rain and snow" in parliament.

* The north and south are adjacent to each other, and the stream is flooded. (Fujian Fuqing Pingtan "Peasant Fisherman Congyan")

Seeing the clouds in the sky, the north and south are crowded, indicating that there is a conflict between the north and south airflow in the sky. This is either due to the vortex or the front, which can promote the airflow to rise and condense the water vapor into clouds and rain.

* White clouds and grass are exposed in Ying Ying. (The Book of Songs, Bai Hua)

"Ying Ying" is an adjective of Baiyun. There is no dew without clouds, and there is dew without clouds.

It's cloudy in the sky, and it's cloudy below, and it's going to rain soon. (Hubei)

* Clouds are like sports cars, no rain is the wind. (Wuxi, Jiangsu)

"The clouds in the sky are very tight" means that the light is covered by cumulus clouds, and "dark clouds are running below" is a phenomenon that broken rain clouds are flying. This is a typical typhoon or some kind of cyclone storm weather, so it will rain.

* Get up early, there will be no clouds in the east, and the sunrise will gradually dawn; It will be sunny in the west at dusk and sunny tomorrow. (Wuxi, Jiangsu)

* It's dark in the east and dark in the west, so don't wait for the bowl. (Wuxi, Jiangsu)
