Proverbs of thick clouds in the morning

Clouds are mysterious, so what proverbs describe rain and fog? Please read the details of the proverb I brought.

Clouds begin at midnight and the rain stops at midnight. (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)

* Clouds, rain will pour. (Anhui)

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

The so-called "chaotic cloud crossing", "cloud crossing", "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".
