What is the sign of hail?

Question 1: What are the signs of hail? It is similar to the precursor of a thunderstorm, but the difference is that the cold current is stronger, and the water vapor condenses into ice cubes and falls to the ground.

Question 2: Signs before hail 5 points Since ancient times, the signs before hail such as frogs chirping and swallows flying low have been relatively well-known to people, and they are quite accurate. There are several other types:

Ants crossing the road - ants that dig holes in the ground and live in them. They feel that the holes will be flooded if it rains, and they will run away before it rains.

Earthworms coming out of their holes - The ground is moist and soft, and earthworms will crawl out of the ground, indicating that it will rain.

Other signs before rain include swarms of mosquitoes, swarms of rain ants, cats washing their faces, etc.

Swallows flying low in the snake aisle

Heavy rain is coming soon!

Dragonfly flying low

In summer, if you see a frog *** next to a pond, it means it is going to rain.

In the city, if you see the weather becoming cloudy and swallows flying low, it means it is going to rain. .

But if you just look at the swallows flying low, I often see swallows flying low! ! It didn’t rain either! ~

Dragonflies also fly low, fish jump out of the water, earthworms and snakes crawl out of their holes, the tide returns on the ground, there are water droplets on the stones, frogs make hoarse calls, and people with tinea manuum and athlete's foot feel itchy. Small blisters,

Dogs will eat grass!

For thousands of years, the working people of our country have summarized rich experience of "looking at clouds to understand the weather" based on changes in cloud shape, direction, speed, thickness, color, etc. in production practice. And weave these experiences into proverbs. We have gathered together these proverbs about "looking at the clouds to know the weather". Friends who are interested may wish to pay attention and make some observations and comparisons.

"There are clouds in the sky and rain on the ground": Meteorologically, cirrus clouds are called cirrus clouds. They generally appear in front of warm fronts and low pressures. The appearance of cirrus clouds indicates that fronts or low pressure are coming. , is the harbinger of rain. However, when clouds appear after rain or in winter, there will be continuous sunny days or frosts. Therefore, there are also proverbs like "clouds dissipate and sunny days lead to drought" and "clouds in winter cause dust in the sun".

"Fort clouds, drenched with rain": Fort clouds refer to fort-shaped altocumulus clouds or fort-shaped stratocumulus clouds. They often appear in front of low-pressure troughs, indicating that the air is unstable. Thunderstorms usually occur every 8 to 10 hours. .

"Clouds cross clouds, rain falls": Clouds cross clouds means that the upper and lower clouds move in different directions, which means that the wind direction at the height of the clouds is inconsistent. It often occurs near fronts or low pressure, so it indicates rain. Sometimes the direction of the clouds is opposite to that of the wind on the ground, and there is a saying that "when clouds move against the wind, the sky will change."

"*** Crossing the river, heavy rain is pouring": *** refers to the broken rain clouds under the nimbus clouds. The appearance of such clouds indicates that there is sufficient water vapor in the nimbostratus clouds and heavy rain is coming. Sometimes broken rain clouds are blown by strong winds to cloudless places, and at night you can see clouds like *** floating across the "Milky Way", which is also a precursor to rain.

"Cotton cloud, rain is coming soon": Cotton cloud refers to fluffy altocumulus clouds. The appearance of this kind of cloud indicates that the middle atmosphere is very unstable. If there is sufficient water vapor in the air and there is upward movement, cumulonimbus clouds will form. , there will be a thunderstorm coming.

"The sky is covered with gray cloth, and the rain is continuous.": Gray cloth clouds refer to nimbostratus clouds, which are mostly formed by the lowering and thickening of altostratus clouds. They are very large and thick, and there is sufficient water vapor in the clouds. They are often Produces continuous rainfall.

"When clouds go to the east, cars and horses can pass; when clouds go to the south, the water swells; when clouds go to the west, it is covered with raincoats; when clouds go to the north, it is good for wheat to dry": predicting cloudiness and sunshine based on the direction of cloud movement, Clouds moving east and north indicate fine weather; clouds moving west and south indicate rain is coming. The direction of cloud movement generally indicates the wind direction at its height. This proverb describes the distribution of clouds in different parts of the low pressure. It is suitable for low and fast-moving clouds that are dense throughout the sky.

"Dark clouds catch the setting sun, and if it does not set today, it will set tomorrow": refers to when the sun sets, a dark cloud like a city wall rises under the western horizon to catch the sun, indicating that the dark clouds are moving eastward and the rainy weather is moving to the west. , it's going to rain. Generally speaking, if there are medium clouds, it will rain that night; if there are high clouds, it will rain the next day. However, if the dark clouds in the west appear in strips or disconnected, or the local area is originally cloudy, it is not a sign of rain in the future.

"The sky in the northwest is unlocked, and the sun is shining brightly in the Ming Dynasty": refers to the clouds in the northwest that split open on rainy days, revealing a piece of blue sky, which is called "the sky is unlocked". This shows that the local area is already at the rear of the rainy weather system. As the rainy system moves eastward, the local rain will stop and the weather will improve.

"The sun appears once and does not see you for three days": refers to spring and summer, at noon on a rainy day, the clouds break up and the sun shows its face, but the clouds quickly gather and thicken, which indicates that the local Under the influence of the quasi-stationary front, the airflow near the quasi-stationary front rises and falls strongly and changeably.

When the updraft strengthens, the clouds thicken and the rainfall increases; when the updraft weakens, the clouds thin and the rainfall decreases or stops; around noon, the sun shines strongly and the upper part of the clouds is heated... >>

Question 3: What does the orange hail warning mean? The orange hail warning refers to the possibility of hail accompanied by thunder and lightning within 6 hours, and may cause hail damage.

Preventive measures

⒈ Pay attention to weather changes and be prepared for hail and lightning protection;

⒉ Properly place outdoor items and small items that are susceptible to hail Cars, etc.;

⒊The elderly and children should not go out and stay at home;

⒋Drive poultry and livestock to a safe place with a roof;

⒌Do not enter isolated shacks, sentry boxes and other buildings or under large trees. When thunder and lightning occur, you should turn off your mobile phone;

Dream Example

A man dreamed of hailstones as big as watermelons falling, getting bigger and bigger, and finally fell like a mountain. But when the hailstones were a few centimeters away from him, Suddenly it melted, and the water it turned into washed him away.

Analysis

Hail is water droplets from the sky that condense into ice cubes and fall to the ground. Ice is something that should only be produced in winter, but hail mostly falls from the sky in summer. Therefore, hail symbolizes blows and generally represents hidden emotions. The hail melts, which represents the release of certain emotions, and the dreamer's heart will become warmer and warmer. The melted hail turned into water and washed away the dreamer, which means that the dreamer is still overwhelmed by a bunch of emotions or things and must slowly adjust.

Question 8: What is the meaning of hail in the Beginning of Summer? This kind of strong convective weather usually occurs in summer. In the thick and strong cumulonimbus clouds in summer, this meteorological condition may produce hail or thunderstorms. However, in most cases, only thunderstorms and rain are produced. This is because the requirements for producing hail are more stringent. Meteorologists tell us whether hail is produced depends on the thickness of the cumulonimbus cloud and the location of the top of the cloud. It is related to the height and temperature of the atmosphere, the speed of updrafts, etc.

False

If cumulonimbus clouds are particularly thick and the upper part of the cloud layer is in a very high atmospheric space, the temperature there will be will be very low, and the small water droplets will be sent to the low-temperature area in the upper part of the clouds by the updraft, and will be frozen into tiny ice particles. Even during the descent

they will be affected by the low-altitude summer high temperature, and some It melts, but refreezes when it is sent to high altitude again by the airflow. In this way, it goes up and down repeatedly with the airflow. As long as the high-altitude low-temperature clouds below 0℃ have enough thickness, the ice particles are slightly melted and then frozen again. Because it melts slowly and freezes quickly, the ice particles continue to absorb moisture from the clouds as they rise and fall repeatedly. As a result, the ice particles become larger and larger as they freeze. When the updraft can no longer support them, they fall to the ground and form hailstones.

Press

According to calculations by meteorologists, thunderstorms can be produced when the speed of updraft is around 10 meters/second; but only when the speed of updraft reaches more than 20 meters/second, Hail will be produced. Moreover, the high-altitude part of the cumulonimbus cloud layer below

0℃ must have a large thickness to ensure that small water droplets or small ice particles rise with the airflow and stay in the low-temperature area. The time is enough to be frozen into ice, and ensure that the melting speed during repeated lifting and lowering is slower than the freezing speed. Only in this way can the small ice particles become more frozen as they move up and down with the airflow. The bigger it becomes, the larger it becomes, and eventually it becomes so big that the airflow cannot support it and it falls to the ground and turns into hail.

This kind of special meteorological condition is quite rare. Even in the summer, there are not many opportunities to occur, and it is even less likely to occur in other seasons, so The chance of hail falling is very small, and it mainly occurs in summer.

Our country

Most of the hail disasters in China occur from April to July, usually from the afternoon to the evening. Because this Cold and warm air activities are frequent within a period of time, making it relatively easy to form special meteorological conditions for hail to fall. Judging from the regions where hail falls in my country

, there are more mountainous areas and plateaus than plains and basins; more inland and less along the coast. ; There are fewer in Northeast China, Xinjiang, *** and areas south of the middle and lower reaches of the Yangtze River, while there are more in mid-latitude Yunnan, Guizhou, Inner Mongolia, Gansu, Shaanxi, Shanxi, Ningxia,

Henan and northern Jiangsu. .

Since the meteorological conditions for the formation of hail are severe and generally difficult to maintain continuously, the time for hail to fall is usually short. Common hail only falls for a few minutes to half an hour. In addition, hail falls The area is not too large, generally distributed in a strip with a width of 1000-2000 meters.
