What is the reason for the sudden cooling? How to describe the sudden cooling

In winter, the temperature of the land is lower than that of the ocean, and a strong cold high pressure is formed in the interior of the continent, and the air flow diverges from the center of the high pressure to the surrounding areas, among which the air mass moving to the lower latitudes is a cold air mass in nature, and it meets the warm air mass to form a cold front. When the cold front transits, rainy (snowy) weather, wind, and cooling are formed, and after the transit, the temperature and humidity plummet, and the air pressure increases. In winter, the cold air mass moves rapidly southward (in the northern hemisphere, vice versa in the southern hemisphere), often forming disastrous winds to cool down the weather, or even form a cold wave.

A cold spell is coming. The cold wave is a large-scale weather process, that is, the cold air from the north invades our country on a large scale to the south, which will cause a wide range of sharp cooling, strong winds, rain and snow along the way, which generally occurs in late autumn, winter and early spring.

Because the climate is unstable in the season now, it is good to cool down frequently, pay attention to keeping warm, and wait for the temperature to stabilize. The whole country is cooling down, so if it gets cold, wear more clothes, and if it's so cold that it will be uncomfortable, the cold air will pass in a few days.

Late spring coldness refers to a weather phenomenon in which the temperature rises faster in early spring (generally refers to the end of February and early March), and the temperature is lower than that of normal years in the late spring (generally refers to April). Long-term rainy weather or frequent cold air invasion, or strong radiative cooling on clear nights under the control of continuous cold and high pressure can easily cause spring cold. The weather is changeable in early spring.

If the cold air is strong, the temperature can drop below 10, or even rain or snow. At this time, it is often sunny during the day, which makes people have a feeling of "warm wind smokes tourists drunk", but the cold air hits people in the morning and evening, making people feel that "the spring is cold". This kind of "fickle" weather that makes it difficult for people to adapt to is commonly referred to as the cold spring.

It is very easy to have an adverse impact on agricultural production and people's lives. ‍‍

As the climate warms, a large number of glaciers in the north and south are melting, note that there is a large amount, according to the number of 100 million tons of melting, you can go to Google Earth to see the appearance of glaciers and then find 40-50 years of ** comparison, and at the same time you can find some previous news to see, such as the melting of glaciers in Oteria, the disappearance of icebergs in Iceland and so on.

A strong cold air from Siberia affects most of our country from west to east, and it is also the strongest cold air process since November. Affected by the cold air, the cooling range in most parts of China is generally 6 12, and the cooling range in some parts of Xinjiang, most of North China, and some parts of the southern part of Northeast China can reach 14 16.

In the northern region of China, in this disastrous weather, mainly affected by the windy cooling weather, the cold air mass passed through the north to the south, did not form a front here, and there was no major snowfall weather, but the northern region was then included in the strong Asian high-pressure sphere of influence, and the degree of dry and cold weather is rare in recent years.

Areas of winter snowfall (the same is true for areas of summer rainfall) are located near fronts, i.e. at the junction of warm and cold air masses. This position is not fixed, it is determined by the strength of the forces of the two natures. The cold air mass is weak, and the front and precipitation area are higher latitudes, and the cold air mass is stronger, and the front and precipitation areas are lower latitudes.

Summer is over. The temperature will gradually drop, but there will be recurrences, especially in the autumn tigers, which will suddenly appear and raise the temperature. It's not like in the summer, it's still hot in the morning and evening, it's already cool in the morning and evening.

It's the same as a cold and fever in the human body, one hot and one cold, and it's dragging on...

There is a hot spot in the Pacific Ocean that has suddenly heated up.

The sudden cooling can be described in words and sentences.

1.Words: Plummeting temperatures, stormy weather, pouring rain, dripping into ice, storms, icy and snowy, wind and rain.

2.Sentence: (1) Li Bai's Chang'an is a month, and thousands of households pound clothes. The autumn wind blows endlessly, and it is always a jade relationship.

(2) Wang Wei's laurel was born in the autumn dew, and Qingluo was thin and did not change his clothes.

3) Du Mu's silver candle autumn light cold painting screen, light Luo small fan fluttering fireflies. The night is as cool as water, and you can sit and watch the morning glory Vega.

4) Du Fu's boundless falling trees are falling, and the Yangtze River is rolling. He is often a guest in the sad autumn, and he has been on stage alone for more than a hundred years.

5) Bai Juyi's pitiful third night of the first month of September, the dew is like a pearl and the moon is like a bow.

These words and sentences vividly convey the sudden drop in temperature.

What to pay attention to when the sudden drop drops I think you need to be careful to wear more clothes and never patronize beauty because beauty is to move You have to wear more thick clothes.

Pay attention to keeping warm, wear a mask when you go out, wear a hat to prevent the invasion of cold wind, pay attention to anti-freezing of the water meter in the corridor, pay attention to keep warm in the farmer's greenhouse, etc.

Pay attention to the cold and keep warm, add more clothes, and pay attention to the feet, because the cold starts from the feet.

Dress extra and keep warm.

The solar term has arrived.

When the solar term arrives, it is normal for the temperature to drop and the weather to become cooler. Under normal circumstances, the temperature of the natural world of Bailu is going to change, not to mention that the current solar term has reached the cold dew, with "the wild goose guests, the bird into the water for the clam, the chrysanthemum has Huanghua."

for phenology. The characteristic cold dew is a solar term that reflects the characteristics of the change of climate reputation, and the rapid drop of temperature is itself a major feature of the cold dew solar term. In the cold and dew season, after an autumn wind or an autumn rain, the temperature drops by 8-10 is relatively normal.

Precautions for temperature cooling.

As the saying goes, an autumn rain and a cold, if not, after entering the autumn, a few rains in recent days, do you feel very cool or even a little cool, especially the little friends who ride bicycles, it is simply going up to the wind, not only the road is more difficult, the most important thing is to be prepared to keep warm.

Although the weather in September is not very cold, but it can not resist the chill, it is recommended that you can bring a coat with you, the so-called preparedness, the important thing is not to let yourself freeze and catch a cold. A cold not only doesn't eat well or sleep well, but it also worries a lot of people who care about you, so you must take care of yourself.

When the weather changes, the temperature drops when cold air passes.

There is a strong cold air arriving causing a sudden cooling.

The cold air of Siberia is coming. Affected most of China.

The weather in winter is uncertain, and the wind has unpredictable clouds.

The solar term has arrived, and it is the time when the weather is cold and the snow is freezing.

It's the coldest season, it's very normal, and it's a cold wave again!

Because I'm going to freeze you, tell you that it's time to wear thick clothes!

An autumn rain and a cold.

When autumn comes, streams of cold air from Siberia move south into most of our country, and when it meets the warm and humid air in the south, which is gradually declining, rain is formed. The cold air moves southward again and again, often causing rainfall again and again, and lowering the temperature of the potato leakage field again and again. The number of rotten often forms a continuous autumn rain, and the next rain does not stop.

The weather is usually unpredictable, so be careful to add or remove clothes at the right time! Don't catch a cold!
