Warning: It thunders in winter in many places now. Why is it bad to thunder in winter? Is it cold this winter?

Starting today, China will have a wide range of low-temperature weather, with heavy snow, heavy rain, strong winds and dust, which many people can't adapt to. After all, the temperature has been very high these days, and it can't stand the cold overnight.

As the poem says, "Like the strong wind in spring, it blows at night and blows open the petals of ten thousand pear trees." With the snowfall in some areas, the pace of winter has accelerated.

However, some people are curious, why does it thunder when the temperature drops? A netizen in Hunan said that it will be 65438+ February soon, but it will still thunder that day and wake up his dream.

Indeed, in recent days, there has been a phenomenon of "thundering for the winter" in many parts of the country, such as Hangzhou and Changsha.

As the saying goes, "It thunders and snows in winter", so how about it thunders in winter?

0 1, how about thunder in winter? It stands to reason that spring and summer are the high season for thunderstorms. At this time, the warm and humid airflow is active and the air is relatively humid. Coupled with solar radiation, the air near the ground is heated and constantly vacated, thus forming convective weather. With the appearance of strong convection, lightning will naturally occur.

However, since autumn and winter, because the air is relatively cold, the solar radiation ability is weak, the temperature near the ground is relatively low, it is difficult to form strong convective weather conditions in the air, and it is even more difficult to have thunderstorm weather, so it is difficult for everyone to see the phenomenon of "thunder and winter" in autumn and winter.

However, although "thunder can't move winter" is rare, it is by no means impossible. There are many places in Hubei, Hunan, Jiangxi, Zhejiang, Fujian and so on this year.

As for why, because the temperature in the south was generally warmer some time ago, the heating airflow was relatively strong. However, recently, the cold wave struck, strong cold air struck, and the warm and humid airflow was forced to rise, forming a strong convection, which led to the lightning phenomenon in winter and moon.

"Thunder and winter" is a normal weather phenomenon today, but people have long associated it with bad luck and misfortune, and formed many proverbs. For example, when it thunders in autumn, there are "thieves" everywhere, and "when it thunders in autumn, the grain is false."

There are also many proverbs about thunder in winter. These agricultural proverbs were summed up by our ancestors in the long-term experience. Although most of them are ominous, they still have certain reference significance today.

1, "Thunderstorm and rain in winter" Literally, if it thunders in winter, there will be more rain and snow, and the phenomenon of "thunderstorm and rain" will appear, that is, lightning weather will appear during the process of rainfall and snowfall.

As for why, it is mainly because the cold air in the south is very active and meets the warm and humid airflow on the ground, resulting in a fierce collision. The warm and humid airflow is transported to the cold air and forced to rise to form a vertical airflow, which leads to the phenomenon of "thunder, rain and snow".

This weather phenomenon shows that rain and snow will be very frequent in the next period of time, with obvious cooling and very cold in winter. Everyone should do a good job of keeping warm.

2. "It thunders in winter, and it keeps raining and snowing." The winter month is also November of the lunar calendar. Today is the sixth day of November, which naturally conforms to the scene of this agricultural proverb.

If there is a phenomenon of "thunder and winter" in winter, it means that strong convective weather is obvious, cold air prevails and warm air flow gradually fades.

In this context, rainfall and snowfall will continue for some time. After all, there is a lot of cold air and obvious precipitation in winter. As the temperature drops, this winter will be very cold.

3. The agricultural proverb "Thunder hits winter, ten cowpeas and nine empty pens" is somewhat exaggerated, but its original intention is to explain the cold weather in winter and remind everyone to do a good job in agricultural prevention.

The arrival of the weather phenomenon of "thunder and winter" is often accompanied by rainfall and snowfall. Especially with the blessing of the north wind, the cold air is powerful and prone to freezing rain, heavy snow and freezing.

In the cold background, besides people, cattle, sheep and other livestock have also been frozen. At this time, it is necessary to do a good job of preventing cold and keeping warm, otherwise there will be a phenomenon of "ten cowsheds and nine empty rooms".

Therefore, for aquaculture farmers, we must do a good job of keeping warm in the livestock shed to avoid air leakage in the shed, otherwise cows, sheep, pigs and chickens will easily freeze to death.

02, the strongest cold wave hit? Judging from the weather warning, since the 28th, the strongest cold wave has hit this year, bringing severe cooling, strong winds, rain and snow to the central and eastern regions, and most areas in the northeast will usher in small to medium snow, heavy rains in Jianghuai and Jiangnan.

It is predicted that the temperature will drop by 10- 14℃ from the night of 28th to the night of 30th, and it will drop by 16- 18℃ and 0℃ in the two lakes, central and southern Zhejiang, central and northern Guangxi, eastern Guangxi and southern Anhui.

With the arrival of the strongest cold wave, someone asked whether it was warm or cold this winter. In fact, agricultural proverbs have given the answer:

Literally, it means "rain and snow at the beginning of winter, and cotton in December". If 1 1 the temperature drops suddenly in the first half of the month, and it will rain and snow for a while, and it will become extremely cold in the twelfth month. Compared with previous years, it is necessary to add an extra layer of cotton to survive the winter safely.

Judging from the above statement, this year is likely to be a cold winter. Everyone should do a good job in keeping out the cold, and farmers should also do a good job in keeping crops warm.
