What did beginning of winter say about thunder?

There is a saying in beginning of winter that there are piles of graves when it thunders in winter.

This old proverb means that if it thunders in winter, especially during the solar term in beginning of winter, it is not a good sign. It often indicates that the late winter will not be peaceful, and many old people will die because of colds, illness and other reasons. In the past, there were many agricultural proverbs like this, such as "When it thunders in winter, all ten cowsheds are empty", which means that when it thunders on the day when the solar term starts in winter, nine of the ten cowsheds will be empty, because all the cows have died of illness.

This is also an exaggeration to describe that this kind of weather is abnormal, which leads to the particularly cold weather behind. In addition, there is a saying that "it thunders in winter and builds new graves everywhere", which also means this. In some places in the north, there is a saying that "it thunders and snows in winter", that is to say, if it thunders in winter, it is often prone to heavy snow and even snowstorms.

A detailed explanation of the weather

If it rains and thunders in beginning of winter, it means that the whole winter is cold, rainy and snowy, and it is prone to some extremely cold weather, which is not good. The old rural proverb "Ten cowsheds, nine empty sheds and thunder in winter" shows that if it starts to rain and thunder in winter, it means that the climate will change this winter, there will be more ice and snow, and extreme weather such as hail is very likely. Because when the hot and humid air in a certain area heats up, the cold air in the north will be stronger, so the cold and humid air will meet.

Lighter warm and humid air will rise rapidly due to the impact, while heavier cold air will fall rapidly, which will directly lead to the instability of the atmospheric structure and meet the conditions for the formation of thunderstorms, and then thunderstorms or thunderstorm weather will occur. If the hot and humid airflow in the air is particularly strong, the convective movement will be too strong, and even hail weather may occur (the above contents are for reference only).
