Why does it thunder and rain in winter?

It is normal to have heavy rain under thunder in winter, which is caused by the active warm and humid airflow and may cause crops to be affected.

The heavy rain in winter shows that the air humidity is high and it is easy to cause a series of rain and snow disasters, so there is a folk saying that it thunders and snows in winter.

If there is too much ice and snow and the temperature is too high, it will not only have a negative impact on crops, but also have a direct impact on people, poultry and livestock, inducing diseases, causing people or animals to suffer from freezing damage and even death.

Causes of thunder and heavy rain in winter

Although the phenomenon of rain and thunder in winter is rare, it is not unique, and it occurs in many parts of the country. When the weather is hot and cold, there will be more opportunities for "thunder in winter". Under the influence of strong warm and humid airflow and strong cold air, the warm and humid air in the lower layer was forced to rise, resulting in strong convection, which created conditions for the formation of lightning. After the "beginning of winter", it thundered in winter.

Winter is controlled by the continental cold air mass, the air is cold and dry, and the solar radiation is weak. In addition, the weather is warmer in winter and the warm and humid airflow is stronger. When the cold air in the north occasionally goes south, the warm and humid air is forced to rise, and the convection intensifies, which will form a thunderstorm and produce the so-called "thunder into winter" phenomenon.
