Who can explain why it thunders on snowy days?

The main reason is that the warm and humid airflow was strong before, and the cold air came down to produce strong convective weather, which triggered lightning activity. The simple point is that it was too hot a few days ago, and suddenly cold air came, forming a strong convection. Thundering on snowy days is extremely impossible in the history of meteorology.

There is a folk saying that "it thunders and snows in winter", and thunder in winter is a harbinger of snowstorms.

Pay attention to the snow:

1 first of all, in snowy days, we should pay attention to prevent falls, especially for the elderly. Due to the decrease of bone mineral density, it is easy to fracture after falling, and the healing after fracture is slow. On snowy days, because the outdoor roads are slippery, you should try to choose indoor sports and do less outdoor activities.

2. Keep warm in snowy days, because the temperature is low in snowy days, and people's resistance to diseases will decline. Especially young people who like fashion and beauty, they should not freeze people while being beautiful. In snowy days, try to wear thick clothes and eat more food produced by high calories to help resist the cold attack.
