Extended data

The principle of thunder:

Lightning and thunder are common weather phenomena in summer, while it usually snows in winter. These are two completely different weather phenomena. However, as long as the weather in a certain place has the conditions of snow and thunder at the same time, these two completely different weather phenomena can appear at the same time.

In winter, the sky is overcast, the temperature of the upper clouds is below zero, and the water vapor in the clouds condenses into snow. When snowflakes fall from the clouds, they will melt into raindrops if the air temperature near the ground is high. On the contrary, if the temperature near the ground is low and the snow cannot melt, it will snow.

Thunderstorms are caused by strong convection of warm and humid air in some places. The sharp rise of warm air produces the violent vibration of cumulonimbus clouds, which will accumulate a lot of charges and produce lightning.
