How about thunder in winter? ?

The ancients thought that thunder in winter was a very rare image. If it happens, it indicates that something bad is going to happen. This is because in the eyes of the ancients, the attribute of lightning is positive, and it only appears in the summer when the sun is strong.

Winter is the season when everything returns to Tibet. Because the temperature drops, everything is hidden and the sun is not exposed, so lightning is hard to appear. If it thunders in winter, it means that the world can't hide the spirit of the sun, which is called "disturbing the sun" and even animals will suffer. Therefore, there is a saying that "more thunder and less rain, ten cowsheds and nine empty".

Formation of thunder

The scientific explanation is that two charged clouds in the sky, a positive electrode and a negative electrode, collide with each other to produce a discharge phenomenon. Moreover, this discharge phenomenon will release a lot of heat, and the release of heat will heat and expand the surrounding air.

Instantly heated and expanded air will push the surrounding air and produce strong explosion vibration, which is thunder. The scientific statement is that "air produces violent up-and-down convection."
