What does thunder mean in the first month?
And thunder when it snows is "thunder and snow". Experts believe that from a scientific point of view, thunder in the first month is a normal natural phenomenon, which has nothing to do with good luck. It is reported that in recent years, there has been thunder in winter in Nanjing, Suzhou, Shanghai, Wuhan and other places.
The ancients did not have a correct understanding of lightning. They think that thunder in the first month is not a good omen, and there is even a saying that "thunder in the first month, graves and valleys accumulate." However, from a scientific point of view, there is no problem with thunder in the first month, but it is a very normal natural phenomenon.
The formation of lightning:
As we all know, the lightning in thunderstorm season is the same as the ionization breakdown of insulating materials in high voltage electric field. In thunderstorm weather, the high-voltage electric field formed by charged clouds is very strong.
Usually, this is the case when charged clouds discharge to the earth. Clouds have a high potential in the positively charged region, while the earth has a low potential in the negatively charged region. Air is originally non-conductive, but under the action of strong electric field force, the outermost electrons of gas nucleus will be excited by electric field force to make a transition and form charged ions.
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.
