Spring thunder portends good omen

The agricultural proverb often says:

"Spring thunder strikes early, autumn harvest must be good."

"Spring thunder arrives early in good years."

@三月打雷麦谷堆"

March here refers to the third month of the lunar calendar, which is the time of early spring. In the people, it is often believed that spring thunder heralds a good year with good weather and rain.

Why does it thunder in spring?

The reason is: every spring, the obviously enhanced warm and humid air and the negative recalcitrant cold air fiercely confrontation, causing a strong air vertical convection movement, when the humid warm air rises to a certain height, a tall cumulonimbus cloud will be formed, and the strong electric field in the cloud makes the positive and negative charges collide and discharge, so that the thunder suddenly occurs.

So, where did thunder come from? - When it rains, some of the clouds in the sky are positive and some are negative. When the two clouds collide, they emit lightning bolts, and at the same time release a lot of heat, which heats and expands the surrounding air. The instantly heated and expanded air pushes the surrounding air, causing a strong explosive vibration. This is thunder.
