Why does it always rain in Tomb-Sweeping Day? Three reasons to solve your confusion

First of all, I want to talk about this season, which exists at the juncture of alternating cold and warm. Anyone familiar with geography will be familiar with this principle. As long as there are cold and warm air currents, there will be rainy days. After a cold winter and a warm spring, this solar term connecting the past and the future naturally becomes the middle dividing point, so this is the best condition for the formation of rainy days when cold and warm air collide with each other.

Secondly, because spring is a low-pressure season, this low-pressure weather will make the formation of clouds more obvious, and spring is also a windy season. This combination will naturally blow the clouds quickly, so it will be rainy and rainy every spring. As an important solar term in spring, Tomb-Sweeping Day naturally undertakes this important task, and people will think that Tomb-Sweeping Day often sees rainy weather.

The third reason is that there will be a lot of water vapor in the atmosphere during Tomb-Sweeping Day. Although spring has come at this time, the temperature difference between morning and evening is still very large. At night, it will become several degrees lower than during the day, further aggravating the speed of water vapor condensation in the atmosphere. At night, it will become Mao Mao rain and float to the earth with the breeze.
