Why does it rain heavily in summer?

There are many opinions about why it rains heavily in summer, that is, when is summer and there is no river bank in summer; The sun doesn't shine in summer, and the stones are exposed in summer; There is thunder in summer, and Huangmei is half a month.

1, what time is it in summer? There is no river bank in summer.

It rains in many places in summer. The ancients found that if it rains in summer, it will rain heavily and rainstorm in summer. Therefore, flood control and waterlogging prevention are particularly important. In some places, there is a saying that "it's a big summer and a small summer, killing mice", and there is also an experience summary of "there is a south wind in a small summer and a drought in a big summer" and "there is thunder in a small summer and waterlogging in a big summer". But the weather is different every year. This statement has almost no scientific basis and can only be used as a reference.

2. The sun won't shine in summer, but stones will bloom in summer.

This proverb means that if the solar term in summer is rainy instead of sunny, then the weather in summer will be fine and the temperature will be high. The ancients used "drying stones" to describe the vicious sun that day. There are similar sayings in many areas, such as "it's too hot in summer, but it's chilly in summer" and "it's too hot in summer". So this is a folk proverb based on the local climate characteristics.

3, it's a little thunder in summer, and I'll be Huangmei for half a month.

Thunder is also closely related to the rainy season. In Shanghai, there is a saying that "it thunders in a small summer, and the yellow plum blossoms in a half moon", that is to say, if it thunders in a small summer, it indicates that the rain belt will stay in the middle and lower reaches of the Yangtze River for some time. For example: "Little summer thunder, Huangmei returns; It's eighteen days to pour Huangmei, and there is also "thunder on the head in summer, and Huangmei is against it in half a month." In Jiangsu, there is also a saying that "one summer and one thunder brew seventy-two wild Huangmei".

Summer is the eleventh of the twenty-four solar terms, at the end of the afternoon and the beginning of the month. The sun reaches longitude 105 degrees, and the festival is held on July 6-8 of the Gregorian calendar every year. Summer means hot, a little hot, not very hot. It's getting hotter, but it's not the hottest. Although light summer is not the hottest season in a year, it is followed by the hottest solar term in a year. There is a folk saying that "it is hot in summer and hot in summer, and it is steamed and cooked". Many places in China have entered the season with the most thunderstorms since summer.
