Why is summer the hottest?

What is the high temperature in summer? Subtropical high control? As a result, since the high temperature in summer, the western Pacific subtropical high has been active in the middle and lower reaches of the Yangtze River. Once it is controlled, there will be high temperature, just like the high temperature some time ago. The so-called high-pressure control means that the hot air flow sinks under pressure, does not rise, and the heat keeps accumulating on the ground, absorbing more during the day and emitting less at night. When the heat reaches its peak, it is the hottest time in summer. This phenomenon continued until after beginning of autumn, when the subtropical high began to move southward and the heat dissipation increased at night? Leng Ye in hot weather? Phenomenon.

The relationship between summer heat and dog days

In the China lunar calendar, dog days are used to indicate the hottest time of the year. The calculation of dog days is more complicated. In some years, dog days are 30 days, and sometimes it is 40 days. There are 40 days in dog days this year, the first 10 day, the middle 20 days and the last 10 day. The first autumn of this year begins in July 14, and the 20-day mid-autumn begins tomorrow. One thing is certain, the summer heat is basically in dog days. The dog days are the hottest days of the year, with the highest temperature and the strongest yang.

The origin of summer heat and solar terms

Great summer heat is one of the 24 solar terms. Every year from July 22nd to 24th, the sun reaches120th. Summer solar terms also belong to the mid-festival stage, which is the hottest stage every year.

China ancient records? In mid-June, watching the heat? 、? The first15th day after the slight summer heat indicates that it is not the great summer heat, but the middle of June. Small and big are extremely hot, divided into sizes, small at the beginning and big at the back. ? Therefore, many ancient books in China have talked about the solar terms in summer. The ancient summer heat in China was divided into three periods: first, the rotten grass was firefly; Second, wait for the soil to moisten and cool off the heat; Just when it rains heavily. ? There are more than 2000 species of fireflies in the world, which are divided into aquatic and terrestrial species. Terrestrial fireflies lay eggs on hay, and when it is hot, fireflies ovulate, so the ancients thought fireflies were made of rotten grass. The second weather is that the weather becomes sultry and the land is wet. The third kind of weather is frequent thunderstorm, which weakens the heat and humidity, and the weather begins to transition to beginning of autumn.

I believe everyone knows, right? Trivolt fever? . Summer heat is generally in the middle of three volts. At this time, most parts of China are in the hottest stage of the year, and the temperature difference across the country is not large. Isn't there a proverb: March 9 is cold and mid-term is hot? .

The summer heat is also the season with the most thunderstorms. As the saying goes, the east flash doesn't bring a drop, and the west flash brings rain? It means that in summer, if lightning appears in the east, it will not rain, but if lightning appears in the west, it will rain soon.
