In which season is the summer term?

In summer, that is, "out of summer", the high temperature will gradually withdraw. Summer is the fourteenth of the twenty-four solar terms, and autumn is the second. Dou Zhiwu (Southwest); The solar meridian reaches150; Celebrated every year from August 22nd to 24th in the Gregorian calendar. Summer has arrived, which is the "last summer" in the "three summers" of hot and hot weather, which means that the hot and difficult weather is coming to an end.

After the summer, the direct point of the sun continued to move southward, the solar radiation weakened, and the subtropical high retreated southward. As the height of the sun decreases, the heat it brings also decreases. The arrival of summer means that the hot and difficult weather is over. During this period, the weather is still hot, but it has shown a downward trend. There are many folk activities in summer, such as eating ducks, setting off river lanterns, opening fishing festivals, decocting medicinal tea and offering sacrifices to the land.

Introduction of meteorological changes in summer;

The disappearance of summer heat is a slow process. It doesn't mean that it gets cold immediately after the heat drops in summer. Generally, coolness will begin after the Millennium. After summer, the temperature gradually decreases and the temperature difference between day and night gradually increases, but the temperature is still high during the day. The reasons for this phenomenon are as follows: first, the direct point of the sun continues to move southward, and the solar radiation weakens; Second, the subtropical high moved southward by leaps and bounds, and the Mongolian cold high began to itch to try.

After the summer solstice solar terms, although the subtropical high strode south, it would never give up its dominant position easily and easily retreat into the sea of the western Pacific. In the controlled southern areas, often in late summer, hot weather is felt again. This is the short-term regenerative weather "autumn tiger". The duration of autumn tigers varies from year to year, usually lasting from half a month to two months.
