Long summer is one of the twenty-four solar terms in China lunar calendar, which means the last solar term in summer. The summer heat means that the summer heat gradually fades, indicating the prelude to entering autumn.

Meteorological changes of high temperature in summer

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 southern areas under its control, it is often late summer, and 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.
