Meteorological changes 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.

After the solar terms in summer, the thunderstorm activity is not as active as that in hot summer, and the general trend of rainstorm in all parts of the country is weakened. During the summer solar term, the rainfall distribution in South China changed from more in the west to less in the east. In the southwest and west, there are more thunderstorm activities due to the subtropical high edge and mountains.

In September, most parts of China began to enter a period of less rain, while there were more autumn rains in West China, which is a unique weather phenomenon in autumn in West China. Under the control of cold high pressure, sinking dry cold air is formed, and the rainy season ("seven rains and eight highs") in Northeast China, North China and Northwest China is over.
