Why is it 8.23 in summer?

In summer, the direct point of the sun has moved from 23 26' north latitude to1128' north latitude. The sun reaches longitude 150, and the general time is August 23rd in Gregorian calendar.

It is not enough to describe the solar terms in summer simply by the beginning of temperature drop. Temperature drop is just one of the phenomena. The reasons behind 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, punching and kicking, showing its edge.

Although the subtropical high, which is dominant in summer, strides south, it will never give up its advantage easily and retreat to the sea of the western Pacific easily. In the southern region under its control, people who just feel a little cool in autumn often feel hot weather in late summer, which is a veritable "autumn tiger".
