Which season is the hottest in summer?

Long summer is the 14th solar term among the 24 solar terms, and autumn is the second solar term. Speaking of summer, it has reached the "last summer" in the "three summers" of high temperature and hot weather, which means that the hot and difficult weather has come to an end and summer is gradually disappearing. Thunderstorm activity is not as active as summer, and the general trend of rainstorm in all parts of the country is weakened.

In summer, the bucket handle of the Big Dipper points southwest (E position). When the sun reaches longitude 150, the node time is around August 23rd in Gregorian calendar. In summer, the direct point of the sun has moved from 23 26' north latitude to1128' north latitude. At this time, if you watch the Big Dipper at night, you will find that the curved bucket handle still points southwest. The arrival of the hot summer also means entering the second half of the dry calendar.

The historical origin of the summer heat:

Entering summer is a solar term that reflects the change of temperature. The original meaning of "going out" means "stopping" and "staying". "Three summers" and "three days" both represent hot and humid weather, and the curves on the time axis and the temperature axis are basically the same: summer is coming, summer is coming; When the sky falls, summer is over.

There are "three summers" in the 24 solar terms, namely, little summer, big summer and long summer, followed by early summer, heatstroke and late summer. There is also a "beginning of autumn" solar term in the middle of the "Three Summers". After beginning of autumn, it is summer, and the heat lasts for a long time. Long-term intense heat is beneficial to the growth and yield of crops. The ancients called the period from beginning of autumn to the autumnal equinox "long summer".

The dog days include four solar terms: Slight Summer, Great Summer, beginning of autumn and Summer. By the time of the heat, the dog days have passed or ended. The summer heat subsides slowly, and it doesn't get cold as soon as it drops. Although the summer solar term is still hot, the temperature has generally begun to show a downward trend.
