The second solar term in autumn

As the second solar term after autumn, the arrival of the hot summer means that the dog days of the hot summer are completely over. Every year from August 22nd to 24th in the solar calendar, the summer weather gradually cools down, so it also means "out of summer".

The intense heat means that the hot summer is coming to an end, and at this time, the hot and difficult weather has come to an end and the summer heat has gradually subsided. Although the weather is still sultry, it has shown a downward trend. The summer heat is the 14 solar term among the 24 solar terms, and it is the summer heat when the longitude of the sun is 150, and the time is from August 22 to August 24 of the Gregorian calendar every year.

Introduction.

In summer, the average temperature in South China is 65438 0.5℃ lower than that in early autumn. In some years, in late August, there will be a low temperature below 23℃ in western South China for three consecutive days, which is likely to affect the flowering of hybrid rice.

However, because South China is basically controlled by the summer monsoon at this time, the average temperature in some areas will be above 30℃, and even the high temperature of 35℃ will appear in some parts of eastern South China. Now, the northwest plateau, especially the plateau above 3500 meters above sea level, has shown the scene of early winter, with grass withering and frost and snow increasing.
