What do you mean the sun turned into rain?

"The dog days passed and the sun turned into rain" means that just after the dog days, the hot weather turned into rainy weather.

The hot summer is a sign of cold climate, which indicates that "the hot summer is officially over", and the hot situation in most parts of China will turn to a turning point, and the weather will gradually turn cold.

It is not enough to describe the summer solar terms only by the beginning of the temperature drop, because the temperature drop is only one of the phenomena in this period. The reasons for this phenomenon are as follows: first, the direct point of the sun continues to move southward, and the solar radiation weakens; Secondly, the subtropical high has withdrawn southward by leaps and bounds, and the Mongolian cold high is eager to try, "punching out the feet" and showing its sharpness.

Under the control of the cold high pressure that began to affect our country, the sinking dry cold air formed, announcing the end of the rainy season in Northeast China, North China and Northwest China, and taking the lead in entering the beautiful time of crisp autumn.
