What are the phenological characteristics of intense heat?

1. Slight summer heat is the fifth solar term in summer, and the time is between July 6 and 8 of the Gregorian calendar every year, when the sun reaches 105 degrees.

2. There are three periods of summer heat: "When the wind is warm; Second, wait for crickets to live in space; The third waiting eagle began to crow. " Warm wind means that after a slight summer, there is no cool wind on the earth, and all winds have heat waves. Crickets living indoors means that after five days of light summer, due to the heat, crickets leave the field and go to the corner of the yard for the summer. The beginning of the Eagle Cup means that the eagle is in the cool high air movement, because the ground temperature is too high. In summer, the weather is hot, thunderstorms are frequent and rainfall is abundant, and crops have entered a vigorous growth stage. Most areas in southern China enter the season with the most thunderstorms, which are often accompanied by strong winds and heavy rains, and sometimes hail occurs, which is easy to cause disasters, so we should pay attention to prevention.
