Wrestling in summer

Among the 24 solar terms, the name of summer is different. Because of its name "summer heat", it is often considered as a summer solar term, but as everyone knows, the season has entered autumn; The "summer heat" here does not refer to the same temperature intensity as the solar terms such as Great Summer Heat and Minor Summer Heat, but refers to the end and a state of summer heat.

"Twenty-four solar terms" said: "Go, go, the heat is over." This explains the meaning of "summer heat": summer heat begins to decline. Its astronomical and meteorological significance is that the direct point of the sun continues to move southward, the radiation weakens, the subtropical high withdraws southward, the number of times the Mongolian cold high moves southward increases, and the temperature begins to drop obviously. As the saying goes, "it is not hot in summer, but hot at noon", that is, it is only hot for a while at noon in summer, and it is cool in the morning and evening. Therefore, summer heat is a solar term, which means from hot to cold.
