2, "Twenty-four solar terms": "Summer heat, summer heat is also divided into sizes, small at the beginning of the month, large in the month, and still small today." Summer heat, which means hot, is a little hot, not very hot. It means that the weather is getting hotter, but it is not the hottest, and most parts of the country are basically in line with it. At this time, the Meiyu in the Jianghuai Basin is coming to an end, and the temperature in long summer has risen and entered the summer drought period; However, when North China and Northeast China entered the rainy season, tropical cyclones were active frequently, and the number of tropical cyclones landing in China began to increase.
