“ Why is the dog days the hottest day of the year? After entering the dog days, the surface humidity increases, more heat is absorbed every day, less heat is emitted, and the heat of the surface layer accumulates. Therefore, it is hotter every day. When entering the dog days, the accumulated heat of the ground area reaches the peak, and the weather is the hottest. In addition, there is more rain in summer, the air humidity is high, and the heat capacity of water is much larger than that of dry air It is also an important reason for the muggy weather. In July and August, the subtropical high was strengthened. Under the control of the subtropical high, the downdraft inside the high pressure made the weather clear and less cloudy, which is conducive to sunlight, and the ground radiation increased, making the weather hotter.
