Will it get cold during the day after the heat?

After the summer solar term, the dog days will end, the weather will gradually turn cold, and the temperature will gradually drop.

Summer solar terms mean that we are about to enter the autumn with meteorological significance. After the summer, the temperature in the area north of the Yellow River in China gradually drops.

It is not enough to describe the solar terms in summer simply by the beginning of temperature drop. Temperature drop is just one of the phenomena. The reasons behind this phenomenon are as follows: first, the direct point of the sun continues to move southward, and the solar radiation weakens; Second, the subtropical high moved southward by leaps and bounds, and the Mongolian cold high began to itch to try, punching and kicking, showing its edge.

Autumn tiger is the dominant subtropical high in summer. Although striding south, it will never give up its hegemony easily and retreat to the sea of the western Pacific easily. In the southern region under its control, people who just feel a little bit cool in autumn often feel hot weather at the end of summer, which is a veritable "autumn tiger".

For areas that have just stepped out of the dog days and suffered from severe summer drought, if they continue to be controlled by subtropical high, it is often easy to form drought in summer and autumn, which greatly advances the fire prevention period in autumn and needs vigilance. In the middle and lower reaches of the Yangtze River, it is often after the autumn tiger weather ends that the spring of clear autumn will come, but after 10, the general trend of heavy rain in all parts of the country will weaken during this period.
