What kind of climate change does it mean to be in summer today?

After the summer solar term, it means that the hot weather is coming to an end, but it does not mean that there will be no hot weather in the future. On the one hand, this year's "dog days" are not over yet. On the other hand, due to the influence of "autumn tiger", the high temperature will continue for a period of time after the summer, but the temperature will drop in the morning and evening, and there is still a high temperature of more than 30 degrees only at noon.

Climatic characteristics:

Temperature drop:

It is not enough to describe the summer solar terms from the end of August to the beginning of September 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 is crisp:

The cold high pressure that began to affect our country, under its control, formed sinking and dry cold air, which first announced the end of the rainy season in Northeast China, North China and Northwest China and took the lead in starting the best weather in a year-crisp autumn. In summer, only the northeast and northwest regions really enter autumn. But whenever cold air affects our country, if the air is dry, it will often bring windy weather, and if there is warm and humid airflow in the atmosphere, it will often form a decent autumn rain.

After every storm, especially after the rain, people will feel more obvious cooling. So there is a saying: "an autumn rain (wind) is a cold." There may be a large precipitation process in the north and south Jianghuai areas. The temperature dropped significantly, and the temperature difference between day and night increased. It is sunny after the rain, and people often don't adapt to the cold and hot changes at the turn of summer and autumn. Careless can easily lead to respiratory diseases, gastroenteritis, colds and other diseases, so it is called "eventful autumn".
