What does summer mean?

Summer is a solar term reflecting the temperature change. "Chu" means to hide and die, and "early summer" means that the hot summer has passed. "Twenty-four solar terms" said: "Go, go, the heat is over." "Chu" means termination, which means that the heat is about to pass and the heat will end on this day. Summer represents a solar term in which the temperature changes from hot to cold.

Although it is a transitional solar term, it will not cool down immediately after summer. As the saying goes, "Summer is not summer, it is hot at noon". Look at the weather in the next few days. 20 degrees in the morning and evening is really cool, and it will rise to more than 30 degrees at noon. The good news is that this year's provincial capital is accompanied by thunderstorms, and it may not be hot at noon on the 24th. Specifically, from 2 1 night to today, it turns sunny and cloudy, with southerly winds of Grade 3, with the lowest temperature of 2 1 ~ 23℃ and the highest temperature of 32℃. It turned cloudy and cloudy on the 23rd, with thunderstorms or showers from afternoon to night. The lowest temperature is about 23℃ and the highest temperature is 365,438 0℃. On the 24th, it was cloudy with thunderstorms or showers, and the temperature dropped. Cloudy and sunny on the 25th-26th.

It is not enough to know the meaning of the solar term "summer". The second question is: how to pronounce the word "summer heat"?

Yesterday, the reporter also discussed with colleagues around him. As a result, some people read it three times and some people read it four times. Yesterday, the reporter inquired about the Modern Chinese Dictionary and found that the pronunciation of "Chu Shu" is three tones, but why it is three tones? There is no explanation in the dictionary. Generally speaking, as a place or unit, "Chu" is pronounced four times, and the rest are generally pronounced three times, such as "Fangzi". In the dictionary, "early summer" is a proper noun of one of the 24 solar terms.

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.

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. If you are not careful, it is easy to cause diseases such as respiratory tract, gastroenteritis and cold.
