What is the first frost temperature? What does ChuShuang wear? Temperature characteristics of the first frost.
What is the first frost temperature? In the first frost, the temperature dropped in most parts of the country, but it will return to normal in some places, but the overall temperature is still very cold. The first frost is one of the twenty-four solar terms and the last solar term in autumn. So what is the temperature of the first frost? Let's take a look!
First frost temperature:
The solar term of the first frost means that the weather is getting colder and first frost begins. To the south of latitude, the average temperature is around 16℃, and there are three solar terms before the first frost day. In the southern valley of South China, frost can only be seen in the dead of winter. Of course, even at the same latitude, the temperature and humidity of the air close to the stratum are different due to the difference of altitude and topography, and the first frost period and frost day are also different. In the first frost season, the cool autumn wind blew to Guangzhou, the flower city. The average temperature in northeast China, eastern Inner Mongolia and most parts of northwest China has been below 0℃.
"The first frost in the first frost" reflects the climate characteristics of the Yellow River Basin. As far as the annual frost days are concerned, there are frost and snow in some parts of the Qinghai-Tibet Plateau even in summer, and the annual frost days are over 200, which is the place with the largest number of frost days in China. The annual frost days in eastern Tibet, southern Qinghai, Qilian Mountains, western Sichuan Plateau, northwestern Yunnan, Tianshan Mountains, Altai Mountains, western mountainous areas of northern Xinjiang, northeast China and eastern Inner Mongolia all exceed 100 days, and the vast areas south of Huaihe River, Hanshui River and east of Dongpo of Qinghai-Tibet Plateau are all below 50 days, with only the annual frost days in the south of 25 north latitude, Sichuan Basin, south of Fuzhou and coastal areas of Guangdong and Guangxi being/kl.
The first frost in autumn is called the first frost. The earlier the first frost, the greater the harm to crops. The first frost in all parts of China is gradually delayed from north to south and from mountainous areas to plains. Except for areas with frost all the year round, frost first appeared in the north of Daxing 'anling, usually at the end of August. The first frost in most parts of Northeast China, Inner Mongolia and Northern Xinjiang is mostly in September. 10 Frost has appeared in Shenyang, Chengde, Yulin, Qamdo and Lhasa. 165438+1Frost has been seen in Shandong Peninsula, Zhengzhou, Xi 'an and northwest Yunnan in early October; Frost did not appear in eastern China, Hanshui and Yunnan provinces until the beginning of 65438+February. When first frost went from Xiamen and Guangzhou to Baise and Simao, it was the beginning of October after 65438+ years.
What does ChuShuang wear? The average daytime temperature during the first frost is 20℃. It is recommended to wear comfortable clothes, such as short suits, T-shirts, thin jeans, casual clothes and professional suits made of single cotton and linen fabrics.
The average night of the first frost is 10℃. It is recommended to wear warm clothes such as suits, jackets, coats, suits and thin sweaters.
Please refer to the local weather conditions for actual dressing.
That's enough about the temperature of the first frost and what kind of clothes to wear. If you really arrive at the first frost, you must keep warm.
Is the first frost still hot? Although it means that there will be frost in the first frost, the weather situation is more complicated because of the wide latitude distribution in China.
If the human body feels 25℃ as the standard, the national average temperature before and after the first frost is 10℃ ~ 20℃, the highest temperature cities are Sanya, Beihai and Fuzhou, and the average temperature is around 25℃. The cities with the lowest temperature are Harbin, Changchun, Yinchuan and Hohhot, and the average temperature is around 1℃.
Therefore, it can be judged that even the city with the hottest first frost will not make people feel hot, but generally feel comfortable, while parts of the north have entered cold weather.
