Winter weather network

According to the related news of China Weather Network, on 12, the first cold wave weather will sweep across China from north to south this winter. The Central Meteorological Observatory also issued a four-day cold wave warning for most parts of northern China on 13. It has experienced the lowest temperature since winter, and at the same time, the south and the north are cold together because of the cold wave. The lowest temperature in national 19 provincial capital cities hit a record low.

In a poll released by China Weather Network official Weibo, 600 netizens voted for southerners and 200 netizens voted for northerners. Some netizens teased you for eating popsicles in the northern cities, and I shivered in the southern streets. Northerners have high armor in winter, while southerners have high frost resistance.

According to meteorologists, although the overall temperature in the north is low, not all areas are frost-resistant because of the heating in the north and the lack of better warm-keeping measures in the south. According to the lowest average temperature, relative humidity and other factors, Nanjing and Hefei have the highest frost resistance index, which is worthy of being the most frost-resistant cities.

In terms of meteorological conditions, the temperature in the north is indeed much lower than that in the south, but why do people think that southerners are more frost-resistant than northerners? According to the explanation of meteorologists, the Qinling Mountains and Huaihe River are the dividing lines between the north and the south of China, and they are also one of the dividing lines that divide the central heating areas. There is central heating in the north of China, but there is no central heating in the south scenic spot. Although the outdoor temperature in the north is low, even the highest temperature in some areas is below zero. But due to indoor heating, the indoor temperature is generally above 10℃. Although the temperature in the south is a little higher than that in the north, the temperature difference between indoor and outdoor is very small. Relatively speaking, the indoor temperature in the south is much lower than that in the north. Therefore, people who live in the south for a long time will be more adaptable to the cold environment.
