China Weather Official WeChat has launched a national anti-freeze map. Why do Nanjing people rank first in anti-freeze index?
In the China Weather Network’s official Weibo poll on who is more frost-resistant, 600 netizens voted for southerners, while 200 netizens voted for northerners. . Some netizens joked that you were eating popsicles in a northern city, while I was shivering on the streets in the south. The winter equipment of northerners has high armor, and the anti-freeze properties of southerners are also low.
According to relevant news from the China Weather Network, the first cold wave weather since the beginning of winter this year will sweep across our country from north to south on the 12th. The Central Meteorological Observatory also issued a four-day cold wave warning in most parts of northern my country on the 13th. We experienced the lowest temperature since the beginning of winter. At the same time, due to the cold wave, the south and north were severely cold. The lowest temperatures in 19 provincial capital cities across the country broke record lows.
From the perspective of meteorological conditions, the temperature in the north is indeed much lower than that in the south, but why do everyone think that southerners are more resistant to frost than northerners? According to the explanation of meteorological analysts, the Qinling Mountains and the Huaihe River are The boundary is the dividing line between the north and the south of my country, and it is also one of the dividing lines that divides central heating areas. There is central heating in northern China, but there is no central heating in scenic spots in the south. Although the outdoor temperature in the north is low, even the highest temperature in some areas is below zero. However, due to the function of indoor heating, the indoor temperature is generally more than 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 of southerners is higher than that of the north. Much lower. Therefore, people who have lived in the south for a long time will have stronger adaptability to cold environments.
According to meteorological analysts, although the overall temperature in the north is relatively low, the addition of heaters in the north is a physical anti-freeze, while in the south there are no better measures to keep warm, so it is not All areas are frost tolerant. Ranked according to the lowest average temperature, relative humidity and other factors, Nanjing has the highest anti-freeze index, so it deserves to be the most anti-freeze city.
