What is the coldest place in China?
The coldest place in China is Mohe City.
Mohe City is the county with the lowest temperature in China. Due to the alternating influence of continental and oceanic monsoons, the microclimate changes rapidly and local climate differences are significant. Controlled by the polar continental air masses, winter is cold, dry and long.
The annual average temperature in Mohe City is -5.5℃, and the minimum temperature is -53℃ (at 07:00 on January 22, 2023, Amul Town, Mohe City). The average monthly temperature is below 0℃ for 8 months. The annual temperature range is 49.3℃. The average frost-free period is 86.2 days. The average annual precipitation is 460.8 mm, and more than 70% of the annual precipitation is concentrated in July.
The dry season is from May to June, and the flood season is from July to August. The annual average total solar radiation is 96-107 kcal per square centimeter, and the sunshine hours are 2377-2625 hours. The accumulated temperature ≥10℃ is 1436-2062℃.
Three "extremely cold" weather conditions:
When the lowest temperature reaches below -40℃, it is called "extremely cold" weather, which can be said to be the coldest of cold. We counted the number of "extremely cold" days in all sites that entered the first two lists from 1951 to 2022. The top three were Tuli River, Mohe and Genhe.
The number of days reached 1147 days, 1052 days and 984 days respectively. This means that on average, the local area will experience extreme cold temperatures below -40°C for about half a month a year.
Most of the coldest sites in my country are concentrated in the northeastern Inner Mongolia-Daxinganling area. According to meteorological analyst Wang Weiyue, this area is one of the areas most frequently affected by cold air in my country. Multiple cold air events in winter will cause the local basic temperature to drop very low.
In addition, when cold air arrives, it will be blocked by the Greater Khingan Mountains and accumulate here, causing the temperature to drop further. In addition, this area is also a relatively high latitude area in my country. In winter, the days are short and the nights are long. It receives the least solar radiation and loses a lot of heat through outward radiation. Therefore, it has become one of the coldest areas in my country.
