The total temperature in Mohe County for one year.

Mohe county belongs to the continental climate of cold temperate zone, and it is the county with the lowest temperature in China. In winter, controlled by continental monsoon and Mongolian high pressure, strong cold air pushes from west to east, and precipitation drops sharply, which is extremely cold. The severe cold period is long, with the average temperature of 1 in February and 1 1 2 in February and March. When the Aleutian low pressure prevails in the Pacific Ocean, the pressure gradient between land and sea is -28℃. [9]

In spring, when the low pressure of Lake Baikal and Mongolia moves eastward through the county seat, it is the strongest season. The average wind speed in April and May is 1.8m/s, with little rain. [9]

In summer, Mohe County is located in the northeast of continental depression. When the Pacific subtropical high carries warm and humid airflow from south to north and merges with it, the temperature rises and precipitation increases. The highest temperature is in July, and the average monthly temperature is generally above 18. 1℃. Due to the complex terrain, strong solar radiation and high air humidity, it is easy to produce local small-scale convection clusters and local raindrops and thunderstorms. [9]

In autumn, the low pressure of Lake Baikal moves eastward, with frequent cold air activities and sudden drop in temperature. Frost appeared in August and September, precipitation decreased, autumn was crisp, and "Wuhua Mountain" began to appear.

Division of seasons: According to the new division standard of seasons proposed by China expert Zhang Baokun in 1934, in winter, the average temperature (the average temperature for five consecutive days) is stable below 10℃. In summer, it steadily rises above 22℃ as the beginning of summer. In spring, the average temperature rises steadily from below 10℃ to above 10℃. In autumn, the temperature drops steadily from above 22℃ to below 22℃. According to the weather and climate, Mohe County is divided into four seasons. Mohe county has a long winter, which can reach 8 months and 240 days. 1 ~ 5,10 ~1the average temperature in February is 0.3℃~ 28.7℃. Mohe has no summer, and spring and autumn are connected. The average temperature in June, July, August and September is about 7.5℃ ~ 18. 1℃, 120 days.
