Mohe is the northernmost part of which climate zone in China?

Mohe County is located in the northernmost part of China, adjacent to Siberia. It is the lowest temperature county in China, with cold weather and low temperature all the year round. The temperature in winter is generally below -40℃, which is the lowest in China. The main wind direction throughout the year is northwest wind. The average temperature in Mohe County 1 month is -30.9℃, the lowest temperature in winter is only-52.3℃ ... The average temperature in July 18.4℃, and the highest temperature can reach 39.3℃ ... It belongs to the continental monsoon climate of cold temperate zone.

Due to the alternating influence of continental monsoon and maritime monsoon, the microclimate is changeable and the local climate is significantly different. Winter is controlled by the polar continental air mass, and the climate is cold, dry and long; In summer, affected by the subtropical ocean air mass, the precipitation is concentrated, the rainfall is abundant, the climate is hot and humid, and the sunshine time is long, which is suitable for the growth of cold-tolerant crops, but it is prone to floods and low temperature chilling injury. In spring and autumn, the climate is changeable due to the alternation of winter and summer monsoon. In spring, there are many strong winds, less precipitation and dry things, which are prone to forest fires; In autumn, the temperature drops suddenly, and early frost and freezing injury often occur.

The average annual temperature in Mohe County is -5.5℃. The average temperature in each month has been below 0℃ for 7 consecutive months. The annual temperature 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. May to June is the dry season, and July to August is the flood season. The annual average total solar radiation is 96 ~ 107 kcal per square centimeter, and the sunshine hours are 2377 ~ 2625 hours. Accumulated temperature ≥ 10℃ is 1436 ~ 2062℃.

Average high temperature C: (June) 24.0 (July) 25.8 (August) 23.2.

Average low temperature c: (June) 7.0 (July)11.5 (August) 9.2.

Mohe is a permafrost region. The maximum thickness of frozen soil is below 100 m, and the maximum thawing upper interface is only about 20 cm at the shallowest part of frozen soil. The survival and growth of local wild animals and plants exceed the tolerable extreme low temperature, which becomes the limiting factor. But this is a suitable temperature range for plants and animals that like low temperature and cold tolerance.
