Which of the three northeastern provinces is the coldest?

The coldest place among the three northeastern provinces is Mohe City.

Mohe is the city with the lowest temperature in the country and has a cold temperate continental monsoon climate. Due to the alternating influence of continental and oceanic monsoons, the microclimate changes rapidly and local climate differences are significant. Under the control of polar continental air masses, the climate is cold, dry and long in winter;

In summer, affected by subtropical oceanic air masses, precipitation is concentrated, abundant rainfall, hot and humid climate, and long sunshine hours, suitable for the growth of cold-tolerant crops, but It is prone to floods and low temperature damage; in spring and autumn, the climate is changeable due to the alternation of winter and summer monsoons. In spring, there are strong winds, less precipitation, and dry and dry conditions, making forest fires easy to occur; in autumn, the temperature drops sharply, and early frost and freezing damage often occur.

The annual average temperature in Mohe City is -5.5℃. 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 to 107 kcal per square centimeter, and the sunshine hours are 2377 to 2625 hours. The accumulated temperature ≥10℃ is 1436~2062℃.

Mohe is a perennial frozen soil area. The thickest frozen soil is less than 100 meters. Where the frozen soil is the shallowest, the maximum upper boundary of thawing is only about 20 centimeters. The survival and growth of local wild animals and plants exceed the tolerable low temperature extremes and become a limiting factor. But for cold-tolerant animals and plants that like low temperatures, the temperature range is suitable. ?

Mohe City topography:

The spatial distribution and natural differentiation of Mohe City landform types are not affected by the Mesozoic and its early barrier structures. control. The two do not coincide. The same geomorphological unit spans several Mesozoic tectonic zones. Mohe City is located in the northern part of the Greater Khingan Mountains and belongs to an inland mountainous area with continuous mountains, crisscrossing ravines, flat mountain tops and open valleys. The landform formation type is mainly structure-erosion topography, accompanied by structure-denudation topography and denudation-accumulation topography.

A series of mountains in the mountainous area of ??Mohe City are composed of ridges, ridges and alpine platforms with different directions and sizes. Most of them belong to low mountain and hilly areas. Its landform type can be divided into three zones from south to north. The south is a mid-mountain zone, the middle is a low mountain and hilly zone, and the north is a plain and hilly zone along the river.

The terrain of Mohe City is high in the south and low in the north, with a downward slope trend from north to south. The east and west wings are convex and symmetrical. In the north, the long beam along the north side of Nenmo Highway is also bulging. The center is lower in the area around Xilinji Town, and the lowest point in the city is in the northeast, located at the mouth of the Emul River in Xing'an Township. The highest point is Mount Baikaru in the southeast.

The southern mid-mountain zone is distributed in the upper reaches of the Amur River, Laochao River, and Dalin River, with an average altitude of 1,000 meters. The highest point, Baikalu Mountain, is located in the southeastern part of the territory, with a height of 1,397 meters; in the north, the average altitude is 600 meters meters; the average altitude in the east and west is 800 meters; the average altitude in the middle is 600 meters; the lowest altitude in the northeast is 200 meters. The city's landform trend is bulging on all sides, surrounding an oasis in the middle.
