How many months are there in winter in Northeast China?

The latitude in Northeast China is relatively high, mainly in the middle temperate zone, which belongs to the temperate monsoon climate. Winter is cold and long, and it is in winter for about 6 months all year round. Crops are harvested once a year, and the sunshine time in summer is longer than that in the south, which is another advantage of agricultural development in this area.

Northeast China spans the middle temperate zone and the cold temperate zone from south to north, with four distinct seasons, warm and rainy summer and cold and dry winter. From southeast to northwest, the annual precipitation decreases from 1000 mm to below 300 mm, and it transits from humid area and semi-humid area to semi-arid area. The high forest coverage in Northeast China can prolong the melting time of ice and snow, and forest snow storage is helpful to the development of agriculture and forestry.

Extended data:

Due to the high latitude, small solar altitude angle, short daytime in winter and close to the birthplace of winter wind, Northeast China is obviously affected by winter wind, so it is cold in winter, with more snowfall and less evaporation. In spring, the snow melts, and there is a spring flood in the river, which is conducive to sowing crops in spring, so the spring drought is lighter than that in North China, and the river water volume is also large.

In addition, the terrain here is relatively flat, the water flow is gentle, the vegetation coverage rate is high, and the river sediment concentration is smaller than that in North China. The rivers in Northeast China have a long ice age, and Heilongjiang is the longest river in the ice age. Because of the low terrain and low evaporation, there are many swamps and wetlands, such as Sanjiang Plain. Now the country is making great efforts to protect and no longer develop the "Great Northern Wilderness".
