Influence of Cold Wave on Agricultural Production and Traditional Dwellings in Northeast China

The source of cold wave is the source of winter wind. The cold wave comes from Mongolia and Siberia. The northeast latitude is relatively high, which is close to the source of cold wave. Due to the influence of the cold wave, the temperature drops greatly in winter and the climate is very cold. Crops in Northeast China are very sad in winter because of climate, so wheat, rape and so on are all spring sowing crops. Crops can only be harvested once a year, and cold waves may bring freezing damage. Affected by the climate, the walls of traditional houses in Northeast China are very thick, and there are interlayers in the walls as firewalls. The window is equipped with multiple layers of glass; The roof has a steep slope, which makes it easier for snow to slide down when it snows.
