Causes of Cold and Humid Climate in Northeast China
1, high latitude: the three northeastern provinces are located between 40 and 50 north latitude, and the direct point of the sun is located in the southern hemisphere. The height of the sun in Northeast China is small, and the atmospheric distance through which solar radiation passes is long, which has a strong weakening effect on solar radiation, and less solar radiation reaches the ground. Also, because the solar altitude angle is small, the same amount of solar radiation reaches the ground and spreads to a larger area, and the solar radiation per unit area is less and colder.
2. Winter days are short and nights are long: winter is half a year, and days are short and nights are long in the northern hemisphere. The higher the latitude, the shorter the day and the longer the night, the less solar radiation you get.
3. Winter is controlled by cold air masses: In winter, northeast China is controlled by cold air masses originating from Mongolia and Siberia, northwest monsoon prevails, and the weather is cold and dry.
