Based on the changes in winter monsoon (wind direction and force), let me talk about the impact of winter monsoon on the climate of northern China~Thank you~

The reason for the formation of the winter monsoon is that the specific heat capacity of the land is smaller than that of the ocean, and it heats up and cools down faster. Therefore, in winter, the ocean is warmer than the continent and the air pressure is lower than the continent, so it will form. Winds blowing from high pressure (Asian continent) to low pressure (North Pacific Ocean).

Therefore, the prevailing wind direction in winter is: northwest wind in northern China and northern and central Japan. The wind is weak, but when it develops strongly, it will bring cold wave weather and the temperature will drop sharply, which will affect northern my country. Causes effects such as dryness, strong winds, and cooling.

From the perspective of atmospheric sources, since the winter monsoon that affects our country mainly comes from the cold Siberia and Mongolia in the north of the Eurasian continent, the airflow brought by the winter monsoon is cold and dry, affecting most parts of northern my country. One of the main reasons for the large temperature difference between north and south in winter.
