When this circulation is adjusted, there will often be a wide range of rain and snow weather and strong winds to cool down. When the west of 80 degrees east longitude is a long wave ridge and East Asia is a coastal trough, under the influence of the northwest wind and the constantly supplemented cold air, China will have a sustained low temperature. In some parts of China, severe cold is not as cold as slight cold, but in the southern coastal areas of China, the lowest temperature in a year appears in the severe cold solar terms.
