Isn't it cold in the solar terms and heavy snow?

"Snow does not freeze, people do not wake up" is a natural law summed up by the working people in thousands of years of long-term production and labor, and it is the crystallization of the wisdom of the working people. This means that if the local weather is still warm when the solar term of heavy snow comes, there will probably be cold weather at the end of next spring.

Causes of late spring cold

Late spring cold is a common weather phenomenon, not only in China, but also in Japan, North Korea, India and the United States. The reason is not complicated. Generally speaking, when the ten-day average temperature is more than 2℃ lower than normal, there will be more serious late spring cold. The later the cold air goes south, the stronger it becomes, the wider the cooling range, and the greater the possibility of cold in spring.

In meteorology, spring is the season with the greatest changes in meteorological elements such as temperature, airflow and air pressure. Entering March means the beginning of spring, and the temperature rises rapidly. The real average temperature in spring should exceed 10℃.

The climate in spring is changeable. Although it is gradually warming up, it is still cold in the morning and evening, and the number of cold air activities is also frequent. Long-term rainy weather or frequent cold air attacks, or under the control of continuous cold and high pressure, strong radiation cooling on sunny nights will lead to the temperature drop. If the cold air is strong, the temperature will drop sharply below 10℃, and even rain and snow will occur, thus forming the phenomenon of "late spring cold".
