Causes of weather explosion and cold explosion

The reason why the weather is cold is that after beginning of spring, the temperature dropped sharply due to the invasion of strong cold air. After the beginning of the solar term in beginning of spring every year, the temperature in most parts of China began to rise slowly. Meteorology, the average daily temperature for five consecutive days is higher than 10 degrees, reaching the standard of spring.

Weather introduction

According to this standard, in some years, many areas in the south have entered the spring in late February, but in the process of warming up, cold air often invades, especially in the south of the Yangtze River and along the Yangtze River. The cold air in the north meets the warm and humid air in the south, which leads to continuous rain in spring, which makes the temperature drop obviously, forming what people often say is the cold in late spring.

In meteorology, the cold in late spring usually refers to the weather phenomenon that the temperature rises rapidly in early spring, but the temperature in late spring from March to April is lower than normal. In the transitional season of winter and spring, the temperature rises gradually. After entering the spring, due to the invasion of strong cold air, the temperature often drops sharply, which is obviously lower than the normal value.

The cold in late spring is likely to cause a large area of trees and crops to freeze. The cold air gets stronger as it goes south. The wider the cooling range, the greater the possibility of catching a cold in late spring.
