On February 4, it will start spring, but now it seems that there is still heavy snow in the north. Will it snow after spring? Will the weather change after spring? What are the precautions for health care after spring?
Will it snow after spring?
The snow after spring is also called spring snow.
Snow has a wide range of functions, but it is good for human beings. First, it is conducive to the growth and development of crops. Because of the poor heat conduction ability of snow, covering a layer of snow quilt on the soil surface can reduce the heat transfer of the soil and prevent the invasion of cold air on the snow surface. Therefore, crops protected by snow can survive the winter safely. Snow also stores water for crops. In addition, snow can improve soil fertility. According to the determination, about 7.5G nitrides are contained in every 1L of snow water. When snow water seeps into the soil, it is equal to applying nitrogen once. Using snow water to feed livestock and poultry, irrigating crops can get obvious benefits.
Snow is good for people and bad for people. In the mid spring of March and April, it suddenly snowed because of the cold wave. It will cause freezing cold. Therefore, the saying goes: 'wax snow is a treasure, but spring snow is not good. '
Why does it snow after spring?
Spring is just a solar term. It's more practical for Jiangnan. For the north, it's still in winter, not in spring. It's in late March.
Climatic characteristics of spring
After the beginning of spring, the temperature picked up, and spring ploughing season began in most parts of the country. In the spring solar term, the westerly jet in the South Branch of East Asia has begun to weaken, and the winter climate is coming to an end. However, the intensity and location of the westerly jet in the North Branch have not changed. The Mongolia cold high and Aleutian low are still relatively strong, and the gale cooling is still the main prevailing weather.
However, in the interval of strong cold air, the frequency of southerly wind increases, accompanied by an obvious temperature rise process.
