Will it snow after the beginning of spring? Why does it snow after the beginning of spring?

In the beginning of spring, the southern branch of the westerly jet stream in East Asia has begun to weaken, and the midwinter climate is about to end. However, the intensity and position of the northern branch of the westerly jet stream have basically not changed. The Mongolian cold high pressure and the Aleutian low pressure are still relatively strong, and strong winds and cooling are still the main weather conditions. So, will it snow after the beginning of spring? Why does it snow after the beginning of spring? Now, with these questions, let's take a look at the introduction of Encyclopedia Knowledge Network!

Will it snow after the beginning of spring?

The snow after the beginning of spring is also called spring snow.

Snow has a wide range of functions, but it is of great benefit to humans. First of all, it is beneficial to the growth and development of crops. Because snow has poor thermal conductivity, a layer of snow covering the soil surface can reduce the outward transfer of soil heat and block the invasion of cold air on the snow surface. Therefore, crops protected by snow can safely survive the winter. Snow accumulation can also store water for crops. In addition, snow can enhance soil fertility. According to measurements, about 7.5 grams of nitrogen compounds are contained in every liter of snow water. When snow water seeps into the soil, it is equivalent to applying nitrogen fertilizer once. Using snow water to feed livestock and poultry and irrigate crops can bring obvious benefits.

Snow can be beneficial to people, but also harmful. In the mid-spring season of March or April, if a sudden cold wave causes heavy snow, it will cause freezing. Therefore, the farmer's proverb says: "Winter snow is a treasure, spring snow is not good."

Why does it snow after the beginning of spring?

The Beginning of Spring is just a term for the solar terms. It is more practical for the Jiangnan region. For the north, it is still winter and has not yet entered spring. Spring will not come until late March.

Climate characteristics of Lichun

After the beginning of spring, the temperature rises and the busy spring farming season begins in most parts of the country. At the beginning of spring, the southern branch of the westerly jet stream in East Asia has begun to weaken, and the midwinter climate is about to end. However, the intensity and position of the northern branch of the westerly jet stream have basically not changed. The Mongolian cold high pressure and the Aleutian low pressure are still relatively strong, and strong winds and cooling are still the main weather conditions.

However, during the intervals between the influence of strong cold air, the frequency of southerly winds increased, accompanied by a significant rise in temperature.
