Temperature changes in rainy season

China has many solar terms. I believe many of my friends were asked by their teachers to recite twenty-four solar term song when they were young. Every solar term has a special meaning. Among them, Grain Rain is the last solar term in spring. With the arrival of Grain Rain, the temperature will change greatly. The most obvious change is that the temperature is no longer cold, and the temperature gradually rises.

First of all, the temperature will gradually warm up. It will be rainy before and after Grain Rain, and the humidity in the air will increase, which is more suitable for the growth of crops. Especially in the south of China and the middle and lower reaches of the Yangtze River, precipitation can increase significantly. After the weather gets warmer, many flowers are in bud and competing for beauty. In the south, you can see flowering peonies, red ripe cherries and flying catkins.

Secondly, after Grain Rain, the weather began to feel hot. The climate temperature in many areas is slowly approaching 30 degrees. For example, in eastern South China, there is often a high temperature of more than 30 degrees for a day or two, and there are low-altitude river valleys, which also enter summer early. In South China, after Grain Rain, there will be rainy weather for a long time, which may even cause local heavy rain and torrential rain, which may enter the first flood season of each year and even bring natural disasters such as thunderstorms and hail. In some areas, after the Grain Rain season, there will be terrible natural disasters such as landslides and mudslides. In the north, the solar term Grain Rain symbolizes? Final cream? .

Finally, as the last solar term in spring, Grain Rain is a solar term that many people like very much, because the arrival of this solar term means the arrival of the rainy season, and crops can thrive. Precipitation at this time is particularly important for the growth of rural crops. I believe everyone has heard of it, right? Spring rain is as expensive as oil? This metaphor.

In Grain Rain season, the temperature and air humidity in most inland areas of China increase obviously. There will be the first heavy rain in many areas, and the precipitation can basically reach about 50 mm, which is very beneficial to rice-growing areas.
