When is the solar term?

The annual solar term of "Sting" usually starts on March 5th or 6th and ends on March19th or 20th. During this period, the two sides of the Yangtze River have successively entered the real spring from west to east, that is, it has reached the standard that the Central Meteorological Observatory generally divides spring according to the daily average temperature: the daily average temperature for five consecutive days is ≥10℃ ~ ≤ 22℃; At this time, South China is already a scene of "peach blossom red, plum blossom white, orioles singing and swallows coming"; On March 4, 2006, the ninth "Ninth Five-Year Plan" began. As the saying goes, "Nine plus nineteen, plowing cattle everywhere", people in the Weishui River basin and the middle and lower reaches of the Yellow River began to accumulate fertilizer, loosen soil and plow fields. "Nine flowers bloom, and farm work comes together." During the dormant period, the upper-air circulation in East Asia initially completed the situation adjustment, showing the characteristics of the turning point in spring. The weather system that affects our country is like a passer-by. Cold and warm air alternates frequently, and cold air shows strength, and sometimes it drives straight in. Warm air keeps pace with the times and becomes more and more powerful. The two men took turns to appear and staged a short play with alternating cold and warm, sunny rain and snow.

The weather at this time: it's already a moonlit night in the south. In this spring morning when I woke up, birds were singing everywhere, but now I still remember that night, the storm and I don't know how many flowers were broken, but the rainy weather has begun to increase at this time; The north is dry and windy, sometimes accompanied by dusty weather. There is a proverb that says, "It's a surprise to blow the north wind and spend the winter from the beginning". It can be seen that the early spring is warm and cold, and the temperature is high and low. If there is strong cold air going south, crops in the south will sometimes be attacked by "low temperature and rainy weather".
