What is the date of spring?

Generally, when the sun reaches 3 15 degrees on February 3rd (or 4th and 5th) of the lunar calendar every year, it is beginning of spring.

The division of beginning of spring:

1. Since the Qin Dynasty, China has always regarded beginning of spring as the beginning of spring. Beginning of spring is divided from astronomy, but in nature and people's minds, spring is warm and flowers are fragrant. Spring is growth, cultivation and sowing. In climatology, spring refers to the period when the average temperature is between 10℃ and 22℃.

2. The dividing line between beginning of spring and China in winter and spring (when the average temperature reaches 65,438+00 degrees Celsius for five consecutive days, it is regarded as spring), from Guilin, Guangxi to Ganzhou, Jiangxi. In the area south of this line, beginning of spring sometimes smells like spring, but 93% of the land in China is still winter, while in Heilongjiang, it is often long summer and spring, and in Grain Rain. The so-called beginning of spring is just a "conception".

Climate change in early spring;

1, beginning of spring is not only the first of the 24 solar terms, but in nature and people's minds, spring means warm weather, flowers and birds, and everything grows and seeds are sown in spring. The so-called "one year's plan lies in spring".

2. In climatology, spring refers to the period when the average temperature is between 10℃ and 22℃. Speaking of beginning of spring, people obviously feel that the days are getting longer and the sun is getting warmer. Temperature, sunshine and rainfall are often at the turning point of the year and tend to rise or increase.

3. beginning of spring solar terms, westerly jet, the southern branch of East Asia, began to weaken, and the winter climate was coming to an end. However, the intensity and location of the northern branch of westerly jet remain basically the same, the Mongolian cold high and Aleutian low are still relatively strong, and gale cooling is still the prevailing main weather. However, during the intermission under the influence of strong cold air, the frequency of southerly winds increases, accompanied by an obvious warming process.
