Is 202 1 a solar term in beginning of spring?
1, from an astronomical point of view, beginning of spring means that it has entered the spring. The reason is that beginning of spring is the first of the 24 solar terms. Beginning of spring usually falls from February 4th to 5th on the Gregorian calendar, just within ten days before and after the Spring Festival. But just taking beginning of spring as beginning of spring is not in line with the actual weather conditions.
The second is the traditional saying. The spring of China lunar calendar is correction month, February and March. The first month in Meng Chun is called early spring, mid-spring in February and Yangchun in March. This statement is more realistic.
2. From the perspective of modern meteorology
In climatology, spring refers to the period when the temperature rises after winter (every five days), and the average temperature is between 10℃ and 22℃. In ancient times, Li Si refers to the beginning of spring, summer, autumn and winter. Its agricultural significance is spring planting, summer sowing, autumn harvest and winter storage, which summarizes the whole process of the relationship between agricultural production and climate. China has a vast territory, complicated geographical conditions, extremely different climate and different seasons. Therefore, Li Si cannot be applied to all parts of the country. It is more scientific to judge whether it is spring in the morning and evening with the average temperature as the standard.
