What is the standard of entering spring in meteorology?

The meteorological criterion for entering spring is that the daily average temperature exceeds 10℃ for five consecutive days.

From the climate point of view, beginning of spring is just a prelude to spring. According to climate standards, Tomb-Sweeping Day in the northeast and northwest enters spring, the vernal equinox and solar terms in North China enter spring, the middle and lower reaches of the Yangtze River enter spring before and after the shock, and the rain in the southwest enters spring. Only in the south of China, the beginning of spring solar term can be used as the beginning of spring.

Meteorology is a subject that takes the atmosphere as the research object, explains the gas characteristics of large-scale agricultural meteorology from both qualitative and quantitative aspects, and focuses on the weather situation and changing law of the atmosphere and weather forecast. Meteorology is a branch of atmospheric science.

Spring, also known as spring, is the first of the four seasons, which refers to the period from beginning of spring to long summer, including solar terms such as beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain. This is the season when everything comes back to life. The Gregorian calendar in the northern hemisphere is March-May, and in the southern hemisphere (such as Australia) it is September-165438+ 10. In meteorology, the beginning of spring is that the average temperature is above 10℃ for five consecutive days. In spring, the climate is warm and mild, and there is rain in most inland areas of China, where everything germinates and the climate is changeable.
