What are the climate characteristics of the Vernal Equinox

On the day of the Vernal Equinox, the sun shines almost directly on the equator, and day and night are almost equal in most parts of the world. At the North Pole (90° north latitude) and Near the South Pole (90° south latitude), the special phenomenon of "the sun rotating around the horizon all day long" can be observed. After the Spring Equinox, the position of direct sunlight continues to move northward, and the days in the Northern Hemisphere begin to become longer and the nights shorter. The vernal equinox is a relatively important solar term. It not only has astronomical significance: the northern and southern hemispheres are equally divided into day and night.

At this time, the severe cold has passed, and the temperature has risen rapidly, especially in North China and the Huanghuai Plain.

In the vast land, willows are green on the banks, warblers are flying, grass grows, wheat is jointing, rapeseed flowers are fragrant, peach blossoms are red and plum blossoms are white, and spring is yellow, and South China is a scene of late spring. From the perspective of climate rules, precipitation in the south of the Yangtze River increases rapidly at this time, entering the spring "peach blossom flood" period; in the vast areas of Northeast, North China and Northwest China where "spring rain is as expensive as oil", precipitation is still very little, and the threat of spring drought is the key to agricultural production. the main problem.
