extended information

on the day of the vernal equinox, the sun is almost directly at the equator of the earth, and the whole world is almost as long as day and night. After the vernal equinox, the direct point of the sun began to enter the northern hemisphere, and the days began to be long and the nights were short in all parts of the northern hemisphere.

The vernal equinox is an important solar term, which not only has astronomical significance: the northern and southern hemispheres are equally divided day and night, but also has obvious characteristics in climate. During the vernal equinox, China enters a bright spring except the Qinghai-Tibet Plateau, the northeast, the northwest and the northern part of North China. On the vast land, willows are green, yingfei grass grows, wheat jointing and rape blossoms.

Air pressure

During the solar terms in the vernal equinox, the East Asian trough is obviously weakened, and the trough ridge activity in the westerly belt is obviously increased. From Mongolia to the northeast, there are often low-pressure activities and cyclones, and the low-pressure movement leads cold air to the south, and there are windy and sand-blowing weather in the north. When the long wave trough moves eastward, it will appear continuous rainy and cold weather due to the intersection of cold and warm air masses.
