Brief introduction to the characteristics of vernal equinox solar terms What are the characteristics of vernal equinox solar terms?

1. On the vernal equinox, the northern and southern hemispheres share the day and night equally, that is to say, day and night are the same in almost all parts of the world.

2. During the vernal equinox, the East Asian trough is obviously weakened, and the ridge activity in the westerly belt is obviously enhanced. In windy and dusty weather in the north, when the long wave trough moves eastward, there will be continuous rainy and low temperature weather in late spring.

3. During the spring equinox, the temperature rose rapidly, and the daily average temperature in most parts of China rose steadily to above 0℃.

4. The precipitation in the south is increasing rapidly, but there are few in the northeast, north China and northwest, so crops should resist spring drought.
