The origin of vernal equinox
The vernal equinox is the midpoint of 90 days in spring, when the sun is at 0 (vernal equinox) of the yellow meridian. On the vernal equinox, the sun shines directly at the equator of the earth, and the seasons in the northern and southern hemispheres are opposite. The northern hemisphere is the vernal equinox and the southern hemisphere is the autumnal equinox.
Twenty-four solar terms: "in mid-February, half a minute, that is, half of 90 days, so it is called minutes." Autumn is synonymous. " "Spring and Autumn Stories Yin and Yang in and out" said: "The vernal equinox, Yin and Yang are also half-phase, so it is cold and summer day and night."
Weather and climate
On the day of the vernal equinox, the sun is almost direct to the equator, and day and night are almost equal in most parts of the world. After the vernal equinox, the direct sunlight position continues to move northward, and the days in the northern hemisphere are long and the nights are short. 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, except the Qinghai-Tibet Plateau, the northeast, the northwest and the northern part of North China, China has entered a bright spring, and on the vast land, willows are green, Fei Ying grass grows, wheat jointing and rape blossoms are fragrant.
