Characteristics of solar terms in autumnal equinox
The autumnal equinox solar terms are the solar terms that transition from early autumn to late autumn. By this solar term, most parts of the country have begun to enter the cool autumn. The cold air in the south meets the gradually decaying warm and humid air, and the rainfall will take away the heat on the ground and lower the surface temperature. Therefore, after the autumnal equinox, the weather will gradually cool down and the temperature difference at night will gradually widen.
After the autumnal equinox, the direct point of the sun began to enter the southern hemisphere from the equator, and the northern hemisphere began to have shorter days and longer nights, and the day began to be shorter than the night in a day. The autumnal equinox solar term is located on the ninetieth day of autumn, in the middle of autumn, which means to divide autumn equally. At the autumn equinox, the sun reaches longitude 180 (autumn equinox).
Almost directly to the equator of the earth, day and night are the same in the world, and then the day will be obviously shortened, and the evening will be gradually extended, and the climate will become much more comfortable.
