Beautiful pictures of the twenty-four solar terms and autumnal equinox

Img Desc:

The autumnal equinox is the sixteenth solar term among the twenty-four solar terms of the lunar calendar. It usually falls between September 22nd and 24th in the Gregorian calendar every year.The climate in the south begins with autumn from this solar term.First, the sun reaches 180° of ecliptic longitude (the autumnal equinox) on this day. The sun almost shines directly on the earth's equator, and day and night are of equal length in all parts of the world (regardless of the refraction of sunlight by the atmosphere and the morning and evening shadows).
