fall equinox fall equinox，"Divided" means "tied"、"Half" means，On the autumnal equinox, the sun's rays hit the Earth's equator almost directly，Day and night equals around the globe。After the autumnal equinox，The direct solar point continues from the equator towards the southern hemisphere，Days begin to grow shorter throughout the Northern Hemisphere，That is, within a day, the day begins to be shorter than the night；The Southern Hemisphere is the opposite。After the autumnal equinox, the direct position of the Sun shifts to the Southern Hemisphere，The Northern Hemisphere receives less and less solar radiation，The ground loses more heat，The rate of temperature reduction has accelerated significantly。It's the autumnal equinox，The heat has subsided，The weather is getting cooler，Summer is cool。
