Where does the sun shine directly during the autumnal equinox?

On the day of the autumnal equinox, the sun reaches 180° of ecliptic longitude (the autumnal equinox point), almost directly shining on the earth's equator, and the day and night are equal in length everywhere in the world . <br /> After the autumnal equinox, the sun's direct point continues to move from the equator to the southern hemisphere, and the days begin to become shorter and the nights longer in various parts of the northern hemisphere, that is, the day begins to be shorter than the night within a day; the opposite is true in the southern hemisphere. Therefore, the autumnal equinox is also called the autumnal equinox. At the North and South Poles, on the day of the autumnal equinox, the sun stays above the horizon all day. After that, as the sun's direct point continues to move south, a six-month polar night begins near the North Pole, gradually expanding and then shrinking in scope; a six-month polar day begins near the South Pole, gradually expanding and then shrinking in scope. Geography (1) Winter Solstice - 12/22 On the winter solstice, the sun is directly above the Tropic of Capricorn, and the daylight hours are the shortest in the northern hemisphere. Then the sun's direct point begins to move northward, and the daylight hours in the northern hemisphere become longer and longer.
(2) Spring Equinox - 03/21 After the Spring Equinox, the sun's direct point moves to the Northern Hemisphere, and the days in the Northern Hemisphere begin to be longer than the nights.
(3) Summer Solstice - 06/22 On the Summer Solstice, the sun is directly above the Tropic of Cancer, and the daylight hours are longest in all parts of the Northern Hemisphere. Then the sun's direct point begins to move southward, and the daylight hours become shorter and shorter in all parts of the Northern Hemisphere.
(4) Autumnal Equinox - 09/23 After the Autumnal Equinox, the sun's direct point moves to the Southern Hemisphere, and the days in the Northern Hemisphere begin to become shorter than the nights.

What happens if it doesn’t rain on the Autumnal Equinox?

Answer: The Autumnal Equinox is the busy farming season, so it is naturally best if it does not rain at this time.
Why is it better not to rain during the Autumnal Equinox?
Because of the rapid drop in temperature in autumn, the busy season of autumn harvest, autumn plowing and autumn planting seems particularly intense. During the Autumnal Equinox, cotton bolls appear and tobacco leaves turn from green to yellow, which is a good time to harvest. Winter wheat sowing has begun in North China, and the Yangtze River Basin and vast areas in the south are busy harvesting late rice, plowing the land when the weather is sunny, and preparing for rapeseed sowing. Drought, little rain or continuous rain during the autumnal equinox is the main unfavorable factor affecting the normal progress of the "three autumns". In particular, continuous rain can cause the crops that are about to be harvested to fall over, rot or sprout, causing serious losses. The key to the busy three autumns is to start early. Timely harvesting of autumn crops can prevent the damage of early frost and continuous rain. Timely early sowing of winter crops can make full use of the heat resources before winter, cultivate strong seedlings to safely overwinter, and lay the foundation for a good harvest in the coming year. "If the double-season late rice does not emerge by the Autumnal Equinox, it will be harvested and fed to the cows." The double-season late rice in the south is heading and flowering, which is a critical period for yield formation. The "Autumnal Equinox cold" weather caused by early low temperature and rain is the main threat to the flowering and fruiting of the double-season late rice, so farmers at this time must carefully carry out forecasting and prevention work.
