This paper introduces the main characteristics of solar terms in autumn equinox.

There are three main characteristics of the autumnal equinox solar term.

The main features: the position of direct sunlight continues to move from the equator to the southern hemisphere, and the phenomenon of shorter days and longer nights in the northern hemisphere will become more and more obvious.

Main feature 2: The temperature difference between day and night will gradually increase.

Main features: the temperature drops day by day, getting colder day by day, and gradually entering the late autumn season. The situation in the southern hemisphere is just the opposite.

In the autumn equinox, most parts of China have entered a cool autumn. The cold air from the south meets the gradually decaying warm and humid air, which causes repeated precipitation and the temperature drops again and again. As people often say, it's time for an autumn rain and a cold, but the daily precipitation after the autumnal equinox will not be very large. At this time, the field farming in the south and the north is different.

202 1 introduction of sunrise time of autumnal equinox!

What time is the sunrise on the day of the autumnal equinox solar terms? Mainly depends on what area it is.

Take Beijing as an example: Beijing latitude 39? 55? 48? East longitude 1 16? 24? 0? . The sunrise time of the autumnal equinox solar term is 6: 00.

The autumnal equinox is the fourth solar term in autumn, the autumnal equinox solar term and the 16 solar term among the 24 solar terms. The autumnal equinox is when the sun reaches 180 degrees on September 23rd or 24th every year. The sun shines directly on the equator of the earth, and the day and night are equally divided, each with 12 hours. There is no extreme day and night in the world. After the autumnal equinox, the direct point of the sun continues to move southward, so the autumnal equinox is also called declination. After that, the temperature difference between day and night will gradually increase, and the amplitude will be higher than 10℃. Pay attention to dress and keep warm.
