What are the climatic characteristics of the autumnal equinox?

Climatic characteristics of autumnal equinox: one autumn rain and one cold.

As the agricultural proverb goes, an autumn rain is cold, and the white dew is divided into nights, and it is cold all night.

In August, the wild goose gate opens, and frost comes to the foot of the wild goose. It is not surprising that frost appears in the autumn equinox in the years when the temperature in Northeast China drops earlier.

On the day of the autumnal equinox, the sun is located at the longitude of the yellow meridian 180 degrees, and the sunlight is almost direct to the equator, and the length of day and night in most parts of the world is almost the same.

At this time, the waiting temperature in the southern region has generally dropped below 22℃, and it has entered a cool autumn. An autumn rain and a cold.

The cold air from the south meets the warm and humid air that gradually decays, resulting in repeated rainfall and the temperature dropping again and again.

In the northern part of the northwest plateau, the daily minimum temperature has dropped below 0℃, and you can already see the magnificent snow scene flying all over the sky and the earth wrapped in silver.

Since the autumnal equinox, the climate has two main characteristics:

(1) The position of direct sunlight continues to move from the equator to the southern hemisphere, and the day in the northern hemisphere is shorter than the night until the winter solstice reaches the shortest day.

(2) The temperature difference between day and night gradually increases. The temperature drops day by day, getting colder every day, and gradually entering the late autumn season. The situation in the southern hemisphere is just the opposite. How about getting married in the autumn equinox in 2020?

Calculation of solar term date by mean time of autumnal equinox;

Calculation formula: [y? D+C]-L

Interpretation of the formula: Y= the last two digits of years, D=0.2422, L= leap years, 2 1 century C=23.042, and 20th century =23.822.

For example: autumnal equinox date in 2088 =[88? 0.2422+23.042]-[88/4]=44-22=22, and September 22nd is the autumnal equinox.

Exception: 1942 plus 1 day.
