The climate in the south also enters autumn in the autumnal equinox, so it will not be hot after the autumnal equinox in 2020.

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 great.

At this time, the field farming in the south and the north is different. In northern China, there is an agricultural proverb that says: "The white dew is early, the cold dew is late, and it is the right time to plant wheat in the autumn equinox." Proverbs clearly stipulate the sowing time of winter wheat in this area; And "White clouds come in autumn equinox, good songs and good rice seeds are everywhere" reflects the planting time of rice in Jiangnan area. In addition, the working people's taboos on the autumnal equinox solar terms are also summarized as proverbs, such as "The autumnal equinox is only afraid of lightning, how much is it?"

At the autumnal equinox, the Yangtze River basin and its vast northern area have entered autumn, and the daily average temperature has dropped below 22℃. The cold air mass in the north began to have some influence. In most areas, the rainy season has just ended, with a cool breeze and clear skies and beautiful Wan Li. Guangdong and Hainan will not get cold until the end of 10 to10.

After the autumnal equinox, the direct sunlight moved to the southern hemisphere, and the northern hemisphere got less and less solar radiation, but the ground lost more heat and the temperature dropped significantly. The agricultural proverb says, "an autumn rain and a cold".

Will the days get shorter after the autumnal equinox?

On the day of the autumnal equinox, the day is as long as the night, which is twelve hours. From this day on, the days are getting shorter and shorter. This is the vernal equinox solar term. Autumn is 90 days, and it is divided into two halves at the equinox, with 45 days before and after. After the autumnal equinox, the direct sunlight moved to the southern hemisphere, and the northern hemisphere got less and less solar radiation, while the ground lost more heat and the temperature dropped significantly. So it will cool down soon after the autumnal equinox.
