What are the solar terms after the Millennium?

After the Millennium is the autumnal equinox solar terms.

The Millennium and the autumnal equinox are both obvious. They describe the weather and the surrounding climate. At this time, the temperature difference and rainfall around can be clearly observed.

At this time of the Millennium, Xia Feng is gradually replaced by the winter wind, and the weather is getting colder and colder. Coupled with the direct point of the sun moving south to the northern hemisphere, the sunshine time is shortened and the light intensity is weakened, gradually forming a unique climate of this season. According to the explanation of "white dew" in the twenty-four solar terms-"water and soil condense dew, autumn belongs to gold, golden white and white dew, and qi begins to be cold".

The autumnal equinox is the sixteenth solar term in the twenty-four solar terms of the lunar calendar, usually on September 22-24 of the Gregorian calendar every year. The climate in the south began to decline from this solar term. The autumnal equinox means "equally divided" and "equally divided", which means equally dividing autumn except day and night. After the autumnal equinox, the position of direct sunlight moves south, and the days in the northern hemisphere become shorter, the nights become longer, the temperature difference between day and night increases, and the temperature drops day by day.

Climatic characteristics of autumnal equinox

After the autumnal equinox, as the sun moves south, the nights are long and the days are short, and the solar radiation energy received by the ground decreases. The arrival of the autumnal equinox means officially entering autumn. As the saying goes, "one autumn rain is cold, and ten autumn rains are good for wearing cotton." By this solar term, most parts of China have begun to enter the cool autumn.

When the cold air from the south meets the gradually decaying warm and humid air, the rainfall will take away the heat on the ground and lower the surface temperature. Therefore, after the autumnal equinox, the weather will gradually turn cold, and the temperature difference at night will gradually widen. It is autumn in the Yangtze River valley and the vast area north of China, and the daily average temperature has dropped below 22℃, so the cold air mass in the north has begun to have a certain influence.

The rainy season has just ended in most areas, with clear skies and crisp autumn in Wan Li. In the northern part of the northwest plateau, the daily minimum temperature dropped below 0℃, and snowfall began. Rainfall in most parts of the south has decreased significantly, and heavy rain and heavy rain are rare; However, rainy days increase, rainy days are frequent, and the night rain rate is high.
