Is solstice in beginning of winter the same day as winter?

Not on the same day, but it is one of the 24 solar terms. In early winter, it is usually around 1 1.7, and the winter solstice is around 1.22.

After beginning of winter, the sunshine time will continue to shorten, and the height of the sun will continue to decrease at noon. In winter, northeast winds and north winds prevail, and the temperature drops gradually. Because there is still some energy in the heat stored on the surface, it is generally not very cold in early winter.

As time goes by, strong cold air frequently goes south and crosses Nanling, and the weather is getting colder and colder. In the north, it is already very cold before winter begins. Beginning of winter means that anger begins to close and everything enters a state of recuperation. Its climate has also changed from dry autumn to rainy and cold winter.

Extended data:

Westerly jet at high altitude after early winter has been completely established in South Asia. At this time, the fluctuation intensity and eastward movement of the south branch of the high-altitude westerly wind. As the northwest, north China, northeast China and other places that have already entered winter, it can be said that the wind cooling at this time can be used to it.

If it encounters strong and fast cold air, it will travel to running all the way, which will increase the wind power in the northern Shankou area and the southern rivers and lakes, and the wind will blow all the way to the southeast coast and the Taiwan Province Strait. The typical continuous rain in West China in Southwest China has ended, but compared with the situation of little rain in the whole country, it is still a rainy place.

The rainfall in Sichuan Basin, eastern Guizhou and southwestern Yunnan in June 5438+065438+ 10 exceeded 50 mm. In Yunnan, sunny days are warm, rainy days are cold, and there is a saying that "the four seasons are like spring and it rains in winter". If there is strong cold air invasion and warm and humid air flow echoes, the process rainfall in the southern region will be greater.
