When is the solstice in winter?

65438+February 22nd, 2023 is the winter solstice.

Winter solstice, also known as solstice, winter festival, child year, etc. It has both natural and humanistic connotations. It is not only an important solar term among the 24 solar terms, but also a traditional folk ancestor worship festival in China. In winter, the Gregorian calendar is 65438+February 2 1-23 every year, and the winter solstice in 2023 is 65438+February 22.

The winter solstice, known as the "southern solstice", is a solar term reflecting the direct sunlight movement. On the winter solstice, the sun goes south to the extreme, and the sun shines directly on the tropic of Capricorn. Since the winter solstice, the direct point of the sun has returned to the north. The solstice in winter is the turning point of "going south to north". Since then, the sun has risen in height and the days in the northern hemisphere have increased day by day. The solstice in winter marks the rebirth of the sun and the round-trip movement of the sun into a new cycle. The solstice in winter is an auspicious day. After the solstice in winter, the days are getting longer and longer and the sun is rising. This is the beginning of a round-trip cycle directly pointed by the sun, which should be celebrated.

Meteorological changes in winter solstice

From winter to the future, although the solar altitude angle gradually increases, it is a slow recovery process, and the heat lost every day is still greater than the heat received, showing a situation of "making ends meet".

After the winter solstice, the climate in all parts of China will enter a coldest stage, which is often called "ninth year cold" and "ninth year cold". The so-called "counting nine" means counting from the winter solstice (and in some places from the winter solstice), counting "nine" every nine days, and so on; Count to nine, until the eighty-first day, when the peach blossoms opened, the chill disappeared.

Although the days from winter solstice are short, the temperature from winter solstice is not the lowest; It won't be very cold before the winter solstice, because there is still "accumulated heat" on the surface, and the real cold winter is after the winter solstice. Due to the disparity of climate in different parts of China, this astronomical climate feature is obviously late for most parts of China.
