The winter solstice in 2022 is on February 22, 65438. On this day, there will be an extreme night phenomenon in many parts of the northern hemisphere, that is, the sun will not rise for a while. In the southern hemisphere, the situation is just the opposite. The sun will be high in the sky and the days will be unusually long.

Meteorological changes in winter solstice

First of all, the obvious drop in temperature is the most significant meteorological change from winter solstice to Sunday. As the direct point of the sun moves south, the solar radiation energy received by the northern hemisphere is greatly reduced, resulting in a sudden drop in temperature. In many areas, the solstice around winter is the coldest time of the year, and cold waves and snow and ice weather frequently appear.

Secondly, precipitation has also decreased. As the temperature drops, the probability that water vapor in the air condenses into snowflakes increases, so there may be heavy snow and other snowfall weather in the northern region during the winter solstice. The southern region may become dry, and the precipitation is mainly in the form of rain or frost.

In addition, during the winter solstice, the stability of the atmosphere is enhanced and the wind is gradually weakened. In many places, the wind direction in winter is mainly north wind and northwest wind, and the wind force is relatively strong. But with the arrival of the winter solstice, the wind gradually weakened and the atmosphere became more stable.
