Correlation between Winter Solstice Weather and Spring Festival Weather

The weather from winter to Sunday has nothing to do with the weather during the Spring Festival.

The winter solstice is usually in 65438+February or 65438+1October every year, which marks the beginning of winter. The temperature drops gradually and the weather is cold and dry. The Spring Festival is usually on the first day of the first month of each year, which marks the beginning of spring. The temperature rises gradually and the weather is warm and humid.

From the climatological point of view, the weather changes from winter solstice to Spring Festival are related to atmospheric circulation and climate change. In the atmospheric circulation, frequent cold air activities in winter lead to climate characteristics such as temperature drop, wind strength increase and precipitation decrease. In spring, with the heating materials gradually occupying the dominant position, the climate characteristics such as rising temperature, weakening wind and increasing precipitation gradually appear.

In most parts of China, the weather changes during the winter solstice and the Spring Festival also show the above characteristics. For example, in the northern region, during the winter solstice, the temperature drops sharply and snowflakes fly, while during the Spring Festival, the temperature rises gradually and the spring rain continues. In the southern region, although the winter solstice temperature is not as low as that in the northern region, it is relatively cold compared with other seasons, and during the Spring Festival, the temperature rises rapidly and there are more spring rains.

However, it should be noted that climate change is a complex process and is influenced by many factors. Therefore, the weather correlation between winter solstice and Spring Festival is not absolute. For example, in some years, it is also possible that the temperature is higher and there is more precipitation during the winter solstice, or the temperature drops suddenly during the Spring Festival and a cold wave strikes.

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". On the day of "March 9 and April 9", the accumulated heat is the least, the temperature is the lowest, and the weather is getting colder and colder. China has a vast territory, and the climate and landforms vary greatly from place to place.

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.

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.
