Solar terms of heavy snow in 2022: 65438+February 7, 2022 1 1:46:04, and the lunar calendar1/month1Thursday. "Snow" is the product of cold water vapor, representing cold and precipitation. Snow solar term is a climate concept, which represents the climate characteristics during the snow solar term, namely temperature and precipitation. Like the light snow solar term, the heavy snow solar term is a solar term reflecting the changing trend of temperature and precipitation, and it is also a reflection of ancient farming culture on festivals.

Meteorological changes of solar terms in heavy snow

"Heavy snow" is a solar term reflecting the climate characteristics. The characteristics of heavy snow solar terms are that the temperature drops obviously compared with autumn and early winter, and the precipitation increases. During the heavy snow season, most parts of China have entered the cold winter, and the minimum temperature in some parts of the north has dropped to 0℃ or below. Cold and warm air in areas where strong cold air fronts meet, precipitation (rain or snow) increases. Meteorology refers to the condensation of water vapor falling from the sky to the ground, such as rain, snow and hail, as "precipitation".

The heavy snow in solar terms and the heavy snow in weather have different meanings. In fact, the snow in heavy snow solar terms is often not as big as that in light snow solar terms, and the solar terms with the largest amount of snow in the whole year are not in light snow and heavy snow solar terms. Take the middle and lower reaches of the Yellow River as an example. Among the 24 solar terms, the solar term with the most snow all year round is neither "light snow and heavy snow" nor "slight cold and severe cold" (because the temperature was low at that time and there was less water vapor in the atmosphere), but "rain" in spring. This snow is not the biggest in the solar terms. The reason is similar to "light snow is bigger than heavy snow". That is, the end of February in the Gregorian calendar has passed the coldest period of the year. In early spring, the warm air in the south began to be active and the water vapor began to be rich. At this time, the cold air force in the north is still very strong, and the warm air flow rises strongly and persistently on the back of the dense cold air flow, which may lead to heavy snow. There is no necessary connection between solar terms and heavy snow.
