Introduction to the 24 solar terms of heavy snow

Heavy snow is one of the 24 solar terms in China. In this solar term, the cold weather gradually strengthened and it began to snow.

Heavy snow is the third solar term in winter, and it is also a sign of the gradual escalation of cold degree. At this time, the northern region has entered the cold winter, the weather is extremely cold, and there may be continuous snowfall in most areas.

The solar term of heavy snow is very important to agriculture. Especially in the farmland in the north, the crops have been harvested and the land has begun to recuperate. The arrival of heavy snow can cover the land and protect the farmland from the cold.

At this time, fresh shrimp, fresh fish and other seafood are delicious and are people's favorite ingredients.

Climatic characteristics of heavy snow solar terms

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 largest snowfall 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 in spring, the "rain" solar term. 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 strong and strong, and the warm air flow continues to rise strongly on the back of the dense cold air flow, which may lead to heavy snow.
