I should know the weather next time.

"Most afraid of heavy snow and sunny days" means that if there is sunny days after heavy snow, the temperature will drop sharply, leading to frost. This frost is very bad for the growth of crops and plants.

From the meteorological point of view, sunny days mean dry weather and abundant sunshine, which is beneficial to plant photosynthesis and crop growth. In the heavy snow solar term, such weather is conducive to the warmth and cold resistance of crops and lays the foundation for the bumper harvest in the coming year. In addition, sunny weather also makes people feel more happy, which is conducive to carrying out various winter activities, such as skiing and skating.

Old people in rural areas say that "it will be sunny if they are afraid of heavy snow", because the solar term of heavy snow is sunny, which not only indicates that winter may be warm, but also indicates that there may be cold weather at the end of next spring. Farmers depend on the weather for food, and climate change has a great impact on agriculture. In ancient times, once there was a poor harvest year, it was easy to cause famine, so people were afraid of heavy snow and sunny days.

Agricultural proverbs are the summary of our ancestors' experience and can guide our agricultural production to some extent. The significance of the above agricultural proverbs is to warn us to pay attention to the change of weather in order to arrange agricultural production reasonably.

Heavy snow weather characteristics:

Heavy snow is 2 1 of the 24 solar terms and the third solar term in winter. When the sun reaches the longitude of 255 degrees, the node time is 65438+February 6-8 in Gregorian calendar every year. The solar term of heavy snow is the beginning of the second month of the dry calendar, marking the official start of the mid-winter season.

Heavy snow is a solar term reflecting climate characteristics. Heavy snow solar terms are characterized by a significant drop in temperature and an increase in precipitation. During the heavy snow, the national temperature dropped significantly, and the cold air in the north became more and more active.

The heavy snow solar term is a climate concept, which represents the climate characteristics during the heavy snow solar term, that is, temperature and precipitation (water vapor condensate such as rain, snow and hail falling from the sky to the ground is called "precipitation" in meteorology). 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.
