Is the snowy solar term sunny or cloudy?

Sunny days and cloudy days of heavy snow solar terms have certain effects on crop growth and climatic conditions. Generally speaking, it is better to have a sunny day than a cloudy day because it can provide enough sunshine, which is beneficial to photosynthesis and plant growth. In contrast, cloudy days may be bad for the growth of plants. On cloudy days, the sun is blocked by clouds, so plants can't fully absorb and utilize the ultraviolet rays and heat in the sun.

Sunny days help to raise the temperature and promote the development and growth of plants. On sunny days, plants can absorb carbon dioxide and release oxygen through photosynthesis, thus improving air quality. In addition, sunny days can promote the survival and reproduction of insects and small animals, increase the content of organic matter in soil, and contribute to soil fertility and sustainability.

Brief introduction of heavy snow solar terms

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).
