Shenyang first snow time 2021

November 7, 2021.

Snow, a commonly used word in Chinese, is pronounced xuě. It was first seen in the oracle bone inscriptions of the Shang Dynasty. It is solid water in the form of snowflakes that falls to the ground from mixed clouds. The basic meaning is that the white crystals falling in the sky, mostly hexagonal, are formed by the condensation of water vapor in the sky when it is cooled to below zero degrees Celsius. Snow will only appear under the influence of very cold temperatures and temperate cyclones, in subtropical areas. and tropical areas have a small chance of snow.

Water is the basis for the existence of all living things on the earth. The changes and movements of water have created our world today. On the earth, water is constantly circulating. Water in the ocean and on the ground is heated and evaporates into the sky. This water vapor moves to other places with the wind. When it encounters cold air, it forms precipitation and returns to the surface of the earth. .

This kind of precipitation is divided into two types: one is liquid precipitation, which is rain; the other is solid precipitation, which is snow or hail. Most snow falls from nimbostratus clouds and altostratus clouds, and the precipitation intensity changes slowly; snowfall from cumulonimbus clouds in cold weather has the characteristics of showers, which are called snow showers.
