What is a snowstorm?

Snow disaster, also known as white disaster, is a natural phenomenon caused by long-term heavy snowfall. It is a frequent meteorological disaster of animal husbandry in pastoral areas of China, mainly referring to animal husbandry areas that rely on natural grassland for grazing. Due to the heavy snowfall, thick snow cover and long duration in winter, the normal grazing activities of animal husbandry are affected. The occurrence of snowstorm

The harm to animal husbandry is mainly that the snow covers the grassland and exceeds a certain depth. Some snow is not deep, but the density is high, or the snow is covered with ice to form an ice shell, which makes it difficult for livestock to open the snow layer to eat grass and cause hunger. Sometimes the ice shell is easy to cut the ankles of sheep and horses, causing frostbite, which often leads to emaciation of livestock, abortion of young livestock, low survival rate of old and weak young livestock and increased death. At the same time, it also seriously affects or even destroys lifeline projects such as transportation, communication and power transmission lines, posing a threat to the life safety of herders. Snow disasters mainly occur in stable snow-covered areas and unstable snow-covered mountainous areas, and occasionally appear in instantaneous snow-covered areas. Snow disasters in pastoral areas in China mainly occur in Inner Mongolia grassland, northwest China and parts of Qinghai-Tibet Plateau.

According to the formation conditions, distribution and manifestations of snow disasters in China, snow disasters can be divided into three types: avalanche, wind-blown snow disasters and snow disasters in pastoral areas.
