Snow hazards and how to deal with them

Snow disaster introduction

Snow disaster, also known as white disaster, is a natural phenomenon caused by large snowfall over a long period of time. It is an animal husbandry meteorological disaster that often occurs in China's pastoral areas. It mainly refers to livestock husbandry areas that rely on natural pastures for grazing. Due to excessive snowfall in winter and heavy snow cover, the snow layer lasts for a long time and affects the normal grazing activities of livestock. A disaster. The damage to the animal husbandry is mainly caused by snow covering the grassland and exceeding a certain depth. Although some snow is not deep, but the density is high, or the snow is covered with ice to form an ice shell, it is difficult for livestock to open the snow layer to eat grass. Hunger, sometimes the ice shell is also easy to scratch the hoof of the sheep and horses, resulting in frostbite, resulting in thin livestock, often resulting in abortion of livestock, livestock survival rate is low, old and weak young animals are hungry and cold, deaths increased. At the same time, it also seriously affects or even destroys lifeline projects such as traffic, communications and transmission lines, and poses a threat to the lives and safety of herdsmen. Snow disasters mainly occur in stable snow-covered areas and unstable snow-capped mountains, occasionally in transient snow areas. The snowstorms in the Chinese pastoral areas mainly occurred in the grasslands of Inner Mongolia, parts of the northwest and the Tibetan Plateau.
According to the formation conditions, distribution scope, and manifestations of snow disasters in China, snow disasters are divided into three types: avalanches, wind-snow disasters (wind and snow flow), and snow disasters in pastoral areas.

Snow hazard

Mainly affect the lifeline engineering of transportation, communication, transmission lines, etc.; a large amount of snow can collapse the greenhouse and have a great impact on vegetable production. Heavy snow often accompanied by low temperatures, resulting in snow or ice formation on the road, people should pay attention to prevent slipping during the trip, vehicles should be added anti-skid chain, if necessary, close the ice road, so as not to cause casualties.

Snow disaster warning signal

Snow disaster warning signals are divided into three levels, which are respectively represented by yellow, orange and red.
Snowstorm Yellow Warning Signal Icon Meaning: Snowfall affecting traffic or animal husbandry may occur within 12 hours. Defense Guide: The relevant departments do a good job of preparing snow; the traffic department prepares roads for snowmelt; agricultural and pastoral areas should prepare good food and grass.

Snowstorm Orange Early Warning Signal Icon Meaning: There may be snowfall that has a significant impact on traffic or animal husbandry within 6 hours, or snowfall that has a significant impact on traffic or animal husbandry may continue to occur. Defense Guide: The relevant departments do a good job of road cleaning and melting of snow; drivers must drive carefully to ensure safety; rush wild animals to the circle for feeding; and other snowstorm yellow warning signals.

Snowstorm red warning signal icon Meaning: Snowfall that may have a great impact on traffic or animal husbandry within 2 hours, or snowfall that has a significant impact on traffic or animal husbandry may have continued. Defense Guideline: If necessary, close the road traffic; relevant emergency response departments are ready to start the emergency plan; do a good job in disaster relief work in the pastoral areas; other orange snowstorm warning signals.

Coping strategies

1. Everyone should stay indoors and not go out.
2. If you are outdoors, keep away from billboards, temporary structures and old trees to avoid bruising. When passing by under the bridge, eaves, etc., be careful to observe or bypass the passage so as not to cause injury due to melting of the ice cream.
3, non-motor vehicles should give the tire a small amount of deflation in order to increase the tire and road friction.
4. Obey the traffic police command and obey traffic arrangements.
5, pay attention to listening to weather forecasts and traffic information, to avoid delays due to airport, highway, ferry terminal, etc., or closed and delay travel.
6. When driving a car, drive slowly and keep a distance from the vehicle in front. Before the vehicle turns, it must be decelerated in advance to avoid sudden braking. Install snow chains and wear color lenses.
7. After a traffic accident occurs, clear signs should be set at the rear of the site to prevent accidents in the series.
8. In the event of a power outage, timely report to the power department for prompt processing.
