Many countries in Europe are welcoming snowfall. What are the adverse effects of snowfall?

The snow level specification is general, which refers to the specification that it snows or snows continuously within the required time range, and the amount is converted into precipitation. This specification generally selects two specifications with delay time of 12 hours and 24 hours.

if the 24-hour rainfall is taken as the zoning standard, among them, the rainfall of .1 mm ~ ～2.4mm is slight cold, 1.3 mm ~ 3.7 mm is small to medium snow, 2.5 mm ~ 4.9 mm is medium to heavy snow, and 3.8 mm ~ 7.4 mm is medium to heavy snow, so that 5. mm ~ 9.9 mm is snow and 7.5 mm ~ 14.9 mm is heavy snow. If the 12-hour rainfall is taken as the zoning standard, among them, the rainfall of .1 mm ~ ～.9mm is slight cold, .5 mm ~ 1.9 mm is small to medium snow, 1. mm ~ 2.9 mm is medium to heavy snow, and 2. mm ~ 4.4 mm is moderate to heavy snow, so that 3. mm ~ 5.9 mm is snow, and 4.5 mm ~ 7.4 mm is heavy to blizzard games, and the rainfall achieves or exceeds it.

There are many harmful effects of this snow. For example, the rainy and snowy days will cause low average temperature, muddy roads and low visibility in some areas, which will cause some harm to urban traffic. Therefore, people should pay special attention to slow down when driving, and try not to choose cycling as much as possible. Friends who fly should pay attention to the delay of the plane. In rainy and snowy days, with the decrease of temperature and the experience of severe cold, it is very easy to cause respiratory diseases and bronchitis. Therefore, people should wear clothes when going out, and their ears, hands, feet and neck should not be exposed as much as possible, so as to do a good job in anti-freezing and warm-keeping measures. At the level of agriculture and animal husbandry, areas with serious snowfall will do harm to protected vegetables and aquaculture, and will also do harm to shipment and freight logistics of protected vegetables. It is suggested that the production and manufacture of protected vegetables and aquaculture should pay attention to the immediate maintenance of structural reinforcement equipment, do a good job in thermal insulation and antifreeze of arch sheds, and also do a good job in feed storage in agricultural and pastoral areas, and actively prevent the greenhouse from being damaged or the equipment crops from being damaged by strong snow in some areas. Attention should be paid to bypassing the whole process of rain, snow and weather in the western region, the eastern region, the south of North China, Huanghuai and other places.

naturally, there is no doubt that this rainy and snowy weather will also produce some beneficial hazards. For example, the area covered by rainy and snowy weather is a winter wheat planting area. Snowing can greatly improve soil moisture, and then reasonably curb diseases. It can be said that the snow is auspicious for a bumper year. In addition, rainy and snowy days will also have a prominent effect on air filtration in many areas, and also have a positive and active harm to reducing forest fires.
