What does a snow shower mean?

A snow shower is a short snowfall with a sudden start and end time.

Rain and snow mostly come from cumulonimbus, cumulonimbus and cumulonimbus stratocumulus. Snow showers are characterized by sudden stop, that is, they can't stop for a while, and their intensity changes greatly. In the process of snowfall or snow stopping, factors such as air pressure, temperature and wind force will also change significantly. From the color and appearance, there is no difference between snow and snow showers, but the intensity changes of the clouds they form are different when they fall, and the individuals with snow showers are often larger than those with snow.

Shower is a weather phenomenon caused by cold and warm convection in the atmosphere. There is a warm current in the south and a cold current in the north. In winter, the sky above the north is covered with high pressure, and the wind blows from north to south. The warm current in the south is relatively weak, and snowfall occurs after the meeting. The strong cold current in the north makes the cold and warm Liu Xiang and clouds drift to the south, while the temperature in the south is higher than that in the north, which makes the snow in the clouds melt into rain and form snow showers in the north.

Matters needing attention in snowy weather

1, anti-skid: rainy and snowy weather leads to slippery roads, so it is necessary to pay attention to travel safety and prevent accidental falls.

2. Fall prevention: It is recommended that people who ride electric cars and bicycles should try to walk or take public transportation.

3. Anti-smashing: In addition, due to heavy snowfall in some areas, trees are in danger of being crushed. Pedestrians should try their best to stay away from high-rise buildings such as trees to avoid being crushed by collapse.

4. Anti-collision: Friends who drive on slippery roads must drive carefully. On the one hand, they must keep their distance and step on the brakes in time. On the other hand, they must pay special attention to pedestrians on the road to prepare for dodge.

5. Bump prevention: In snowy weather, pay attention to stay away from billboards, temporary buildings, carports, trees, telephone poles and high-voltage towers. Once crushed by snow, the consequences will be very serious, so be careful when passing through bridge opening and eaves, or drive around.
