Why is the blizzard concentrated in Shandong Peninsula?

June 65438+February 65438+June 65438-June 65438+September 2023, the snowstorm was concentrated in Shandong Peninsula because of the Great Lakes effect.

Since June 65438+February 65438+June 2023, extreme snowfall has occurred in Yantai and Weihai, Shandong Province. This phenomenon is called the Great Lakes Effect in meteorology. The Great Lakes effect is a phenomenon in which cold air meets a large area of unfrozen water surface (lake and sea) to obtain water vapor and heat energy, and the precipitation (mainly snow) formed along the windward coast is obviously stronger than that in the surrounding areas which are also affected by cold air. The great lakes effect comes from the analysis of the obvious heavy snowfall in the five great lakes of North America.

In China, only a small part of the northern Shandong Peninsula will produce the Great Lakes effect snowfall, because the northern Shandong Peninsula is a large sea area. In June+February, 5438 and June+10/October, 5438, the sea surface temperature (relative cold air) was relatively high, and the cold air gained water vapor and heat energy from it. In addition, the hilly terrain of the peninsula lifted the cold air, thus strengthening the snowfall in the northern coastal areas.

Cold air passing through a large water body is the key to the formation of the Great Lakes effect. If this extreme snowfall is only caused by the cold wave, it is unreasonable that there is no such strong snowfall in the surrounding areas that are also affected by the cold wave.

Countermeasures for Blizzard Weather

1, please try to stay indoors and don't go out.

2. If you are outdoors, stay away from billboards, temporary structures and old trees to avoid injury. When passing under a bridge, eaves, etc. , pay attention to observe or bypass, so as not to hurt people because the ice melts and falls off.

3. Non-motor vehicles should deflate the tires a little to increase the friction between the tires and the road.

4, obey the traffic police command, obey the traffic arrangements.

5, pay attention to listen to the weather forecast and traffic information, to avoid the airport, expressway, ferry terminal and other suspended or closed and delayed travel.

6. When driving, drive slowly and keep a distance from the car in front. The vehicle should slow down in advance before turning to avoid sudden braking. If possible, install snow chains and wear colored glasses.

7. After the traffic accident, clear signs should be set at the rear of the scene to prevent serial crashes.

8. In case of power failure, report it to the electric power department quickly so as to deal with it quickly.
