Why does Yantai snow so much, and it is called "Snow Nest"?

Reason: In China, Yantai and Weihai, located in Jiaodong Peninsula, are called "snow nests" because their snowfall in winter is much higher than that in other regions with similar geographical locations. Yantai and Weihai are located in the northeast of Shandong Peninsula. Compared with inland and coastal areas of Wei Yan, they are veritable "snow nests". The topic is closely related to the geographical location and topographical features of these two cities. There are two reasons for the frequent heavy snow in winter in Wei Yan: 1. The strong cold air from Siberia goes south, and the ground is affected by the topographic shear of Liaodong Peninsula and Shandong Peninsula, and the cold air keeps dumping, resulting in a large amount of snowfall for a long time. 2. When the cold air goes south from Northwest Road, it will pass through Bohai Sea. In winter half a year, the west branch of the warm current to Malaysia transports warm water from the open sea to the Yellow Sea and Bohai Sea, and the surface water temperature shows a high temperature tongue extending from the South Yellow Sea to the Bohai Sea. The central part of Bohai Sea is located at the top of warm tongue. Because the surface temperature of Bohai Sea is higher than that of air, the warm sea surface transports a lot of heat and water vapor to the dry and cold air layer, and the large sea temperature difference makes its temperature stratification unstable, thus forming snowfall. From the mechanism of snowfall and the intensity of cold air, the temperature on the surface of warm water also has an influence on the cold flow snowfall. The snowfall mechanism of cold current snowfall is similar to the Great Lakes effect blizzard in the United States. According to the relevant research results in the United States, the lake temperature difference is the most important condition for lake effect snowfall. For Wei Yan, Bohai Bay is equivalent to the "Great Lakes" of the United States, that is, "inland lakes". The mountainous areas of Yantai and Weihai also provide the possibility for cold air to rise and then form snowfall. Extended data:

Preparation for driving in snowy days: 1, cover the front windshield with a piece of cloth at night; 2. Inflate some air into the tire to increase the contact area between the car and the icy road surface and enhance the adhesion of the tire. 3. Check whether the glass water and wiper are normal, and make sure that the front line of sight is clear. The glass of doors and windows may be frozen, so it is best not to open it before blowing. 5. Prevent the window from fogging. Also pay attention to the rearview mirror outside the car. It is best to prepare a piece of cotton cloth so that you can clean the rearview mirror at any time when parking. But remember: don't wipe while walking. Pay attention to road travel preparation in snowy days: 1, travel in snowy days, slow down and drive slowly, and the speed should not exceed 40 km/h, and choose the appropriate driving mode according to the road conditions. 2. In case of sideslip, don't turn in a hurry or brake suddenly, which will only make the sideslip worse.
