What is Leng Xue?

Cold current snow refers to the unique weather situation in the Bohai Rim region, mainly because high-altitude strong cold air passes south through the ocean surface and meets the warm and humid air on the ocean surface, and snowfall occurs after the two sides meet.

This cold current snowfall is very common in the northern part of Shandong Peninsula, including Yantai and Weihai, as well as Pingdu and Laixi in Qingdao.

Characteristics of cold current snowfall;

The duration is short, usually no more than three hours, and it often snows when the sun is shining. Sometimes it lasts a long time. For example, in 2005, the heavy snow in Weihai and Yantai lasted for half a month, which had a great impact on the local people.

Causes of common cold current snowfall in Shandong peninsula;

This is caused by its unique geographical location, topographical features and cold air types.

Geographically, the northern part of Shandong Peninsula is surrounded by the sea on three sides. Because the seawater temperature is higher than the inland land surface in winter, the air above the sea surface is relatively warm and humid and rich in water vapor. When the cold air from the north goes south to the sea surface, the warm and humid air above the sea surface rises upward, and when it reaches a certain height, it will condense into snowflakes and fall down to form snowfall.

This snowfall is called "cold current snowfall". The formation of this snowfall requires special conditions. Because there is no warm and humid air on the peninsula surface, even if it encounters cold air from the north, it will not form snowfall.

In addition, the special topography of Shandong Peninsula also plays a certain role in the formation of cold current snowfall. Due to the release of unstable energy, the uplift of coastal hills and mountains in the northern peninsula is the trigger condition for the formation of low clouds. Yantai and Weihai are just to the north of the mountain. When the northwest wind blows, the warm and humid air near the sea surface will climb along the hills, which will also increase the snowfall. Therefore, this cold current snowfall is also common in Yantai and the northern coast of Weihai.
