雪厚20厘米？！威海特大暴雪为何这么厉害

Core Viewpoint - The recent heavy snowfall in Weihai, Shandong, has attracted significant attention, with the phenomenon being characterized as "black snow" and leading to discussions about its unique meteorological conditions [1][3]. Group 1: Snowfall Characteristics - The snowfall depth reached over 20 centimeters, with some measurements indicating close to this figure [3]. - The snowfall is described as "cold flow snow," a rare type of snow in China, characterized by three main features: substantial snow volume, high accumulation efficiency, and excellent visual appeal [4][5]. Group 2: Formation of Cold Flow Snow - Cold flow snow forms when dry cold air flows over relatively warm sea surfaces, causing the warm moist air to condense into snowflakes [8]. - The geographical positioning of the Shandong Peninsula, surrounded by the sea, facilitates the formation of cold flow clouds, which contribute to the heavy snowfall in the region [8]. Group 3: Weather Forecast and Recommendations - The weather forecast for January 12 indicates a transition to partly cloudy conditions with temperatures ranging from 5°C to -2°C, and wind speeds of 5 to 6 levels [12]. - Residents and visitors are advised to prepare for potential snow conditions and consider visiting Weihai or nearby Yantai for winter scenery [12].
