“中国雪窝”为何在胶东半岛？

Group 1 - The core viewpoint of the articles highlights the unique snowfall characteristics of Weihai and Yantai, which are referred to as "China's snow nest" due to their significant snowfall compared to other regions in Shandong and even Northeast China [1][2]. Group 2 - From January 10 to 11, Weihai experienced heavy snowfall, with a recorded snowfall of 12 millimeters in just three hours, and a maximum snow depth of 21 centimeters at the national weather station [1]. - The geographical location of the Jiaodong Peninsula, surrounded by the sea, contributes to the high snowfall, as cold air from the north picks up moisture from the relatively warm waters of the Bohai and Yellow Seas, leading to efficient snow formation [1][2]. - Cold stream snow is predominant in Weihai and Yantai, accounting for over 80% of total snowfall days, with an average of about 39 days of cold stream snow per year at Yantai Laishan Airport [2].
