Core Viewpoint - The article discusses the phenomenon of "cold flow snow" in the coastal cities of Yantai and Weihai in Shandong Province, highlighting its unique characteristics and formation process, as well as its prevalence in these areas during winter. Group 1: Cold Flow Snow Characteristics - Yantai and Weihai are referred to as "China's snow pit" due to their significantly higher snowfall compared to other regions in Shandong, with cold flow snow accounting for over 80% of total snowfall days [4][6]. - The average annual number of cold flow snow days in Yantai is approximately 39 days [4]. Group 2: Formation of Cold Flow Snow - Cold flow snow occurs when warm, moist air from the sea rises and cools, leading to snow formation as cold air moves southward [4][6]. - The geographical location of Weihai, surrounded by the Yellow Sea, contributes to the frequent occurrence of cold flow snow, with significant snowfall recorded, such as 80.3 mm in Yantai's Zhifu District from late 2005 to early 2006 [6]. Group 3: Weather Impact and Forecast - The Central Meteorological Administration forecasts that cold air will lead to temperature drops of 4°C to 6°C in northeastern regions, with significant snowfall expected in areas like Inner Mongolia and northeastern provinces [7][9]. - A blue wind warning has been issued, predicting strong winds of 5 to 7 levels in various regions, including the Shandong Peninsula [9].
