Core Viewpoint - A significant cold wave is expected to impact central and eastern China from February 5 to 7, with temperature drops exceeding 12°C in many areas, and localized drops potentially exceeding 20°C [1][3]. Group 1: Temperature Changes - The cold air will lead to a reversal of the warm weather pattern, with temperatures in central and eastern regions dropping by 6 to 10°C from north to south [1][5]. - The northeastern region, Jianghuai, and eastern Jiangnan will be the core areas for temperature drops, with some areas experiencing decreases of 12 to 16°C, and localized drops over 20°C [3][5]. - On February 5, the main temperature drops will be concentrated in Northeast and North China, with areas like Inner Mongolia, northern Hebei, Beijing, and western Liaoning experiencing drops of 12 to 16°C, and localized drops around 18°C [3][5]. Group 2: Weather Conditions - The cold wave will be accompanied by increased cloud cover and reduced sunlight, leading to more significant temperature drops during the afternoon compared to nighttime [3]. - Southern regions will remain warm initially, with maximum temperatures generally exceeding 15°C, particularly in southern Jiangnan and South China, where temperatures may exceed 20°C [5]. - By February 6, the cold front will rapidly move southward, affecting areas south of the Yangtze River, with maximum temperatures dropping below 10°C in the middle and lower reaches of the Yangtze River, accompanied by rain and snow [5][7]. Group 3: Public Advisory - The public is advised to dress appropriately for the significant temperature fluctuations and to be cautious of travel conditions due to the cold wave and accompanying precipitation, especially during the Spring Festival travel period [9].
