Core Viewpoint - A significant change in weather patterns is expected in China as three cold air masses will impact the country, leading to a transition from warm temperatures to colder conditions, accompanied by widespread rain and snow starting December 30, 2025 [1][4]. Group 1: Cold Air Masses - The first cold air mass will affect northern regions from December 28 to 30, with temperatures dropping by 4-6°C, and in some areas of Inner Mongolia and Northeast China, temperatures may fall by over 10°C [1][3]. - The second cold air mass, stronger and longer-lasting, will impact from December 30 to January 2, causing a temperature drop of 6-8°C in various southern regions, with local drops exceeding 10°C [1][3]. - A third cold air mass is expected around January 5, leading to a further temperature decrease of 4-6°C in most of central and eastern China, with local areas experiencing drops of over 8°C [3]. Group 2: Rain and Snow Forecast - A major shift from dry weather to widespread rain and snow is anticipated starting December 30, driven by the interaction of warm moist air and cold air masses [4][6]. - From the night of December 30 to January 1, regions including eastern Tibet, parts of Northwest China, and central and eastern North China will experience light to moderate snow or sleet, with some areas facing heavy snow or blizzards [6][8]. - The most intense snowfall is expected from the night of December 30 to December 31, with significant impacts on travel due to slippery roads and reduced visibility, particularly in regions like southern Shaanxi and western Henan [6][8].
