Core Viewpoint - A significant cold wave is impacting China, leading to rapid temperature fluctuations and widespread precipitation, particularly affecting the central and eastern regions as the Spring Festival approaches [1][5]. Group 1: Temperature Changes - The cold wave has already begun to affect regions such as Gansu, Ningxia, and Inner Mongolia, with temperature drops exceeding 10°C in many areas [3]. - Major temperature declines are expected tomorrow, with some areas in Henan, Shandong, and Jiangsu experiencing single-day drops of over 10°C, and localized drops reaching 20°C [4]. - On the eve of the Spring Festival (February 16), the core area of temperature decline will shift southward, with regions like Guizhou, Hunan, Jiangxi, Zhejiang, and Anhui seeing drops between 12°C and 22°C [4]. Group 2: Precipitation and Weather Conditions - A large-scale rain and snow event is anticipated, with the most intense precipitation occurring tomorrow, particularly in regions such as southeastern Tibet, central western Sichuan Plateau, northern Hubei, and western Henan, where heavy snow is expected [12]. - On February 16, the intensity of rain and snow will decrease, but areas like eastern Tibet and parts of Inner Mongolia will still experience light to moderate snow or sleet [13]. - By February 17 (the first day of the Lunar New Year), regions including Guizhou, Guangxi, Hunan, Jiangxi, and Fujian will continue to see overcast and rainy weather [14]. Group 3: Temperature Recovery - Following the cold wave, temperatures are expected to rise quickly starting February 17, with most areas experiencing a warming trend until February 21, when no significant cold air activity is forecasted [10]. - By February 20 (the fourth day of the Lunar New Year), many southern regions will see maximum temperatures return to above 20°C, with the 10°C isotherm moving north into southern Northeast China [11].

Core Viewpoint - The article discusses the upcoming cold air activities in China over the next ten days, which will lead to significant temperature drops and precipitation events, including snow. Group 1: Cold Air Activities - Three rounds of cold air are expected: from December 28 to 30, December 30 to January 2, and around January 5 [2][4] - The first cold air will primarily affect northern regions, with temperature drops of 4-6°C and some areas experiencing drops over 10°C [2][4] - The second cold air is stronger and will impact a broader area, with temperature decreases of 6-8°C in various southern regions [2][4] Group 2: Temperature Changes - The northeastern region will experience the most significant temperature fluctuations, with cumulative drops of 10-20°C expected by January 1 [4] - The third cold air will also lead to temperature drops of 4-6°C in the central and eastern parts of the country, with some areas exceeding 8°C [4] Group 3: Precipitation Events - Starting December 30, the cold air will trigger a new round of widespread rain and snow [5][6] - From December 30 night to January 1, regions such as Tibet, the northwest, and parts of central China will see snowfall, with accumulations of 2-8 mm, and some areas reaching 10-15 mm [6] - High-altitude areas may experience even higher snowfall, with localized amounts reaching 20 mm [6] Group 4: Public Advisory - Meteorological experts advise the public to adjust clothing and take precautions against the cold, especially in regions facing heavy snow and low temperatures [8]

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].

Core Viewpoint - A significant warming trend is occurring across most of China, expected to last until December 29, 2025, followed by a strong cold air mass that will lead to temperature fluctuations [1][3][5]. Group 1: Temperature Trends - The warming trend will see northern regions reaching high temperatures, with the 0°C line moving unusually north into central Jilin, and southern regions experiencing temperatures above 20°C [1]. - After the warming period, two cold air events are forecasted, with temperatures in northern areas dropping by 4-6°C, and some regions in Inner Mongolia and Northeast China experiencing drops of over 10°C [3]. - A strong cold air mass is expected to impact central and eastern regions from December 30, 2025, to January 3, 2026, causing temperature drops of 6-8°C, with local areas experiencing drops exceeding 10°C [5]. Group 2: Regional Impacts - The Northeast region will experience the most significant temperature fluctuations, with current temperatures being 8-10°C above the average for late December, but expected to drop by 10-20°C by January 1 [7]. - Southern regions will also see notable temperature changes, with maximum temperatures near 20°C before the cold air arrives, dropping to single digits during the New Year holiday [8]. - The cold air mass will also bring widespread rain and snow from December 30 to January 3, affecting various regions including the Northwest, North China, and parts of the South [8].
