Precipitation Characteristics - The cold wave will bring complex precipitation patterns, including rain transitioning to sleet, freezing rain, and snow, particularly in areas south of the Qinling-Huaihe line [2]. - The risk of freezing rain is highlighted as being significantly higher than that of heavy snow, with potential for severe disruptions to transportation and power infrastructure [2]. Agricultural Concerns - The Ministry of Agriculture and Rural Affairs, along with the China Meteorological Administration, has issued warnings regarding frost damage risks to winter wheat and rapeseed crops, advising farmers to take preventive measures [2][3].

本报讯（四川日报全媒体记者 陈婷）三九天像入春，四九天今冬最冷，四川冷暖大反转。2026年 第一场寒潮天气即将来袭——中央气象台1月15日发布重要天气提示，预计1月17日至21日，寒潮 过程将影响我国，带来大风降温天气，南方地区气温下降显著；中东部地区将出现入冬以来最强 雨雪冰冻天气过程，部分地区有冻雨。 1月17日，是今年四九天第一天。1月20日，我国将迎来大寒节气。气象资料记载，"小寒"是气温 最低的节气，只有少数年份的"大寒"气温低于"小寒"。四川省气候中心的资料也印证了"小寒胜大 寒"之说：常年三九天全省平均气温为4.7摄氏度，盆地平均气温为6.1摄氏度；常年四九天全省平 均气温为5摄氏度，盆地平均气温为6.4摄氏度。但今年可能不一样。从1月8日进入三九天以来， 四川多地暖出新纪录。随着1月17日进入四九天后，强冷空气来袭，有气象专家表示，四九天可能 成为四川今冬数九寒天中最冷的九天。 天气过程，盆地大部和凉山州东北部日平均气温累计下降6摄氏度至9摄氏度，局部可达10摄氏度 及以上，冷空气影响盆地时伴有大风天气，高海拔山区有雨夹雪或雪。 寒潮对四川盆地的影响，预计最早在1月18日夜间显现。四川省气象台 ...

Group 1 - The core weather event affecting Shandong province includes a strong cold air mass leading to a significant drop in temperatures, with forecasts indicating a temperature decrease of 10℃ to 12℃, and in some areas exceeding 14℃ [1][2] - A series of weather warnings have been issued, including a blue snow warning, orange road icing warning, yellow cold wave warning, and yellow low-temperature warning, indicating severe weather conditions expected from January 17 to January 19 [1][2] - The expected minimum temperatures for various regions include -16℃ to -14℃ in the northwest and central mountainous areas, with coastal regions experiencing lows of -8℃ to -6℃, and other areas ranging from -10℃ to -8℃ [1] Group 2 - The precipitation forecast indicates an average accumulation of 8mm to 15mm, with snow depth reaching 3cm to 8cm, and potentially exceeding 12cm in some areas, which may significantly impact transportation due to road icing [2] - The weather conditions are expected to improve soil moisture and reduce forest fire risks, but the prolonged low temperatures and snow accumulation could adversely affect transportation, urban operations, and agricultural facilities [2] - The north winds are anticipated to negatively impact maritime transportation and coastal aquaculture, necessitating enhanced preventive measures [2]

Core Viewpoint - Chengdu is experiencing an unusually warm winter during the "Three Nine" period, with temperatures significantly higher than historical averages, attributed to specific weather patterns and the influence of high-pressure systems [1][2]. Group 1: Current Weather Conditions - As of January 16, Chengdu's average temperature during the "Three Nine" period is 6.6℃, which is 0.9℃ higher than the historical average, with a daily maximum temperature average of 14.7℃, exceeding the historical average by 5.6℃, marking the second highest in nearly 50 years [1]. - The city has recorded a total of 49.9 hours of sunshine during this period, which is approximately three times more than the historical average [1]. Group 2: Upcoming Weather Changes - A significant cold wave is expected to impact Chengdu starting on the evening of January 18, with temperatures projected to drop by 6-8℃ from current levels, bringing maximum temperatures down to around 7℃ by January 21 [3]. - The cold front will also bring 3-5 level north winds and light rain, with potential for mixed rain and snow in western mountainous areas, along with risks of road icing [3]. Group 3: Meteorological Insights - The warm weather in Chengdu is primarily due to the influence of a high-pressure system that has led to sustained clear weather and increased solar radiation, while cold air paths have shifted north and east, minimizing their impact on Sichuan [2]. - The upcoming cold wave is expected to be characterized by rapid temperature drops, significant temperature declines, and a wide area of impact, prompting advisories for residents to prepare for colder conditions [3].

Group 1 - The core viewpoint of the article is that a significant cold wave is set to impact China from January 17 to 21, bringing the strongest rain, snow, and freezing weather of the winter season to the central and eastern regions [1][2][3] Group 2 - The cold wave is expected to cause temperature drops of 6 to 10 degrees Celsius across most of the country, with some areas experiencing drops exceeding 12 degrees Celsius [2][4] - The main impact period of the cold wave is from January 17 to 21, with a gradual southward penetration pattern [3][4] - This cold wave differs from the 2016 "King of Cold" wave and the 2008 snow disaster, as it features a gradual rather than rapid southward movement and is characterized as a "process" rather than "persistent" cold weather event [3][4]
