连日来，多地遭遇入冬以来最强寒潮侵袭，"断崖式"降温开启"速冻"模式，给生产生活带来显著影响。 寒潮因何而起，将对农业设施与作物生长带来哪些挑战？气温骤降后，冰雪运动"热"了起来，人们如何安全地享受"雪趣"？记者就此采访了相关专 家。 强冷空气接踵而至 11月底以来，我国北方多地出现降温天气。随着寒潮东移南下，并有冷空气补充影响，我国大部降温明显。中央气象台首席预报员杨舒楠分析，当 前寒潮最显著的特点是降温幅度大，波动较为频繁。 辽宁省气象台首席预报员张宸赫介绍，11月底至12月5日，辽宁省多地累计降温幅度10到20摄氏度。记者5日在沈阳市浑南区浑南中路看到，天空飘 着小雪，寒风呼啸，市民换上厚衣，全副"捂"装出行。 除东北地区外，山东、河北、北京等多地出现剧烈降温，最低气温0摄氏度线已南压至华北南部至陕西中部、甘肃南部一带。长春、沈阳、石家庄等 城市纷纷创下半年来气温新低。 "北极涡旋"是本次北方气温骤降的幕后推手之一。受访专家解释，随着"北极涡旋"南侧的高空槽发展加强，形成了"极冷"的冷涡系统，进一步增强 了寒潮威力，让公众感到"速冻"般的寒冷。 6日以来，本轮寒潮已接近尾声，北方大部地区的气温开始反弹。 ...

强冷空气接踵而至 11月底以来，我国北方多地出现降温天气。随着寒潮东移南下，并有冷空气补充影响，我国大部降温明显。中央气象台首席预报员杨舒楠分 析，当前寒潮最显著的特点是降温幅度大，波动较为频繁。 连日来，多地遭遇入冬以来最强寒潮侵袭，"断崖式"降温开启"速冻"模式，给生产生活带来显著影响。 寒潮因何而起，将对农业设施与作物生长带来哪些挑战？气温骤降后，冰雪运动"热"了起来，人们如何安全地享受"雪趣"？记者就此采访了 相关专家。 辽宁省气象台首席预报员张宸赫介绍，11月底至12月5日，辽宁省多地累计降温幅度10到20摄氏度。记者5日在沈阳市浑南区浑南中路看到， 天空飘着小雪，寒风呼啸，市民换上厚衣，全副"捂"装出行。 在大连市瓦房店市西杨乡，农技人员深入田间地头，针对冬小麦苗情进行技术指导。"我们在种植阶段就给冬小麦盖了一层膜。为了应对本轮 寒潮，我们提前灌水和施肥，提高冬小麦的抗寒性。"种粮大户刘作洲说，他今年种植了600亩冬小麦，现在苗势较好，农膜下绿色若隐若现。 寒潮之下，保障冬季"菜篮子"供应同样至关重要。 黑龙江省农业科学院耕作栽培研究所所长李柱刚介绍，本次寒潮虽然持续时间短，但强度较大。蔬菜大棚内 ...

Core Viewpoint - The article discusses the impact of a cold wave affecting various regions in China, with temperatures dropping significantly, particularly in the northeast and northern areas, while also forecasting a subsequent temperature rebound. Summary by Sections - **Cold Wave Impact**: The article highlights that as of December 2, extreme cold weather has been recorded in northeastern regions, with temperatures dropping below -30℃ in parts of Inner Mongolia and Heilongjiang [1]. - **Temperature Forecast**: It is expected that on December 3, many northern areas will experience further drops, with temperatures reaching as low as -20℃ in several locations [1]. In contrast, southern regions will see a shift from previously high temperatures to much lower ones, with maximum temperatures around 10℃ [1]. - **Temperature Recovery**: Following the cold wave, temperatures are predicted to rebound significantly by the weekend, with increases of 6 to 10℃ in many areas, and up to 15℃ in northeastern regions, bringing temperatures above 0℃ [5]. - **Wind Alerts**: The Central Meteorological Observatory issued blue wind alerts, predicting winds of 5-6 levels in several northern regions and stronger winds of 7-8 levels in various sea areas, including the Taiwan Strait [7][8]. - **Cold Wave Warning**: A blue cold wave warning was issued, indicating a temperature drop of 6-8℃ in regions such as Huanghuai, Jianghuai, and parts of Jiangnan, with some areas experiencing drops exceeding 10℃ [10].

Summary of Key Points from the Conference Call Industry Overview - The conference call discusses the climate outlook for the winter of 2025 in China, focusing on temperature and precipitation patterns influenced by various climatic phenomena such as La Niña and the Indian Ocean Dipole. Core Insights and Arguments 1. **Temperature Trends**: The overall winter of 2025 is expected to be relatively warm, with average temperatures close to or slightly above the long-term average. However, certain regions, particularly in the northeast and southeast, may experience cooler conditions [5][19][22]. 2. **Precipitation Patterns**: There is a significant disparity in precipitation across regions, with northern areas like Shandong and Henan experiencing more than double the usual rainfall, while southern regions, particularly in Jiangnan and northern South China, are expected to see reduced rainfall [4][14]. 3. **La Niña Impact**: The likelihood of a La Niña event forming this winter is uncertain, but if it occurs, it could lead to increased cold air outbreaks and affect agricultural production and energy demand [5][7][20]. 4. **Cold Air Frequency**: The frequency of cold air outbreaks is expected to be higher in December and February, with January being relatively stable and warmer. The average winter temperature is projected to be close to the long-term average, but extreme cold events may still occur [15][22]. 5. **Regional Variability**: The western regions are predicted to be warmer, while the eastern and northeastern areas may experience slightly lower temperatures. The overall trend indicates that the northern regions will have more precipitation compared to the south [3][13][14]. 6. **Climate Change Effects**: The ongoing global warming trend is expected to lead to more frequent fluctuations between cold and warm periods, increasing uncertainty in weather patterns and energy consumption needs [20][21]. Other Important but Overlooked Content 1. **Agricultural Impact**: The persistent rainy weather has negatively affected crop production, particularly in regions like Shandong and Henan, where corn has been reported to rot due to excessive moisture [4]. 2. **Energy Supply Concerns**: While the energy supply pressure for the 2025-26 heating season is expected to be manageable, specific assessments of heating demand under varying weather conditions have not been conducted [21]. 3. **Historical Context**: The long-term trend shows an increase in average winter temperatures since 1961, with a warming rate of approximately 0.4 degrees Celsius per decade, indicating a shift towards warmer winters overall [5]. This summary encapsulates the key points discussed in the conference call regarding the climate outlook for winter 2025, highlighting the expected temperature and precipitation trends, the potential impact of La Niña, and the implications for agriculture and energy supply.
