This week, frequent cold air outbreaks are causing significant temperature fluctuations. Affected by successive waves of cold air, central and eastern China will experience noticeable cooling, with temperature drops of 8°C to 12°C in some areas—and locally exceeding 15°C. Accompanying the southward movement of cold air, strong winds and wintry precipitation—including rain, sleet, and snow—are expected. Northern regions may see light to moderate snow or sleet, while southern areas will be dominated by overcast skies and rain, resulting in a damp and chilly feel.Meteorologists warn that such sharp temperature swings can increase the risk of respiratory infections and cardiovascular issues. The public is advised to monitor weather forecasts closely, dress appropriately for changing conditions, and take precautions against the cold. Additionally, slippery roads and reduced visibility due to precipitation may pose travel hazards—extra caution is recommended. Elderly individuals, children, and those with chronic health conditions should limit outdoor activities and ensure proper indoor ventilation and warmth.The frequent cold surges are primarily driven by a strengthening Siberian High and eastward-moving upper-level troughs. In the coming days, ongoing clashes between cold and warm air masses will maintain atmospheric instability, preventing sustained warming. Temperatures are expected to gradually rebound by the weekend as the cold air weakens, though large diurnal temperature ranges will persist, warranting continued attention to updated weather information.
本周冷空气频繁来袭，气温起伏明显。受多股冷空气接连影响，我国中东部地区将经历明显的降温过程，部分地区降温幅度可达8℃至12℃，局地甚至超过15℃。伴随冷空气南下，大风、雨雪天气也将相继登场，北方多地可能出现雨夹雪或小到中雪，南方则以阴雨为主，体感湿冷。气象专家提醒，气温剧烈波动易诱发感冒、心脑血管等疾病，公众需及时关注天气预报，适时增减衣物，注意防寒保暖。此外，雨雪天气可能导致道路湿滑、能见度降低，出行需格外注意交通安全。建议老人、儿童及慢性病患者尽量减少外出，做好室内通风与保暖措施。此次冷空气活动频繁，主要与西伯利亚高压增强及高空槽东移有关。未来几天，冷暖空气将持续交汇，导致天气系统不稳定，气温难以稳定回升。预计本周末前后，随着冷空气势力减弱，气温将逐步回升，但昼夜温差仍较大，需持续关注最新天气动态。
