国家气象中心：2月预计有4次冷空气过程影响我国

Core Viewpoint - The National Meteorological Center predicts four cold air processes affecting China in February, with varying intensity and timing [1][2]. Temperature Summary - Most regions in China will experience temperatures close to or above normal, with southern areas generally 1-2°C higher than usual. However, northern regions such as northern Hebei, central and eastern Inner Mongolia, western Northeast China, northwestern Tibet, and northern Xinjiang will see temperatures 0.5-1°C lower than normal [2]. Precipitation Summary - Precipitation will be uneven, with northern regions experiencing more rainfall compared to southern areas. Specifically, northeastern regions and eastern Inner Mongolia will see precipitation 20-50% above normal, while southeastern China and parts of southwestern China will experience 20-50% less rainfall, with western Yunnan seeing a decrease of 50-80% [2]. Key Areas of Concern - Cold Weather Impacts: Northern regions should prepare for strong cold snaps and heavy snowfall, particularly in eastern Inner Mongolia, northeastern areas, northern Hebei, and northern Xinjiang. Recommendations include monitoring weather changes and preparing for agricultural and livestock protection [3]. - Low-Temperature Rain and Snow: Areas such as northeastern and central China should be vigilant for low-temperature rain and snow, which could disrupt transportation and energy supply [3]. - Meteorological Drought Risks: Southern and southwestern regions may face meteorological drought due to high temperatures and low precipitation. Authorities are advised to manage water resources effectively and enhance fire prevention measures [3]. - Dust and Low Visibility: The northwestern regions and southern Xinjiang are expected to experience increased dust days, while the Fenwei Plain and Yangtze River Delta may see more fog or haze, impacting health and transportation [4].
