未来一周华北南部、黄淮、江汉等地霾逐渐减弱消散

Core Viewpoint - The air quality in various regions of China is expected to improve over the next week due to the influence of cold air and precipitation, leading to a gradual reduction or dissipation of haze in affected areas. Group 1: Regional Forecasts - In the Beijing-Tianjin-Hebei and surrounding areas, air diffusion conditions are expected to improve, with haze gradually dissipating from January 29 [2]. - The Yangtze River Delta region will also experience good air diffusion conditions, with no significant haze expected [3]. - In the Fenwei Plain, haze is expected to gradually weaken and dissipate starting January 29 due to the combined effects of cold air and precipitation [4]. Group 2: Central and Southern Regions - In the Central China region, while air diffusion conditions are generally good, some areas in central and western Hubei and Hunan may experience light haze due to local accumulation and upstream transport [5]. - The Pearl River Delta region is forecasted to have good air diffusion conditions with no significant haze [6]. - In the Southwest region, eastern areas will see more precipitation, leading to better air-clearing conditions, although light haze may occur in parts of the western and southern Sichuan Basin during dry intervals [7]. Group 3: Northern and Northwestern Regions - The Northeast region is expected to have frequent cold air activities, resulting in good air diffusion conditions and no significant haze [8]. - In the Northwest region, the northern slope of the Tianshan Mountains in Xinjiang will have generally poor air diffusion conditions, with light to moderate haze and localized heavy haze, while the southern Xinjiang basin may experience dust weather [9].
