Core Viewpoint - The article discusses the impact of cold air and strong winds on air quality across various regions in China, leading to dust storms and haze conditions in several areas. Group 1: Weather Impact - From January 13 to 14, regions including central and western Inner Mongolia, western Gansu, Ningxia, and northern Shaanxi will experience dust or floating dust due to strong winds from cold air [1] - From January 13 to 15, southern and central parts of North China and western Huanghuai will see slightly deteriorated air diffusion conditions, with light haze in some areas and moderate haze locally [1] - The upcoming week will see poor air diffusion conditions in the northern slope of the Tianshan Mountains and the Sichuan Basin, with light to moderate haze, and heavy haze in some local areas [1] Group 2: Regional Forecasts - In the Beijing-Tianjin-Hebei region, air diffusion conditions will be generally average, with light haze in some areas from January 13 to 15 [2] - The Yangtze River Delta region will also have generally average air diffusion conditions, with intermittent light haze in the northern part [3] - The Fenwei Plain will experience generally average air diffusion conditions, with light haze in the Guanzhong area of Shaanxi during cold air intervals [4] - The Central China region will have generally average air diffusion conditions, with intermittent light haze in the northern part [5] - The Pearl River Delta region will have generally good air diffusion conditions, with no significant haze [6] - The Southwest region, particularly the Sichuan Basin, will see poor air diffusion conditions with light to moderate haze, and heavy haze in some local areas [7] - The Northeast region will have good air diffusion conditions due to active cold air, with no significant haze [8] - The Northwest region, particularly the northern slope of the Tianshan Mountains, will experience light to moderate haze, with heavy haze in some local areas, and dust or floating dust in parts of Inner Mongolia, Gansu, Ningxia, and northern Shaanxi from January 13 to 14 [9]
