What is the fog in Wuhan?

The atmospheric state in Wuhan is stable, the wind speed is low, and the humidity is high, which leads to the inversion phenomenon, which is not conducive to the smoke diffusion in the near-surface layer, the accumulation of particulate matter, and the formation of a sunshade layer. The sunlight refracts and reflects in pollutants for many times, which leads to the sky being khaki, resulting in the smog weather in Wuhan. Haze source analysis: Through meteorological monitoring and analysis, there are a lot of haze weather in Anhui and Henan wheat harvest areas, and the northeast wind from North China to the middle reaches of the Yangtze River is 8- 12m/s, which is beneficial to the transport of harmful particles from north to south. At the same time, the surrounding area of Wuhan, Hubei Province is a divergent settlement area, and harmful particles transported at high altitude sink in Wuhan area. Coupled with the high humidity and sufficient water vapor near the bottom, today's smog weather is formed.
