Influence of surface wind field convergence on heavily polluted weather

Affect the formation and persistence of heavily polluted weather.

The convergence of ground wind field is a meteorological phenomenon, which means that the wind direction gathers in a certain area to form a strong wind. This kind of strong wind will affect air flow and pollutant diffusion, and aggravate pollutant accumulation. In heavily polluted weather, the convergence of ground wind field will prolong the residence time of pollutants, aggravate the degree of air pollution and affect people's health and quality of life. In the early warning and response of heavily polluted weather, it is necessary to pay attention to the convergence of ground wind fields and take effective measures to reduce its impact.
