Data analysis using a 3-year PM2.5 concentration, air pollutants found leeward will be easily accumulated Xi Nanbu eddy currents and generate a transmission as vortex effect changes.
Using 3 years of data analysis of PM2.5 concentration changes, it was found that air pollutants were affected by the leeway vortex and tended to accumulate in the southwest and have transmission effects as the vortex changed.
Using three years' data to analyze PM2.5 concentration change, it is found that air pollutants will be easily accumulated in the southwest under the influence of leeward vortex and produce transmission effect with the change of vortex.<br>
