- Abstract
Based on meteorological field and air quality observation data, air pollution process over Pearl River Delta (PRD) in August of 2012 was analyzed. There were five notable pollution processes in this month, in which four pollution processes were related to typhoon. By using meso-scale meteorological model WRF, meteorological characteristics of two pollution processes induced by tropical cyclone were contrasted and analyzed. Results showed that O3 and PM10 concentrations significantly increased in PRD region during Typhoon Haikui period (7 -8 August), and other pollutant concentrations were also high. However, O3 and PM10 concentrations did not significantly increase during Typhoon Kai-Tak period (16 -17 August). This kind of concentration difference between two processes was related to typhoon pathway, wind direction and velocity, atmospheric boundary layer height, vertical transport and horizontal divergence field.
