Effect of Synoptic Scale Weather Disturbance to Philippine Transboundary Ozone Pollution using WRF-CHEM

Gerry Bagtasa

Abstract—Air pollution is not only caused by local emission but also by atmospheric pollutants being transported from the surrounding region. This study examines the impact of the downdraft at the edge of a long-lived typhoon system Parma on the transport of atmospheric pollution from the main Asian continent to the Philippines using the fully coupled Weather Research and Forecast - Chemistry (WRF-CHEM) regional air quality model. On the first week of October 2009, typhoon Parma became virtually stationary at the northern tip of the Philippines as it interacted with typhoon Melor via the Fujiwara effect, producing a rare northwest wind that provided a transport path for the pollutants. The simulation of Nitrogen Oxides (NOx: including NO and NO2) and Ozone (O3) showed that gaseous NOx do not travel very far while the secondary pollutant O3 underwent long range transport.

Index Terms—transboundary pollution, air quality modeling, tropospheric ozone, wrf-chem.
