Abstract | In this study, the outputs from Weather Research and Forecasting (WRF) regional climate model that has beendynamically downscaled the ECHAM5 Global Climate Model was used to investigate the regional climate change impact on airqualityrelated meteorological conditions in upper northern Thailand. The analyses were compared between the future (20452064) and present (19902009) of the downscaled climate results. The meteorological variables that can potentially affect theregional air quality include temperature, planetary boundary layer height (PBLH), wind speed and ventilation index wereanalyzed during the majority air pollution season (haze season, January-April) in the study area. It was found that increase in Tmaxcan cause the increase of pollution sources while the increase in Tmin, causing the reduction of the vertical dispersion potential ofpollutants, and yielding a favorable meteorological condition for pollutant accumulation. The surfaces wind and PBLH werepredicted decreasing during air pollution season in the future, leading weaker ventilation rate in this region. |
