Abstract EN
Due to the distinct geographical and meteorological conditions of Taiwan, air pollutants concentrations in the ambient air of it may vary with seasons.
Accordingly, this study aimed to investigate the formation of high O3 concentration in the ambient air of Southern Taiwan during summers.
A high O3 concentration case occurring between June 28 and July 2, 2013, was modeled and analyzed with WRF-Chem meteorological and air quality model.
During the investigated period, a typical western Pacific subtropical high (WPSH) covered most East Asia, including Taiwan and its surrounding areas.
The observations showed strong correlations between WPSH invasion and forming high O3 concentrations.
The dispersion of air pollutants in the ambient air is not sufficient to dilute their concentrations.
In the afternoon of June 30, more than 60% of the air quality monitoring stations found O3 concentrations exceeding 100 ppb, which were 2~3 times higher than their normal concentrations.
Model simulation results verified that the presence of the WPSH hindered the dilution and transportation of air pollutants in ambient air.
In addition, the air quality would be getting worse due to the leeward sides caused by the counter clockwise vertex formed in Southwestern Taiwan.
