Dynamics of the Typhoon Haitang Related High Ozone Episode over Hong Kong » It has been previously established that photochemical smog occurring in the Pearl River Delta Region (PRD) was associated with stagnant meteorological conditions. However, the photochemical smog (17 July to 20 July 2005) induced by typhoon Haitang was associated with moderate wind speed and nonstagnant meteorological conditions. The dynamic process of this ozone episode was studied using an integrated numerical model, that is, a mesoscale meteorological model and Community Multiscale Air Quality (CMAQ) model. Model performance has been evaluated using both ground-based meteorological and air quality observations. Analysis of simulated wind fields and ozone budget has been performed. This dynamic process is summarized into three physical factors. First, the westerly wind placed Hong Kong directly downwind of the PRD emissions. Second, the convergence of wind flow stimulated a vertical local circulation near the surface layer. This recirculation allowed primary and secondary pollutants to accumulate. Third, the Hindawi.com

Surface Ozone Pattern in Hong Kong » Abstract Surface ozone (O3) and its precursors in rural and urban areas of Hong Kong are analyzed through the seasonal, temporal, and spatial variation patterns. The seasonal O3 shows a unique pattern with a major peak in autumn and a trough in summer. The spring and winter seasons are the transition periods with a relatively small peak in spring. The seasonal alternation of the prevailing oceanic and continental air masses, plus the climate system associated with the Asian monsoon system, are the governing factors for the temporal O3 pattern in Hong Kong. The O3 imported by these air masses is found to be the dominating factor for the fluctuation of ambient O3 in Hong Kong. The aged air masses associated with the continental outflow from China carry with them anthropogenic air pollutants emitted from the blooming industrial and urban neighborhoods north of Hong Kong in Guangdong Province, China. Under favorable meteorological conditions for photochemical O3 formation in southeast China, the O3 level reaches Journals.ametsoc.org
