Photochemical modeling and analysis of meteorological parameters during ozone episodes in Kaohsiung, Taiwan

摘要: Abstract The events of high ozone concentrations and meteorological conditions covering the Kaohsiung metropolitan area were investigated based on data analysis model simulation. A photochemical grid was employed to analyze two episodes in autumn (2000) winter (2001) seasons, each three consecutive days (or 72 h) City. potential influence initial boundary performance assessed. Model can be improved by separately considering daytime nighttime lateral domain. sensitivity analyses emission reductions volatile organic compounds (VOC) nitrogen oxides (NOx) show a VOC-sensitive regime for lower than 30–40% VOC 30–50% NOx NOx-sensitive larger percentage reductions. Meteorological parameters that warm temperature, sufficient sunlight, low wind, surface pressure are distinct tend trigger polluted urban areas, like Kaohsiung.
