收集了2005年台风形成相关的92天气象参数（风速、风向和混合高度）和空气污染物浓度（O3、NO和NO2）的地面数据。台风对O3浓度的影响以方位角和距台湾的距离来划分，A、B和C型分别对应于距台湾小于1,500 km，方位角介于45°和135°之间、135°和225°之间和225°和45°之间的台风。D型对应于距离台湾1,500公里以上的台风。滴定反应在三个时间段进行：2000-0700、0800-1100和1200-1400 LST（当地标准时间）。利用大气污染模式（TAPM）模拟了风场和气团的运动轨迹。结果表明，台风位置对O3浓度、O3滴定的时空分布和垂直气象特征均有影响，但均未达到统计显著水平。
Surface data of meteorological parameters (wind speed, wind direction, and mixing height) and air pollutant concentrations (O3, NO, and NO2) were collected for a 92-day period associated with typhoon formation in 2005. The influence of typhoons on O3concentration were defined by azimuth and distance from Taiwan, and Types A, B, and C correspond to typhoons less than 1,500 km from Taiwan and located between azimuths 45° and 135°, 135° and 225°, and 225° and 45°, respectively. Type D corresponds to typhoons more than 1,500 km from Taiwan. Titration reactions were conducted at three temporal phases: 2000–0700, 0800–1100, and 1200–1400 LST (Local Standard Time). The air pollution model (TAPM) was used to simulate wind fields and trajectories of air masses. It was determined that typhoon position affected O3concentration, temporal and spatial patterns of O3titration and vertical meteorological characteristics, which were not all at the statistically significant level.
