本研究用中央氣象局十多年的臭氧探空資料，分析平流層和對流層臭氧的季節變化，以及長期趨勢。同時量度的氣象因子使得分析更有意義。由對流層頂高度的逐漸提昇，每十年＋79±206公尺；及溫度小幅但顯著地下降，每十年減少1.0 ± 0.89K，顯示臺灣上空大氣已感受到溫室效應氣體增加的影響。對流層臭氧是由地表積分各高度的臭氧分壓而得，有不顯著的微弱下降，每十年減少0.60 ± 2.1DU，雖然與許多人預測不符，但是和近一二十年全球各地觀測結果沒有太大差異。臭氧垂直剖面在低平流層有很顯著的變化：夏季有遠多於平均的臭氧，冬季則比平均值少很多。對流層的變化幅度較平流層小：冬季多而夏季少，冬夏季節變化正好與平流層相位相反。春秋兩季的臭氧則沒有明顯的特徵。比較同時期臭氧及溫度直垂剖面的年季變化，發現臭氧與溫度變化在某段時差下，兩者呈負相關，因此大氣動力所引起氣溫改變可能是控制臭氧季節性分布的主要因素。臭氧的長期趨勢，在低平流層有顯著增加，在中高對流層則有明顯下降。臭氧的趨勢變化正與溫度變化明顯反相。這現象應該表示對流層的增溫縮短了臭氧在大氣的生命期，因此濃度下降。在低對流層溫度下降，使得臭氧生命期變長，濃度上昇。當然在某地觀測到的臭氧變化及趨勢，不一定能代表更廣泛的區域。本觀測結果雖僅在臺北，但是與部份模式推估有許多相似之處，如果這�媃[察到的現象也在其他地區發生，未來對流層臭氧的量的增加將不如許多人預期的多，而地表的增溫幅度也較許多人預期低許多。

　　　　　This study analyzes the ten-year ozonezonde data taken by the Central Weather Bureau from 1993 till 2002. With concurrent observations of meteorological information, results are quite interesting. There is an insignificant rise in the tropopause heights, +79 ± 206 m per decade. Temperature at the tropopause decreases at rate of 1.0±0.89K per decade. Both are signs of troposphere warming. Values of tropospheric ozone are obtained by integrating the observed ozone partial pressure from surface up to the tropopause. This data set gave an insignificant decreasing trend of -0.60 ± 2.1 DU per decade. Ozone profiles have distinct seasonal and annual variations. There are more than averaged ozone in the lower stratospheric summer, and less than average during winter. Variations in the troposphere are the opposite, more in the winter and less in the summer. Comparing with variations of temperature, there are negative correlations at same heights or different heights. These suggest the dynamic process drive the temperature change which in turn influence the ozone distribution in the atmosphere. It is more obvious when trend of ozone profiles compare with that of temperature, in lower stratosphere and troposphere. It is suggested that temperature change caused by global warming affect ozone vertical distribution. Due to highly variability of ozone, observations at one location may not be able to represent wider region. However, results from this study do match those predictions from GCM driven chemistry models. It suggests the importance of climate forcing on the ozone distribution in this area, and may explain the missing tropospheric ozone increase, and predict a much smaller warming from tropospheric ozone.
