摘　　要：根据臭氧、气象探空观测数据,分析了1996年7月5日至8月3日西宁（36°44’N,101°45＇E,海拔高度2296m）上空对流层臭氧垂直分布变化与气象要素之间的关系。对流层臭氧浓度的增加（减少）总伴随着干、冷（暖、湿）气流的输送变化,而这又与大气垂直方向的运动是紧密联系在一起的。分析表明天气动力输送过程对对流层臭氧垂直分布变化有重要作用。The variations in vertical distribution of tropospheric ozone and their associations with meteorological ete-ments have been analyzed based on the observations made by using ozonesondes and rawinsondes during the period of July 5-August 3, 1996 over Xining (36°44'N, 101°45'E, 2296 m above sea Level). Increase (decrease) of ozone concentration in troposphere is always accompanied by the dry, cold (warm,moist) air flow, and this is much related to the vertical movement of atmosphere. Our results illustrate that the synoptic process has significant impact on the variations of ozone vertical distribution in troposphere.
