本文利用中国120个探空站一年所有探空气球漂移信息，从漂移距离、漂移地域、漂移速度等方面开展分析。分析结果显示，年平均漂移距离随着高度的增加，漂移距离一般呈增大的趋势，并且在500hPa到100hPa之间漂移现象十分明显，年平均每100hPa漂移约10km；冬、春季漂移大，夏、秋季漂移小，纬向的变化幅度远大于经向的变化幅度；整体上气球漂移的年平均速度均小于2km/min，气球漂移速度从地面到对流层顶呈递增趋势，到了对流层顶漂移速度达到最大，过了对流层顶漂移速度逐渐减小，各月漂移速度变化趋势基本一致，漂移速度从小到大为6月、7月、8月、9月、5月、10月、4月、11月、12月、3月、1月、2月；纬向整体上为向西的漂移，最大纬向漂移速度达到3km/min，经向漂移速度3月-8月与其它月份变化趋势基本呈反相变化，漂移速度最大达到0.4km/min。

Based on the balloon floating data from all 120 upper-air sounding stations in China in 2004 the floating distance,mean floating velocity,floating regional distribution and floating drive source are analyzed.The results show that the floating distance has increasing trend with increasing height,obvi-ous floating occurs between 500hPa and 100hPa,and its annual mean floating distance can reach to 10km per 100hPa.floating distance in winter and spring is bigger than that in summer and autumn,and the latitude floating change amplitude of is far bigger than longitude.The mean annual floating velocity shows increas-ing trend from surface to troposphere,and reach to maximal value of 2km/min at troposphere,then shows decreasing trend.All months own similar floating velocity change trend that can be ranked as June,July, August,September,May,October,April,November,December,March,January and February from small value to big value.The latitude floating is wholly westward and the maximal latitude floating velocity can reach to 3km/min,the longitudinal floating velocity change trend from March to August shows opposite change trend of the others months and the maximal longitudinal floating velocity can reach to 0.4km/min.
