中文摘要：
通过对热带风暴（TC）“黄蜂”登陆的一次边界层观测所得到风速资料的分析计算，取得不同时距下平均风速序列。比较不同时距选取时登陆TC的平均风速、风向和台风强度，发现1min平均比10min平均水平最大风速大25．30％，风向变化不大，TC强度指数1min与10min相差2％～4％。时距选取较小时，TC平均风速和强度变大，所测得风速区域也变大，而风向与时距的选取没有明显关系。只是在阵风变化比较大的情况下选取小的时距可以更好的表示这种特征。所以时距选取需要对所研究问题的需要进行分析，对不同的问题选取不同的时距以得到更好的结果。
英文摘要：
Based on the boundary layer observation data of typhoon ＇ Vongfong＇ , we get wind speed of different time-distance in this paper. According to comparison among the mean wind velocity, wind direction, typhoon intensity of landing typhoon, it is found that the mean horizontal velocity per 1 min is 25.30% larger then that of 10 min, also the avg. vertical velocity, the range of velocity, the typhoon intensity tend to increase with the time-distance decrease. But the wind direction doesn＇t show significant relation to the time-distance. Generally, the problem of time-distance selection needs to be further studied to get better average wind speed data.
