摘要
本文基于位于上海浦东国际机场附近的同济大学实测基地获取的2014年台风"娜基莉"影响下的10米高度风数据,研究了"娜基莉"影响下的浦东地区近地风特性。10米高度处风速实测研究表明:纵向的阵风因子明显大于横向和竖向的阵风因子,而横向的阵风因子稍大于竖向阵风因子;各向阵风因子随10min平均风速的增大呈减小的趋势,各向湍流度也随平均风速的增大呈现减小的趋势;纵向湍流度大于横向湍流度,而横向湍流度大于竖向湍流度;各向湍急积分尺度随平均风速的增大而减小。
Based on the Tongji field measurement base near Shanghai Pudong International Airport,the wind dataat 10 meters height under the influence of typhoonNakri in 2014 obtained,then wind characteristics near ground in Pudong area under the influence of typhoon Nakri are studied. Field measurements of the wind speedat 10-meter height show that：the longitudinal gust factors are apparently greater than the horizontal and vertical gust factors,while the horizontal ones are slightly larger than the vertical ones;With the 10min-averaged wind speed increasing ,anisotropy gust factors decrease,so does anisotropy turbulence intensity; The longitudinal turbulence intensity is bigger than the horizontal one, while the horizontal oneis greater than the vertical one;Anisotropy turbulence integral scaledrops with the mean wind speed increasing.
