中文摘要: 用统计平均方法,分析了天津市250m气象塔1988年冬季和夏季的逐时风速廓线观测资料。结果表明,冬季两种不同性质下垫面上近地层的平均风速廓线统计特征存在着显著性差异。这种差异能够反映出城市建筑群对低层大气风廓线影响的局地气候特征。然而夏季的结果却反映出与冬季不同的统计规律。

Abstract:By means of the statistical averaging method, the hourly observations of wind profile in winter and summer of 1988 obtained from a meteorological tower in Tianjin are analysed.It is found that significant contrast of statistical characteristics for the mean wind profiles in the surface layer exist between them in winter. This contrast may show the feature of the effect of the urban buildings on the wind profiles in lower atmospheric layer on the part of local climate. However, the statistical rulein summer is differed from that in winter.
