摘　　要：本文用日本气象厅浮标站于1974年至1996年期间在台风作用下所测得的4000余条含有风与浪等要素资料进行分类统计,给出了估算台风下波高、风速与台风特征参数关系的直接统计结果。进而对最严重的两类台风浪波高与相应的风速等参数间关系用回归分析法和无因次化分析法作探讨,提出了两种估算台风浪波高的实用方法,并用实测检验了后一种方法,基本符合。This paper presents some results of a study,in which the data associated with typhoons during years of 1974-1996 from 'Ocean Data Buoy Stations of Japan Meteorological Agency' are processed by using statistical methods.As the first part,there are mean values of wind speed,wave height and period in each class of data which is yielded by classifying the data according to typhoons central pressure P0 and the distance from observation point (Buoy) to the typhoon center r and the azimuth angle from the direction of movement of the typhoon center.Then,in order to derive the empirical relationship among the significant wave height,wind speeds and other parameters under typhoons the regression analysis and dimen-sionless analysis are carried out to deal with two sets of the severest data composed from several classes of the classified data respectively.Two proposed equations derived by dimensionless analysis may be used to predict conveniently significant wave height due to typhoons by using the wind speed V10 and the distance r. The equations are tested by previously published field data in South China Sea and found to be in general agreement.
