摘　　要：通过选取全球海域23个代表性波浪浮标观测数据验证FHDI全球平常浪数学模型(Global Normal Wave Model,简称FHDI-GNWM)的主要指标精度,结果表明:模型计算波高验证结果较好,满足预设目标;模型计算波周期与浮标实测波周期的相关系数普遍较低,但是分布特征高度一致。与NOAA、OWI、ECMWF、BMT、DHI等国际知名全球波浪数学模型的基于浮标实测数据的精度检验指标参数进行对比,结果表明:以上所有全球波浪数学模型波高验证均比较好,但波周期均存在相关系数较低、离散度较大等现象,周期验证需要结合Hs-Tp散点图、波周期玫瑰图/频率分布图等进行总体分布特征评价。In this paper,the accuracy of the main indicators of the FHDI Global Normal Wave Model(FHDI-GNWM)isverified by selecting the observation data of 23 representative wave buoys in the oceans over the world.The results show that theverification results of wave heights calculated with model are good and meet the preset target.The correlation coefficientbetween the wave periods calculated with the model and the wave periods measured at the buoys is generally low,but thedistribution characteristics are highly consistent.Compared with the accuracy test index parameters of wave mathematicalmodels by internationally renowned bodies such as NOAA,OWI,ECMWF,BMT,and DHI based on buoy measured data,theresults show that all the above global wave mathematical models have better wave height verification,but the wave periods tendto have low correlation coefficient and large dispersion,therefore,the verification of wave periods needs to combineHs-Tp scatter plot,wave period rose diagram/frequency distribution figures,etc.to evaluate the overall distribution.
