摘要将海流计测量的潮流与新西兰地区正压潮汐模型的输出进行了比较。对于半日分潮，M2潮和S2潮的一致性非常好。对于昼夜成分（KI，OI），它被发现，作为组件的振幅降低，所以没有模型/观测协议和观测到的潮汐椭圆参数的准确性。因此，无法确定差异是由于模型或数据的缺陷造成的。然而，该模型作为海洋潮流模拟的预测工具的整体性能似乎是好的。
Abstract Tidal currents derived from current meter measurements are compared with the output from a barotropic tidal model of the New Zealand region. For the semi‐diurnal constituents there was very good agreement for the M2 tide and good agreement for the S2 tide. For the diurnal constituents (Kl, Ol) it was found that as the amplitude of the constituents decreased so did both the model/observation agreement and the accuracy of the observed tidal ellipse parameters. Consequently it was not possible to decide whether differences arose through shortcomings in the model or in the data. However, the overall performance of the model as a prognostic tool for ocean tidal current simulation appears to be good.
