Application of MASNUM Wave Model in Indo Pacific Ocean and its Verification using Altimeter Data

A long time series of ocean wave in-situ observations is rare and mostly unavailable. An urgent demand for a long time series of ocean wave hindcast and prediction makes attention is shifted to the use of numerical wave model. Wave spectral models then used to generate and estimate the ocean wave. A wave spectral model, MASNUM, was set up to carry out wave hindcast experiments in the Indian Ocean and western Pacific. The model has been run for 6 years and validated by comparing the results with altimeter data from Jason-1. A various statistical methods have been employed to quantify the validation. The lateral boundary is influenced to large error in the model. The RMSE can be reduced about 0.4 m after rejected the lateral boundary. The error is larger in boreal winter than that in boreal summer.
