Abstract

The purpose of this study is to enhance the accuracy of numerical wave forecast with data assimilation. The present paper is to investigate the potential use of the spectral observations from the pitch-and-roll buoys which supply measurements in nearreal- Time for assimilation in an operational forecast system. And how to do optimal interpolation when we only have one buoy on deep ocean will be discussed in this study. And then, the impact of the assimilation of those measurements on the wave analysis and forecast is studied over several typhoon periods in 2006, by comparing runs with and without assimilation.
