ABSTRACT
Knowledge in the Indonesian archipelago regarding information about wave height is very important to support activities in the sea. Given this, the accuracy of wave height forecasts needs attention. This study aims to determine the performance of ocean wave predictions from ECMWF (The European Center for Medium-Range Weather Forecasts) data on satellite altimeter observation data.The location of the study was located in the area of North Java Sea waters, the results of the wave characteristics analysis from 2016-2018 and the analysis of wind variables in 2016-2018 to waves in the Java North Sea waters were examined to determine the wave height change parameters.Wave counts are generated from processing using the Sverdup Munk Bretschneider (SMB) method. With data obtained from ECMWF (The European Center for Medium-Range Weather Forecasts) and data verified using Wind data from BMKG. Wind data are analyzed in each season, namely the west, east and transition seasons. From the results and analysis of altimetry satellite elevation data quality to field data explain that the verification of wave height (H) data from ECMWF with Field data obtained an RMSE value of ± 0,262 m.
