The Malaysian Meteorological Department,

This verification study is done for the Erb West platform, an oil and gas exploration site, located at latitude 6.3 ° North and longitude 115.4 ° East, approximately 83 km west-northwest of Kota Kinabalu, Sabah. The forecast data used in this study are surface wind speeds (WSPD) taken from the Global Forecast System (GFS), while the significant wave heights (SWH) and wave periods (WPRD) are from the Malaysian Meteorological Department Wave prediction Model (MMD WAM). These modeled data are then compared against the observed from the instruments at the platform for the period from 1st January 2010 until 31st December 2010. The bias and root-mean-square errors (rmse) for the 24-hr, 48-hr, 72-hr and 96-hr forecasts are then analyzed and scatter diagrams are plotted. The temporal error variability and temporal evolution of rsme are plotted. The model error for SWH between-0.26 and 0.27 meters, are comparable to the T/P altimeter accuracy (smaller than 0.5 m), which indicates the the capability of MMD WAM model in predicting the SWH at Erb West Platform. The GFS model is not perform well in predicting the WSPD at Erb West platform
