SPECIFICATION OF HURRICANE WIND FIELDS FOR OCEAN WAVE PREDICTION

摘要

A procedure to blend wind fields obtained from NCEP's operational AVN global atmospheric model and GFDL hurricane model for single and multiple tropical cyclones over the ocean has been developed. Blended wind fields are used in NWW3 wave model for predicting Western North Atlantic waves during the hurricane season of the year 2000. The resulting products, both winds and waves, are compared with data obtained from instruments on NDBC buoys. It shows that using blended wind fields provide more realistic wave fields over the areas within hurricane influence than just using AVN winds only.
