The Bureau of Meteorology has run a version of the WAM model, AUSWAM, for the past15 years. The recent significant changes to the forcing winds with the implementation of the Australian Community Earth System Simulator (ACCESS) system has prompted theevaluation of the WAVEWATCH III®model as a possible replacement.
The implementation of WAVEWATCH III® within the Bureau of Meteorology's forecasting environment is known as AUSWAVE. This report documents the testing and verificationof the AUSWAVE model. The benefits that this model offers over AUSWAM are describedand the error characteristics of both models are compared.
A number of hindcasts are performed over a four month period from July to October 2008.Verifications are carried out against both altimeter data and buoy data around the Australiancoast, with the aim of identifying the most suitable configuration for the Australian region.This set up is then compared with AUSWAM.
AUSWAVE is found to provide clear and immediate improvements over the AUSWAMmodel, showing forecast skill gains of 36 h to 48 h lead time for significant wave height. Anegative bias is present in AUSWAVE. This is due primarily to a low bias in the ACCESS.
