RECONSTRUCTION OF WIND STRESS ANOMALIES SIMULATED BY AN AGCM USING SVD TECHNIQUE

Systematic errors in the COLA R15 AGCM are analyzed by the SVD technique.In order to remove or reduce this kind of error source and reduce climate drift in coupled runs a way in which the wind stress anomalies simulated by an AGCM are reconstructed is proposed by using SVD analsis.Experimental results show that not only wind stress anomalies simulated by an AGCM are obviously improved by reconstructed wind stress anomalies but also this reconstruction has a function of a low-pass time filter,as a result,response of the ZC ocean model to reconstructed wind stress anomalies is more realistic than that of simulated wind stress anomalies by an AGCM.In this paper,application of the hybrid couple ocean-atmosphere model is further discussed.
