Comparison of Surface Wind Stress Anomalies over the Tropical Pacific Simulated by an AGCM and by a Simple Atmospheric Model

In this paper, surface wind stress anomalies over the tropical Pacific simulated by an AGCM and by a simple at-mospheric model are compared with observed. The AGCM is the higher resolution global spectral model-COLA R40 model and the simple atmospheric model is the atmospheric component of the Cane-Zebiak coupled ocean-at-mosphere model The results show that the wind stress anomalies simulated by both the COLA R40 and the simple model have captured the main features of observation but the x component in the CZ model is closer to that in observation than that in the COLA model, and the correlation coefficients between simulated SSTA from the CZ model and observed for Nino indices are higher than those from the COLA model.
