Abstract:
Motivation: A better simulation of ENSO is one of major target in the coupled ocean-atmosphere GCM modeling study. The coupled models may capture some aspects of the observed ENSO. However, the diversity of the model ENSOs has been known for quite some time. It is quite unknown what causes the diversity of the model ENSOs. Thus, the proposed study attempts to identify what intrinsic dynamics of each model play a dominant role to drive the tropical Pacific interannual variability. Method: Analyze the thermal budget in the ocean mixed layer (SST) appeared in CGCM outputs associated with ENSO. For the thermal budget, the 3-dimensional advections and the surface heat fluxes are calculated.
