Abstract: Zebiak-Cane Ocean Model (ZC) is a moderate complex Model for Sea-atmosphere coupling in Tropical Pacific. Since its development in the middle of 1980s, the ZC model has been used widely in the ENSO forecast, ENSO theory and predictability research. During 1995-2000,Chen et al. has made some technical forecast improvements to the Model mainly in the initialization scheme of the coupled-modeling and the correction of statistics bias. The model initialization scheme is, mainly adopting the Nudging method, to assimilate the SSTA and Sea Surface Height. In the past researches, the work of using observing data to improve the model’s subsurface parameterization scheme is limited.
Using the temperature profiling data of Argo floats (2001-2003) and the TAO floats (1980-2003), we make an assessment of the ZC model’s subsurface later temperature scheme.
