Abstract:

In order to evaluate the ability of a high resolution Pacific-Indian basin ocean general circulation model to simulate the climatology and inteannual variability, we analyzed preliminarily the simulation results of the model in this paper, and compared them with the ocean assimilation data set and previous research works. Analyses show that the simulation results of SST distribution, structure of equatorial thermocline and zonal current, distributional pattern of equatorial current system, spatial distribution characteristics of SSH and barotropic stream function and El Nino and La Nina events are approximate to that of SODA ocean assimilation data set. Besides, the seasonal and interannaul variability of the North Equatorial Current (NEC) bifurcation agrees well with the previous study. Furthermore, our study reveal that the latitude of NEC bifurcation and Luzon Strait transport are intimately associated with ENSO cycle on the interannual timescale.

Key words: North Equatorial Current (NEC) bifurcation, Luzon Strait transport, climatology, interannual variability, high resolution model
