Abstract
This paper examines the multi-level, primitive equation, global ocean circulation
model of Semtner and Chervin for its ability to simulate the seasonal cycle in the tropical
Pacific Ocean. The result of a 20-year integration of this model using annual mean wind
forcing was reported in Semtner and Chervin (1988). This was the first global eddyresolving
ocean calculation and it showed many realistic features of ocean circulation.
The phase of the simulation analyzed in this report incorporates seasonally varying wind
forcing from the Hellerman and Rosenstein (1983) global data set. These wind stress
values were defined on a grid with 2° spacing which have been interpolated to the onehalf
degree grid points of the Semtner and Chervin model. There is no interannual
variability in the wind fields of this data set. The results presented here are from the fourth year of a 10-year seasonal cycle run.
