英文摘要A high-resolution tropical pacific general circulation model (gcm) coupled to a global atmospheric gcm is described in this paper. the atmosphere component is the 5 degrees x 4 degrees global general circulation model of the institute of atmospheric physics (iap) with 9 levels in the vertical direction. the ocean component with a horizontal resolution of 0.5 degrees, is based on a low-resolution model (2 degrees x 1 degrees in longitude-latitude). simulations of the ocean component axe first compared with its previous version. results show that the enhanced ocean horizontal resolution allows an improved ocean state to be simulated; this involves (1) an apparent decrease in errors in the tropical pacific cold tongue region, which exists in many ocean models, (2) more realistic large-scale flows, and (3) an improved ability to simulate the interannual variability and a reduced root mean square error (rmse) in a long time integration. in coupling these component models, a monthly "linear-regression" method is employed to correct the model's exchanged flux between the sea and the atmosphere. a 100-year integration conducted with the coupled gcm (cgcm) shows the effectiveness of such a method in reducing climate drift. results from years 70 to 100 are described. the model produces a reasonably realistic annual cycle of equatorial sst. the large ssta is confined to the eastern equatorial pacific with little propagation. irregular warm and cold events alternate with a broad spectrum of periods between 24 and 50 months, which is very realistic. but. the simulated variability is weaker than the observed and is also asymmetric in the sense of the amplitude of the warm and cold events.
