An intermediate atmosphere-ocean coupled model appropriate for the study of El Nin~o has been developed. The model is not only economic to use but also contains several most important physical processes. The geometrical effects which were not consided in the previous intermediate model study of Ahn (1990), are included in the model for more realistic simulation of the event. The results show hat the individual models respond appropriately to the given boundary conditions. At the same time, in the coupled model experiment, ENSO-like oceanic and atmospheric anomalies are also well simulated under an external triggering similar to the initiation forcing of ENSO. It is expected that this type of model can be effectively used for the study and simulation of El Nin~o. More improvement of modeling may be possible after inclusion of subsequent processes such as inclusion of ocean mixed layer dynamics.
