Numerical experimentation of a diagnostic model of 3-D circulation in the Arabian Sea

Abstract

Climatic circulation in the upper levels of the Arabian Sea and western equatorial Indian Ocean are computed using a 3-dimensional, 33 level diagnostic circulation model. A steady state solution is obtained within 30 days of model integration. Model has been successful in computing all the major current systems in the Arabian Sea and western equatorial Indian Ocean during NE and premonsoon seasons. Computed currents are compared with available observations on currents at selected regions in the model area and it has been found that both agreed fairly well. Model results are also explained in terms of the forcing parameters and the dynamics considered in the model.
