Abstract
Abstract A primitive equation, three-dimensional, baroclinic circulation model has been configured for use in the North Indian Ocean. After having been spun up by climatological winds, the model was used to generate a hindcast for 1993–95 under synoptic forcing, both with and without assimilation of multichannel sea surface temperature (MCSST) and altimetric sea surface height (SSH) anomaly data. Without data constraints, the model captures many of the salient oceanographic features in this region including equatorial surface and subsurface currents, the Laccadive High Eddy, the Great Whirl, and the reversing Somali Current. However, assimilation of altimetric data enables it to depict these features more accurately. MCSST data enable the near-surface layers to be simulated more accurately. The National Aeronautics and Space Administration TOPEX precision altimeter has provided oceanographers with an important tool to study the variability in the circulation of the world’s oceans. The availability of SSH ...
