Abstract

In December 1973, Peninsular Malaysia and Sarawak experienced a few periods of heavy rain caused by westward moving equatorial vortices from the South China Sea. In this report, the synoptic characteristies associated with the development and intersification of these vortices are shown. Structure of one of the disturbances was examined. Disturbances in the trades associated with lateral shear were found to be important for the genesis of the equatorial vortices. However, the intensification of these disturbances depended on the interaction with the cold monsoon surge.
