Abstract
An upwelled region as seen through satellite imagery off the Somali coast is compared with sea surface temperature during summer Monex-79. The relationship between satellite-derived low-level cloud drift winds and the sea-surface temperature is studied. Cloudiness associated with a prime eddy off the Somali coast is also studied. It is observed that the upwelled region has a unique crescent shape and reflects the sea-surface temperature that is driven by low-level strong winds. The prime eddy, as observed through a satellite imagery, shows that low cloud convection tends to be greater over the warm waters of the prime eddy, and the upwelled cold water tends to encircle the eddy leading to the identification of its outer boundary.
