STUDY OF TRANSVERSE JETS OF THE BENGUELA UPWELLING FROM SATELLITE DATA

Analysis of daily satellite IR images of the region of the Benguela up welling (15-32 degrees S) acquired during two sea expeditions in Janua ry-February 1986 and in April-June 1988 established the existence of a system of cold and warm transverse jets and determined the fundamenta l characteristics of these. The geographical positions of the jets and their interconnection with the topography of the sea bed were analyse d. Correlation between the space-time variability of the system of col d jets and the seasonal intensification of the upwelling was establish ed. Mechanisms for the generation of the upwelling jets are discussed.
