Abstract

The seasonal sea level variability of the northwest African upwelling area is investigated using altimetric data from TOPEX/POSEIDON and ERS-1 missions. The combined sea surface height profiles, provided by both missions, reveal the seasonal variations of the mid to outer shelf sea surface topography, in response to wind-driven coastal circulation. The sea level variability observed demonstrates the known coastal upwelling variability along the study area. Comparisons are carried out using wind and sea surface temperature (SST) data. Better agreement is observed with the SST data than the wind-based estimated Ekman transport.
