Abstract: | The response of the Sao Paulo Continental Shelf (SPCS) to synoptic wind forcing has been analyzed. Two different methods are
used for this purpose, one based on hydrographic data, bottom topography, and geographical characteristics, and a second on
analyzing currentmeter data directly and using empirical orthogonal functions. Both methods show similar results for an essentially
barotropic shelf. The SPCS response in the subinertial frequency band appears to be trapped on the continental shelf. Numerical
experiments have also been carried out showing results that qualitatively agree with the observations, including the velocity
component parallel to the coastline.
