Abstract
Equatorial regions are characterized by significant interannual variability in oceanographic processes that are linked to changes in climate throughout the globe (Rassmusson and Wallace, 1983). Due in part to their role in global climate variability, equatorial regions—and particularly the equatorial Pacific—have received considerable attention from meteorologists and physical oceanographers during past decades. Recent measurements made during National Oceanographic and Atmospheric Administration (NOAA)-sponsored programs such as the Equatorial Pacific Ocean Climate Studies (EPOCS) and the Tropical Ocean Global Atmosphere (TOGA), as well as National Science Foundation (NSF)-sponsored programs such as Tropic Heat, have led to significant advances in our understanding of the oceanographic processes at work in the equatorial Pacific.
