This study presents analysis of the Tropical Instability Waves in the Atlantic. Using the temperature, salinity, and velocity data from the PIRATA mooring at 0N, 23W we argue that the baroclinic and barotropic energy conversions are equally important in feeding energy to TIWs if the wave-induced salinity fluctuations are taken into account.  Whole story
