Abstract

Abstract Moored temperature and profiling conductivity-temperature-depth (CTD) measurements in the upper thermocline during GATE show the presence of an energy peak over the range 2 to 5 cph. These waves have an r.m.s. amplitude of 1 to 2 dbar and are coherent and in phase over the upper 30 m of the thermocline. A model is presented to show how broad-band surface stress forcing can result in an energy peak for frequencies higher than Väisälä frequency Of the thickest constant N layer, the SABININ (1966, Izvestiya, Acadwemy Sciences, U.S.S.R., Atmospheric and Oceanic Physics, English Edition, 2, 872–882) resonance layer.
