摘要

Abstract

Observational data obtained during the TOGA-COARE IOP in the “warm pool” area of the Western Tropical Pacific were used to analyze some characteristics of the intraseasonal variations in the mixed layer. The influence of westerly burst and rainfall on SST

salinity and mixed layer depth are discussed. There are two pairs of counteracting processes in the “warm pool” mixed layer: (1) The increase of mixed layer depth caused by local westerly bursts and the decrease of mixed layer depth caused by larger scale easterly relaxation; (2) the vertical mixing by local wind and the strong stratification due to rainfall in the mixed layer. Some possible mechanisms through the interactions between the intraseasonal time scale variations of the oceanic mixed layer and atmospheric low frequency oscillations are revealed.
