Presented at the Global Ocean Salinity and the Water Cycle Workshop
Stratification of the upper ocean in the tropics can occur under conditions of a positive heat flux from the atmosphere and/or positive freshwater flux. As such the strength of the stratification and the resulting changes in the surface temperature and salinity are highly sensitive to both the air-sea fluxes and the background initial stratification and mixing. In this talk, I shall discuss observations and modeling of the upper ocean stratification during the SPURS-1 and SPURS-2 field campaigns, including the variation in stratification seen as a result of diurnal warming, freshwater inputs, or both. The resulting mixing and temporal evolution of the stably stratified upper layers will also be discussed.
