Abstract
In this thesis I have endeavored to determine the factors and physical processes
that controlled SST and thermocline depth at 10°N, 125°W during the Pan American
Climate Study (PACS) field program. Analysis based on the PACS data set,
TOPEX/Poseidon sea surface height data, European Remote Sensing satellite wind
data, and model simulations and experiments reveals that the dominant mechanisms
affecting the thermocline depth and SST at the mooring site during the measurement
period were local surface fluxes, Ekman pumping, and vertical mixing associated with
enhancement of the vertical shear by strong near-inertial waves in the upper ocean
superimposed upon intra-seasonal baroclinic Rossby waves and the large scale zonal
flow.
