Thermodynamic Feedbacks in Tropical Coupled Variability

Abstract
Air-sea coupling involves the exchange of both momentum and
heat between the atmosphere and the ocean. Dynamic coupling,
which relates to the momentum exchange, is believed to play
the dominant role in the tropics, especially in phenomena such
as the El Nino-Southern Oscillation in the tropical
Pacific. However, thermodynamic heat exchange between the
atmosphere and the ocean can also play a significant role in
air-sea coupling. This is especially true in the tropical
Atlantic, where dynamic coupling may be of secondary
importance. This talk will focus on the use of mechanistic
models to study the role of thermodynamic air-sea coupling
in the tropics.
