Book Description
An important issue presented here is the existence of two different types of correlation between time rate of change of sea surface temperature (SST) partial derivative Tau/partial derivative tau and the ocean mixed-layer (OML) depth h(omega), depending on the ocean surface conditions. In the tropics, the net heat flux (including radiation budget) at the ocean surface is generally downward and dampens the OML turbulent kinetic energy (TKE). As the ocean surface is under weak wind forcing, the OML shallows to the Monin-Obukhov length scale due to insufficient wind-generated TKE to entrain the deep cool water into the OML. Net heat gain at the ocean surface and very little heat loss at the OML base leads to a warming OML. The thinner the OML, the warmer the OML. Therefore, partial derivative Tau/partial tau and h(omega) are negatively correlated; however, as the ocean surface is under strong wind forcing, the OML deepens due to sufficient wind-generated TKE to entrain the deep cool water into OML. The excessive heat loss at the OML base (entrainment heat flux) over net heat gain at the ocean surface leads to a cooling OML. The thicker the OML, the warmer the OML. Therefore, partial derivative Tau/partial derivative tau and h(omega) are positively correlated. The shift of positive-only correlation between partial derivative Tau/partial derivative tau and h(omega) (as conventionally thought to be), to two-way correlation leads to a new theory about the interannual tropical ocean-atmosphere interaction. To investigate the impact of this new idea on the interannual tropical ocean-atmosphere interaction, an Air- Ocean Surface Heat Exchange (AOSHE) Model, which is a coupled system consisting of the Wind-Induced Surface Heat Exchange (WISHE) Model (Yano and Emanuel) and the Ocean Mixed-Layer (OML) Model (Chu and Garwood) has been developed. The major advantage of the AOSHE model is simple but contains realistic thermodynamics in both ocean and atmosphere.
Generation of Low-Frequency Unstable Modes in a Coupled Equatorial Troposphere and Ocean Mixed-Layer Model
P-Vector Inverse Method
Author: Peter C. Chu
Publisher: Springer Science & Business Media
ISBN: 354033386X
Category : Science
Languages : en
Pages : 610
Book Description
A major task for physical oceanographers is to determine the movement of oceanic water from observations. This book introduces the P-vector inverse method, with a two-step determination of the velocity from hydrographic data. The book provide insights into the basics of the P-vector inverse method and the features of the inverted global and regional ocean circulations. Upper undergraduate and graduate students as well as oceanographers, marine biologists and other environmental scientists will find this book a valuable tool for their studies.

Book Description
The ocean mixed layer and clouds are coupled by the fluxes of momentum, heat, and water mass at the interface. The importance of the fluxes of momentum and heat is well recognized by both meteorologists and oceanographers. However, the water mass flux has been given considerable attention only in atmospheric models since the latent heat release is an importance source of energy for the atmospheric general circulation. The water mass flux is given less attention in ocean models although it is realized that evaporation and precipitation contribute to the surface buoyancy flux which influences the depth of mixing and the thermohaline circulation.
