The nonlinear evolution of unstable coupled equatorial ocean-atmosphere modes
nonlinear evolution equatorial ocean-atmosphere modes
2009/11/13
In this paper we investigate whether observed intraseasonal variability in the equatorial Pacific can be attributed to finite amplitude waves resulting from unstable air-sea interactions. Within a Zeb...
An infinitely deep stratified ocean on a equatorial beta plane is forced with a periodic wind system. The resulting linearized motion is shown to result in a deep cellular flow structure in rough agre...
Numerical Simulation of Equatorial Ocean Circulation. Part I：A Basic Case in Turbulent Equilibrium
Equatorial Ocean Circulation Turbulent Equilibrium
2009/2/16
An equatorial ocean experiment has been carried out, using the primitive equation model of Semtner and Mintz (1977) with a highly conservative differencing scheme, with high horizontal resolution (Δx ...
Continuously Stratified Models of the Steady-State Equatorial Ocean
Stratified Models Steady-State Equatorial Ocean
2009/2/9
Two linearized, vertically diffusive steady-state models are formulated on an equatorial β-plane. The purpose is (a) to investigate the vertical boundary-layer structure in a continuously stratified o...
Air-Sea Interaction as a Propagator of Equatorial Ocean Surface Temperature Anomalies
Air-Sea Interaction Equatorial Ocean Surface Temperature Anomalies
2009/1/21
The westward propagation of equatorial sea surface temperature anomalies exceeds the surface drift velocity and is probably associated with propagating changes in the depth of the surface mixed layer ...
Solitons in a Continuously Stratified Equatorial Ocean
vertical stratification Pacific Ocean
2009/1/7
The equatorial soliton studies of Boyd are extended to include the effects of continuous vertical stratification. We use vertical profiles of density measured in the equatorial Pacific Ocean and an id...
Analytical Theory of the Steady State Coastal Ocean and Equatorial Ocean
Steady State Coastal Ocean Equatorial Ocean
2009/1/5
Two linear stratified models—a coastal ocean on the f-plane and an unbounded equatorial β-plane—with Rayleigh friction and Newtonian cooling are examined. The problems are analytically tractable and a...
A Statistical Approach to Testing Equatorial Ocean Models with Observed Data
Statistical Approach Observed Data Equatorial Ocean Models
2009/1/4
A model testing procedure based on multivariate statistical analysis has been developed to provide an objective measure of the fit between ocean model simulations and observations, taking into account...
Equatorial Ocean Response to Rapidly Translating Wind Bursts
Equatorial Ocean Response Translating Wind Bursts
2008/12/18
The response of the ocean at low latitude to idealized westerly wind bursts can be described as a wave wake composed of equatorial gravity and Rossby-gravity modes. The excited waves are those with ph...
Sensitivity of the Surface Equatorial Ocean to the Parameterization of Vertical Mixing
Surface Equatorial Ocean Vertical Mixing
2008/12/16
This study investigates the sensitivity of the dynamics of the surface equatorial ocean to the parameterization of vertical mixing. A new high-resolution, numerical model of a zonally independent equa...
Turbulence Decay and Restratification in the Equatorial Ocean Surface Layer following Nighttime Convection
Nighttime Convection Turbulence Decay Equatorial Ocean Surface Layer
2008/11/18
Although the process of restratification of the ocean surface layer at the equator following nighttime convection is similar in many ways to the process at midlatitudes, there are important difference...
Validation of Vertical Mixing in an Equatorial Ocean Model Using Large Eddy Simulations and Observations
Vertical Mixing Equatorial Ocean Model Eddy Simulations
2008/7/8
A nonlocal K-profile parameterization (KPP) of the upper-ocean boundary layer is tested for the equatorial regions. First, the short-term performance of a one-dimensional model with KPP is found to co...
