Equatorial Waves in the Presence of the Equatorial Undercurrent
Equatorial Waves Equatorial Undercurrent
2009/2/13
Because of the narrow region over which it has high speeds, the Equatorial Undercurrent has little effect on long waves with large phase speeds, such as long Kelvin and equatorially trapped inertia-gr...
A Systematic Search for Trapped Equatorial Waves in the GATE Velocity Data
Trapped Equatorial Waves GATE Velocity Data
2009/2/9
Moored current meter data taken over a 60-day period during GATE (GARP Atlantic Tropical Experiment) near the equator at 28°W, have been systematically searched for vertically propagating equatorially...
Deep Currents and Their Interpretation as Equatorial Waves in the Western Pacific Ocean
Deep Currents Western Pacific Ocean Equatorial Waves
2009/2/9
Vertical profiles of current and density made within 5° latitude of the equator along longitudes 168 and 179°E (the vicinity of the Gilbert Islands) reveal multiple deep current reversals which are co...

sea surface temperature El Niñ o Equatorial Waves Air-Sea Thermal Coupling
2009/2/6
Dynamics readjustment of a stratified ocean model to wind perturbations leads to variations in sea surface temperature (SST) related to the early phases of the observed interannual warming of the trop...
Weak Interactions of Equatorial Waves in a One-Layer Model. Part II：Applications
Weak Interactions Equatorial Waves Applications
2009/2/5
There are pairs of resonant triads with two common components. Analytic solutions describing the evolution of a system with such a double resonant triad are presented and compared with the resonant th...

2009/2/5
Dispersive equatorial waves are labeled by the zonal slowness s, the meridional quantum number n and the vertical separation constant c. The slowness (reciprocal of phase speed) is a variable more use...
The Reflection of Equatorial Waves from Oceanic Boundaries
Equatorial Waves Oceanic Boundaries Energy flux
2009/2/5
Theory is developed to discuss the reflection of long equatorial waves from ocean boundaries. The main results are as follows:
1) Energy flux reflection coefficients for the reflection of equatoria...
An analysis is made of the linear waves of the Balance Equations and the global Balance Equations on an equatorial β-plane. We consider both finite and infinite meridional domains and show the effect ...
Equatorial Waves in the Presence of Air-Sea Heat Exchange
Equatorial Waves Air-Sea Heat Exchange free linear waves
2009/2/5
Changes in propagation of free linear waves on the equatorial β-plane associated with air-sea heat exchange are in investigated here. By using a mixed-layer model, with the waves considered as perturb...

2009/2/5
We present results from three numerical model experiments designed to study the thermal and hydrodynamics changes associated with downwelling Kelvin wave passage and east coastal reflection along and ...
Simple, exact analytical conditions for second harmonic resonance between equatorial waves are derived. Such resonance can occur only between two Rossby waves or two westward travelling gravity waves....
It is shown that resonant coupling between ultra long equatorial Rossby waves and packets of either short Rossby or short westward-traveling gravity waves is possible. Simple analytic formulas give th...
