Interaction between an Island and the Ventilated Thermocline: Implications for the Hawaiian Lee Countercurrent
Publisher: American Meteorological Society
Abstract: The ventilated thermocline theory is adapted to include the interaction between an island and the wind-driven subtropical circulation. The primary goal is an understanding of the effect of this interaction on the Hawaiian ...
Transmission of Subinertial Kelvin Waves through a Strait
Publisher: American Meteorological Society
Abstract: Solutions are found for the transmission of 1½-layer subinertial Kelvin waves through an ?ideal strait? with parallel channel walls and square corner mouths. This is shown to be a wave interference problem similar to the ...
The Wavenumber–Frequency Content of Resonantly Excited Equatorial Waves
Publisher: American Meteorological Society
Abstract: he theoretical resonant excitation of equatorial inertia?gravity waves and mixed Rossby?gravity waves is examined. Contrary to occasionally published expectations, solutions show that winds that are broadband in both zonal ...
Wavenumber–Frequency Spectra of Inertia–Gravity and Mixed Rossby–Gravity Waves in the Equatorial Pacific Ocean
Publisher: American Meteorological Society
Abstract: n the 1970s and 1980s, there was considerable interest in near-equatorial variability at periods of days to weeks associated with oceanic equatorial inertia?gravity waves and mixed Rossby?gravity waves. At that time, the ...
Response to a Steady Poleward Outflow. Part I: The Linear, Quasigeostrophic Problem
Publisher: American Meteorological Society
Abstract: The response of a zonal channel to a uniform, switched-on but subsequently steady poleward outflow is presented. An eastward coastal current with a Kelvin wave?s cross-shore structure is found to be generated instantly ...
Response to a Steady Poleward Outflow. Part II: Oscillations and Eddies
Publisher: American Meteorological Society
Abstract: A conceptually simple model is presented for predicting the amplitude and periodicity of eddies generated by a steady poleward outflow in a 1½-layer ?-plane formulation. The prediction model is rooted in linear quasigeostrophic ...
Modification of Long Equatorial Rossby Wave Phase Speeds by Zonal Currents
Publisher: American Meteorological Society
Abstract: reviously unaddressed aspects of how equatorial currents affect long Rossby wave phase speeds are investigated using solutions of the shallow-water equations linearized about quasi-realistic currents. Modification of the ...
