RISA Model of the Equatorial Sea Surface Temperature Field and Associated Circulation Dynamics
Publisher: American Meteorological Society
Abstract: A linear, continuously stratified analytical model of the equatorial ocean is developed and used to simulate the major features of the equatorial sea surface temperature (SST) field and current system. The model is bounded ...
Dynamics of the Block Island Sound Estuarine Plume
Publisher: American Meteorological Society
Abstract: uoyant discharge of freshwater from Long Island Sound (LIS) forms a seasonal buoyant plume outside Block Island Sound (BIS) between the coast of Long Island and the denser shelf waters. The plume?s seasonal variability and ...
Modeling the Oceanic Response to Westerly Wind Bursts in the Western Equatorial Pacific
Publisher: American Meteorological Society
Abstract: A 3D tropical upper-ocean circulation model is employed to study the generation mechanism for subsurface reversing currents forced by strong westerly wind bursts in the western equatorial Pacific. The westerly wind bursts ...
Exact Solutions to Kawase's Linear Model of Deep Ocean Circulation
Publisher: American Meteorological Society
Abstract: Exact solutions are found for Kawase's linear, two-layer model of mass-driven deep-ocean circulation. It is demonstrated that for strong damping, even though the deep western boundary current (DWBC) bifurcates at the equator ...
A Hybrid Vertical Mixing Scheme and Its Application to Tropical Ocean Models
Publisher: American Meteorological Society
Abstract: A novel hybrid vertical mixing scheme, based jointly on the Kraus?Turner-type mixed layer model and Price's dynamic instability model, is introduced to aid in parameterization of vertical turbulent mixing in numerical ocean ...
The Annual Cycle of SST in the Eastern Tropical Pacific, Diagnosed in an Ocean GCM
Publisher: American Meteorological Society
Abstract: The annual onset of the east Pacific cold tongue is diagnosed in an ocean GCM simulation of the tropical Pacific. The model uses a mixed-layer scheme that explicitly simulates the processes of vertical exchange of heat and ...
Wind Forced Wave–Mean Flow Interactions in the Equatorial Waveguide. Part I: The Kelvin Wave
Publisher: American Meteorological Society
Abstract: A numerical model is designed to study the effects of the strong, near-surface associated with the equatorial current system on energy transmission of time-periodic equatorial waves into the deep mean. The present paper ...
Interior Reflections of a Periodically Forced Equatorial Kelvin Wave
Publisher: American Meteorological Society
Abstract: A fully three-dimensional, wind-forced equatorial model is used to study the effects of the strong near- surface equatorial pycnocline on energy transmission into the deep ocean. The equatorial Kelvin waves forced by a ...
Seasonal Variability of the South Equatorial Current Bifurcation in the Atlantic Ocean: A Numerical Study
Publisher: American Meteorological Society
Abstract: In this study, a reduced-gravity, primitive equation OGCM is used to investigate the seasonal variability of the bifurcation of the South Equatorial Current (SEC) into the Brazil Current (BC) to the south and the North ...
A Numerical Investigation of the Local Ocean Response to Westerly Wind Burst Forcing in the Western Equatorial Pacific
Publisher: American Meteorological Society
Abstract: Numerical simulations of the local equatorial ocean response to idealized westerly wind burst (WWB) forcing are described. In particular, the authors examine the development and evolution of the subsurface westward jet ...
