Steady Coastal Circulation Due to Oceanic Alongshore Pressure Gradients
Publisher: American Meteorological Society
Abstract: A depth-averaged barotropic model is used to investigate the steady response of the coastal ocean to alongshore pressure gradients imposed by the deep ocean. Solution indicate that the dimensionless continental margin width ...
Low-Frequency Trapped Waves an a Wide, Reef-Fringed Continental Shelf
Publisher: American Meteorological Society
Abstract: The properties of low-frequency waves, trapped on a wide, reef-fringed continental shelf are predicted theoretically and compared with limited observations from the northeast coast of Australia. A theoretical model of free ...
Obliquely Incident Poincaré Waves on a Sloping Continental Shelf
Publisher: American Meteorological Society
Abstract: An analytical theory of barotropic tides propagating onto a sloping continental shelf from the deep ocean is developed. The plane Poincaré waves incident from the deep ocean are obliquely angled, and a full matching of ...
Modeling the East Australian Current in the Western Tasman Sea
Publisher: American Meteorological Society
Abstract: The East Australian Current (EAC) is a western boundary current flowing southward off the east coast of Australia. Its eddy variability has been shown to be vigorous, a typical feature being the formation of a large warm ...
Geostrophic Pumping, Inflows and Upwelling in Barrier Reefs
Publisher: American Meteorological Society
Abstract: The communication between shallow and deep oceans via gaps in the separating barrier reefs is examined using a simplified two-layer analytical model. Attention is focused on the flow resulting from a sea-level difference ...
Local and Remote Wind Forcing of New South Wales Inner Shelf Currents and Sea Level
Publisher: American Meteorological Society
Abstract: Linear multiple regression analysis is used to identify the locally and remotely wind-driven components of the nearshore current and adjusted sea level (ASL) variability at Sydney, New South Wales. The data analyzed comprise ...
Wind-forced Motion on the Northern Great Barrier Reef
Publisher: American Meteorological Society
Abstract: Observations of current, bottom pressure, and wind from the shelf of the Northern Great Barrier Reefare interpreted using a two-layer, frictional, step-shelf model forced by propagating wind stress. Distinguishing features ...
Coastal-Trapped Waves behind a Large Continental Shelf Island, Southern Great Barrier Reef
Publisher: American Meteorological Society
Abstract: The salient features of subinertial frequency fluctuations of current, sea level, temperature and wind stress observed within the Capricornia section of the Great Barrier Reef are interpreted by comparison with coastal-trapped ...
On Wavenumber Estimates for Forced Continental Shelf Waves
Publisher: American Meteorological Society
Abstract: We derive expressions that predict the variations of Cartesian, rotary and elliptical properties of free and forced barotropic continental shelf waves as functions of alongshore and cross-shore location. Bottom friction ...
Steady Wind-Driven Coastal Circulation on a β-Plane
Publisher: American Meteorological Society
Abstract: In tropical regions, and for applications where the alongshore scale k?1 of the forcing is large, the assumption of constant Coriolis parameters f in Csanady's Arrested Topographic Wave (ATW) model is invalid. Here we ...
