On the Alaskan Stream
Publisher: American Meteorological Society
Abstract: The Alaskan Stream boundary current south of the uniformly curving coastline formed by the Alaskan peninsula-Aleutian Island chain is examined analytically via steady, barotropic frictional theory. It is shown that, as a ...
The Attenuation of Vertically Propagating Internal Gravity Waves by a Randomly Varying Wind/Current Shear
Publisher: American Meteorological Society
Abstract: We consider the effect of a randomly varying horizontal advective flow on internal gravity waves propagating vertically in a nonrotating, stratified and unbounded fluid. Attention is focused on the alteration in the vertical ...
A Cyclonic Eddy over the Continental Margin of Vancouver Island Evidence for Baroclinic Instability
Publisher: American Meteorological Society
Abstract: This paper describes the circulation, water properties and energetics of an observed cyclonic eddy that formed over the continental margin of Vancouver Island between late July and early September, 1980. The eddy was ...
Steric Sea Level Trends in the Northeast Pacific Ocean: Possible Evidence of Global Sea Level Rise
Publisher: American Meteorological Society
Abstract: Thirty-year time series of hydrographic observations from Ocean Station PAPA and Line ?P? are used to estimate secular trends in monthly mean steric sea level heights relative to depths of 100 and 1000 decibars in the ...
Bottom-trapped Subinertial Motions over Midocean Ridges in a Stratified Rotating Fluid
Publisher: American Meteorological Society
Abstract: Linear analytical solutions for bottom-trapped subinertial oscillatory flow over simple ridge topographies in a stratified (two-layer) rotating fluid are presented. Results are compared to moored current meter observations ...
A Diagnostic Model for Mixed Layer Depth Estimation with Application to Ocean Station P in the Northeast Pacific
Publisher: American Meteorological Society
Abstract: This paper presents a simple diagnostic model for estimating mixed layer depth based solely on the one-dimensional heat balance equation, the surface heat flux, and the sea surface temperature. The surface fluxes drive ...
Three-Dimensional Model Simulations of Tides and Buoyancy Currents along the West Coast of Vancouver Island
Publisher: American Meteorological Society
Abstract: A three-dimensional finite element model is used to calculate the barotropic tides and seasonal buoyancy flows off the western and northern coasts of Vancouver Island. The model buoyancy currents and the harmonics of eight ...
M2 Baroclinic Tides in Johnstone Strait, British Columbia
Publisher: American Meteorological Society
Abstract: Tide, current and water property data collected in the western basin of Johnstone Strait, British Columbia, are compared with analytical models for M2 semidiurnal motions in a stratified, rotating channel of uniform depth. ...
Evidence of Diurnal Shelf Waves in Satellite-Tracked Drifter Trajectories off the Kuril Islands
Publisher: American Meteorological Society
Abstract: Satellite-tracked surface drifters deployed in September 1993 in the vicinity of the Kuril?Kamchatka Trench were advected onto the Pacific continental shelf of the Kuril Islands where they encountered strong (40?50 cm s?1) ...
Coastal Countercurrent and Mesoscale Eddy Formation by Tidal Rectification near an Oceanic Cape
Publisher: American Meteorological Society
Abstract: Cape St. James is an extensive triangular-shaped promontory located in a tidally energetic region at the southern tip of the Queen Charlotte Islands approximately 150 km off the mainland coast or British Columbia. Several ...
