An Analysis of Wind-Driven Ocean Circulation with a Limited Number of Fourier Components
Publisher: American Meteorological Society
Abstract: The equations of motion for a square ocean basin of dimension L on the ?-plane are solved approximately for the case where a wind-strew curl of the form sin (x/L) sin (y/L)[0≤x,y≤πL] is applied to the surface. The stream ...
Circulation Driven by Winds and Surface Cooling
Publisher: American Meteorological Society
Abstract: A three-layer model of ocean circulation in a Northern Hemisphere basin is driven by winds that are anticyclonic in the south and cyclonic in the north. The ocean is also driven by surface cooling, which is parameterized ...
Obtaining Velocities from Tracer Distributions
Publisher: American Meteorological Society
Abstract: A simple advective-diffusive system with uniform, horizontal flow in a channel and fixed boundary concentrations of two tracers is analyzed for the tracer concentrations in the interior. The deduced concentrations are then ...
Determining Velocities and Mixing Coefficients from Tracers
Publisher: American Meteorological Society
Abstract: The effort to determine oceanic velocities from tracer distributions relies on a knowledge of the effects of mixing. However, the macroscopic diffusion coefficient, K, is generally not known and must be calculated along ...
Circulation and Heat Flux in the Bermuda Triangle
Publisher: American Meteorological Society
Abstract: Data from the Atlantis 215 cruise from Cape Henry to Bermuda to Fort Pierce is analyzed to determine absolute geostrophic velocities in the region. The search procedure that Fiadeiro and Veronis (1982) proposed for finding ...
Solving Underdetermined Tracer Inverse Problems by Spatial Smoothing and Cross Validation
Publisher: American Meteorological Society
Abstract: Tracer conservation equations may be inverted to determine the flow field and macroscopic diffusion coefficients from known tracer distributions. An underdetermined system leads to an infinite number of possible solutions. ...
