RISNOTE ON FINITE-DIFFERENCE APPROXIMATIONS FOR THE VISCOUS GENERATION OF VORTICITY AT A BOUNDARY
Publisher: American Meteorological Society
Abstract: The viscous decay of a fluid in solid body rotation in a circular two-dimensional container is studied using a vorticity finite-difference scheme. A comparison is made with the well-known analytic solution to determine the ...
A Numerical Model of Convection Driven by a Surface Stress and Non-Uniform Horizontal Heating
Publisher: American Meteorological Society
Abstract: This paper examines the two-dimensional convective motion of a nonrotating incompressible Boussinesq fluid heated non-uniformly from below. The fluid container is rectangular; the side and top boundaries are insulating and ...
A Comparison of Some Shallow Wind-Driven Currents
Publisher: American Meteorological Society
Abstract: Four sets of current measurements made in water depths ranging between 28 and 38 m over periods ranging from three to five weeks are examined and compared. The response of the water column to wind forcing is examined by ...
On the Mean Circulation in the Mid-Atlantic Bight
Publisher: American Meteorological Society
Abstract: Two possible mechanisms which may drive the observed mean alongshelf flow in the Mid-Atlantic Bight are described. Runoff from concentrated sources could conceivably force this flow; however, the one-layer homogeneous model ...
Winter Circulation in the Western Gulf of Maine: Part 2. Current and Pressure Observations
Publisher: American Meteorological Society
Abstract: The wintertime circulation in the western Gulf of Maine has been studied with a moored current, temperature and pressure array which was deployed from November 1974 to January 1975. These observations have been interpreted ...
An Observation of Frontal Wave Development on a Shelf-Slope/Warm Core Ring Front Near the Shelf Break South of New England
Publisher: American Meteorological Society
Abstract: Small-scale waves have been observed near 40°N, 68°30?W in specially enhanced satellite imagery of a strong temperature front formed in May 1979, between the shelf/slope-water front and warm core ring 79-B. Thew frontal ...
The Marine Layer off Northern California: An Example of Supercritical Channel Flow
Publisher: American Meteorological Society
Abstract: During the spring and summer, northerly winds driven by the North Pacific high pressure system are prevalent over the Northern California continental shelf, only interrupted for periods of a few days, when weak or southerly ...
Response Characteristics of the VACM Compass and Vane Follower
Publisher: American Meteorological Society
Abstract: Several simple laboratory experiments have been conducted to study the dynamic behavior of the vector-averaging current meter (VACM) compass and vane follower. They demonstrate that the behavior of the compass and vane ...
A Modified Beam-to-Earth Transformation to Measure Short-Wavelength Internal Waves with an Acoustic Doppler Current Profiler
Publisher: American Meteorological Society
Abstract: The algorithm used to transform velocity signals from beam coordinates to earth coordinates in an acoustic Doppler current profiler (ADCP) relies on the assumption that the currents are uniform over the horizontal distance ...
Using MM5 to Hindcast the Ocean Surface Forcing Fields over the Gulf of Maine and Georges Bank Region
Publisher: American Meteorological Society
Abstract: The fifth-generation Pennsylvania State University?NCAR Mesoscale Model (MM5) is applied to the Gulf of Maine/Georges Bank (GoM/GB) region. This model is configured with two numerical domains with horizontal resolutions ...
