Why There is an Intense Eastward Current in the North Atlantic but not in the South Atlantic
Publisher: American Meteorological Society
Abstract: It is suggested that baroclinic currents may he expected to he sharper where deeper water or a decreasing Coriolis parameter lies in the direction of the Coriolis force. This is the case for the Gulf Stream between Hatteras ...
A Prograde Jet Driven by Rossby Waves
Publisher: American Meteorological Society
Abstract: Waves are forced by moving sources and sinks of mass on a beta-plane with Ekman friction. If the motion is retrograde and not too fast, these are Rossby waves with a nonzero Reynolds stress u?v??. This stress forces a ...
Climatological Numerical Models of the Surface Mixed Layer of the Ocean
Publisher: American Meteorological Society
Abstract: Three slab models of the surface mixed layer of the ocean are given simple and fast computer implementations. Actual meteorological data from Ocean Weather Station N are used for a year-long forecast. The results compare ...
Observations of the Leeuwin Current off Western Australia
Publisher: American Meteorological Society
Abstract: Shipboard observations made in May 1982 showed a definite poleward surface flow (the Leeuwin Current) over the West Australian shelf from 22°S to 28°S. The surface current was relatively fresh, warm, low in dissolved oxygen ...
Low-Pass Filters to Suppress Inertial and Tidal Frequencies
Publisher: American Meteorological Society
Abstract: A systematic way is given to design digital filters which allow clear separation of signals with periods of a few days from noise of higher frequency, particularly tidal and inertial. Several examples are given which pass ...
Wind-Driven Circulation in a Fjord
Publisher: American Meteorological Society
Abstract: Currents, temperature, salinity, wind, runoff and water level were observed for a month in the J?sen-fjord of southern Norway. Tide gages and currents show little semidiurnal tide. There is a strong diurnal signal in the ...
Shortcomings of an Objective Analysis Scheme
Publisher: American Meteorological Society
Abstract: A currently used objective analysis scheme was tested by comparing a known function to an objective analysis of its values at the locations of radiosonde observing stations. A surface spherical harmonic of wavenumber 2 ...
