RISOn Ocean Spindown I: A Linear Experiment
Publisher: American Meteorological Society
Abstract: The spindown of an ocean is investigated, using a two-layer numerical model. At the initial instant, a pool of warm water the size of the Coral Sea occupies the subtropical portion of the top layer; the pool is initially ...
Indian Ocean Intraseasonal Variability in an Ocean General Circulation Model
Publisher: American Meteorological Society
Abstract: The impact of atmospheric intraseasonal variability on the tropical Indian Ocean is examined with an ocean general circulation model (OGCM). The model is forced by observation-based wind stresses and surface heat fluxes ...
The Sverdrup Relation in the Indian Ocean, and the Effect of Pacific-Indian Ocean Throughflow on Indian Ocean Circulation and on the East Australian Current
Publisher: American Meteorological Society
Abstract: The observed distribution of the depth-integrated steric height (mass transport function) in the Indian Ocean compares favorably with the distribution computed from the Sverdrup relation and annual average wind stresses, ...
Estimation of Errors in Seasonal Cycles
Publisher: American Meteorological Society
Abstract: A formula is first given for the error in a 2-harmonic seasonal curve of best fit through a set of N oceanographic data points, assuming the departures from the true mean are independent random numbers. Departures of actual ...
The Large-Scale Environment of the Poleward-Flowing Leeuwin Current, Western Australia: Longshore Steric Height Gradients, Wind Stresses and Geostrophic Flow
Publisher: American Meteorological Society
Abstract: Steric heights have been estimated using T?S relationships for all available XBTs within 10?40°S, 105?130°E to 1980, and merged with steric heights from hydrology data. These data were subdivided into bins following the ...
The Role of Indonesian Throughflow in a Global Ocean GCM
Publisher: American Meteorological Society
Abstract: The effect of the Indonesian Throughflow on the World Ocean circulation is examined by a series of experiments with a global ocean GCM. The principal objective is to gain an understanding of how ocean flows respond to the ...
Observations of Low Richardson Numbers and Undercurrents near a Front in the East Australian Current
Publisher: American Meteorological Society
Abstract: A surface current jet with speeds in excess of 1.5 m s?1 was found flowing southward and out to sea, off the northern New South Wales coast; such jets are commonly occurring features of the region. Estimates of surface ...
Observations of the Shelf-Edge Current South of Australia, Winter 1982
Publisher: American Meteorological Society
Abstract: Results are presented from an oceanographic cruise along Australia's south coast in June?July 1982. A narrow shelf-edge current flowed eastwards along the shelf edge for the entire distance. Features of particular interest ...
Why Does the Indonesian Throughflow Appear to Originate from the North Pacific?
Publisher: American Meteorological Society
Abstract: Most available wind products show a mean wind stress curl across the Pacific at 2°N that is close to zero, so a Sverdrup model predicts the western boundary current at the Asian coast to be nearly zero at this latitude. ...
