Near-Surface Meanders in the Equatorial Indian Ocean
Publisher: American Meteorological Society
Abstract: Drifting buoys were released in the western Indian Ocean from 1979 to 1982. They reveal meanders of the eastward flowing monsoon drift in August?September 1979, 1980 and 1981. Oscillating meridional buoy drifts reach 80 ...
Gyres Driven by Combined Wind and Buoyancy Flux
Publisher: American Meteorological Society
Abstract: The combined effects of buoyancy forcing and wind in a gyre-scale steady ocean circulation are modeled using discrete layers with an interfacial flux, not necessarily vertical. The equations for vorticity conservation of ...
Analysis and Interpretation of Deep Equatorial Currents in the Central Pacific
Publisher: American Meteorological Society
Abstract: Analysis of vertical profiles of absolute horizontal velocity collected in January 1981, February and April 1982 in the equatorial central Pacific revealed two significant narrowband spectral peaks in zonal velocity, ...
Deep Velocity Measurements in the Western Equatorial Indian Ocean
Publisher: American Meteorological Society
Abstract: Vertical profiles of horizontal current collected in April and June 1979 in the western Indian Ocean revealed the presence of short vertical scale (150?300 m) deep zonal jets, trapped to within 1° of the equator. Meridional ...
Equatorial Currents at Semi-Annual Period in the Indian Ocean
Publisher: American Meteorological Society
Abstract: Moored records of zonal velocity in the western equatorial Indian Ocean are dominated by motion of semi-annual period. The motion is coherent over an array spanning more than 1000 km along the equator, 160 km across the ...
Equatorial Velocity Profiles. Part II: Zonal Component
Publisher: American Meteorological Society
Abstract: Vertical profiles of horizontal velocity made along 53°E in the western Indian Ocean, during and after he onset of the southwest monsoon in 1976, show features in zonal velocity of relatively small vertical scale. Persistence ...
A Diagnostic Study of the Northern Atlantic Subpolar Gyre
Publisher: American Meteorological Society
Abstract: A three-layer vorticity diagnostic calculation is made for an area of the northern North Atlantic centered at 55°N, 22.5°W. It suggests the circulation there is not driven by vertical Ekman suction due to the wind stress, ...
How Much Energy Propagates Vertically in the Equatorial Oceans?
Publisher: American Meteorological Society
Abstract: Vertically propagating linear wave calculations using realistic equatorial buoyancy profiles are presented which show the percentage of the downward surface energy flux that reaches the deep equatorial oceans. The percentages ...
Multiple Equilibrium States in Combined Thermal and Saline Circulation
Publisher: American Meteorological Society
Abstract: Structure and stability of the multiple equilibria of the thermohaline circulation am studied using 2 ? 2 and 3 ? 2 box models. Thermohaline catastrophe is a shallow phenomenon and its time evolution consists of three ...
Wind-Forced Variability of Upper Ocean Dynamics in the Central Equatorial Pacific during PEQUOD
Publisher: American Meteorological Society
Abstract: Horizontal currants and dynamic height anomalies measured with a vertical profiler in the central equatorial Pacific during January 1981, February 1982 and April 1982 show significant changes in the upper ocean which are ...
