The Agulhas Current System During the Northeast Monsoon Season
Agulhas Current System Northeast Monsoon Season
2009/3/7
Data specifically selected from the total available data set have been used for an isentropic analysis of the southwest Indian Ocean. Components of geostrophic velocity at the depths of the various is...
Topographically Induced Changes in the Structure of an Inertial Coastal Jet:Application to the Agulhas Current
Inertial Coastal Jet Agulhas Current
2009/2/13
Calculations are made of the changes in the structure of an inertial current which can be induced by slow changes in the topography of the continental shelf and slope along which it flows. The particu...
Asymptotic Analysis of the Agulhas and Brazil Current Systems
Asymptotic Analysis Agulhas Brazil Current Systems
2009/2/7
An asymptotic analysis is carried out of a linear and a nonlinear transport model of the large-scale wind-driven ocean circulation in the subtropical region of the Atlantic and Indian Oceans. The comp...
A description of the nature and kinematics of the Agulhas Current termination is given based on satellite infrared imagery and selected hydrographic measurements collected over the past decade. On ave...
Dynamics of Agulhas Retroflection and Ring Formation in a Numerical Model. Part II. Energetics and Ring Formation
Agulhas Retroflection Ring Formation
2009/1/5
An energetics analysis of several numerical experiments on an idealized South Atlantic-Indian Ocean basin is presented. The model used in the experiments is the quasi-isopycnic coordinate model of Ble...
Dynamics of Agulhas Retroflection and Ring Formation in a Numerical Model. Part I:The Vorticity Balance
Agulhas Retroflection Ring Formation Vorticity Balance
2009/1/5
The Agulhas retroflection region of the wind-driven idealized South Atlantic–Indian Ocean model described by DeRuijter and Boudra is analyzed in detail. Here, in Part I, the physical mechanisms of the...
Seasonal Variations in the Region of the Agulhas Retroflection:Studies with Geosat and FRAM
Fine Resolution Antarctic Model Agulhas Retroflection
2008/12/19
In this paper seasonal variations in the Agulhas Retroflection region are studied by analyzing data from the radar altimeter, flown on the Geosat satellite, and output from the Fine Resolution Antarct...
Agulhas Eddies:A Synoptic View Using Geosat ERM Data
Exact Repeat Mission sea surface height Agulhas Eddies
2008/12/11
Warm core rings formed in the, Agulhas Retroflection transfer water from the Indian Ocean to the South Atlantic. In an attempt to measure the strength of this exchange, a combination of satellite alti...
Numerical Study of the Agulhas Retroflection:The Role of Bottom Topography
Bottom Topography Agulhas Current
2008/12/10
The oceanic circulation near the eastern margin of the African continent is dominated by the poleward flow of the Agulhas Current. The Agulhas Current separates from the African coast near the souther...
A series of numerical experiments with a two-layer primitive equation model is presented to study the dynamics of Agulhas eddies. The main goal of the paper is to examine the influence of an underwate...
Stability of Western Boundary Currents with an Application to Pulselike Behavior of the Agulhas Current
Western Boundary Currents Pulselike Behavior Agulhas Current
2008/7/31
The northern Agulhas Current off South Africa displays very steady flow characteristics. Roughly five to six times per year the flow is disrupted by the passage of large solitary meanders, propagating...
