RISThe Role of Mesoscale Eddies in the Source Regions of the Agulhas Current
Publisher: American Meteorological Society
Abstract: A primitive equation model to study the dynamics of the Agulhas system has been developed. The model domain covers the South Atlantic and the south Indian Ocean with a resolution of ?° in the Agulhas region while coarser ...
Multidecadal Indian Ocean Variability Linked to the Pacific and Implications for Preconditioning Indian Ocean Dipole Events
Publisher: American Meteorological Society
Abstract: AbstractThe Indian Ocean has sustained robust surface warming in recent decades, but the role of multidecadal variability remains unclear. Using ocean model hindcasts, characteristics of low-frequency Indian Ocean temperature ...
The Sensitivity of the Greenland–Scotland Ridge Overflow to Forcing Changes
Publisher: American Meteorological Society
Abstract: Processes that influence the volume and heat transport across the Greenland?Scotland Ridge system are investigated in a numerical model with ?° horizontal resolution. The focus is on the sensitivity of cross-ridge transports ...
Contribution of Increased Agulhas Leakage to Tropical Atlantic Warming
Publisher: American Meteorological Society
Abstract: he upper tropical Atlantic Ocean has markedly warmed since the 1960s. It has been shown that this warming was not due to local heat fluxes and that the trade winds that drive the coastal and equatorial upwelling have ...
Instability-Driven Benthic Storms below the Separated Gulf Stream and the North Atlantic Current in a High-Resolution Ocean Model
Publisher: American Meteorological Society
Abstract: AbstractBenthic storms are important for both the energy budget of the ocean and for sediment resuspension and transport. Using 30 years of output from a high-resolution model of the North Atlantic, it is found that most ...
Vertical Velocity Dynamics in the North Atlantic and Implications for AMOC

Causes of Interannual–Decadal Variability in the Meridional Overturning Circulation of the Midlatitude North Atlantic Ocean
Publisher: American Meteorological Society
Abstract: The causes and characteristics of interannual?decadal variability of the meridional overturning circulation (MOC) in the North Atlantic are investigated with a suite of basin-scale ocean models [the Family of Linked Atlantic ...
Agulhas Leakage Predominantly Responds to the Southern Hemisphere Westerlies
Publisher: American Meteorological Society
Abstract: he Agulhas Current plays a crucial role in the thermohaline circulation through its leakage into the South Atlantic Ocean. Under both past and present climates, the trade winds and westerlies could have the ability to ...
Decoupling of the Agulhas Leakage from the Agulhas Current
Publisher: American Meteorological Society
Abstract: he relationship between the Agulhas Current and the Agulhas leakage is not well understood. Here, this is investigated using two basin-scale and two global ocean models of incrementally increasing resolution. The response ...
Pacific Ocean Contribution to the Asymmetry in Eastern Indian Ocean Variability
Publisher: American Meteorological Society
Abstract: ariations in eastern Indian Ocean upper-ocean thermal properties are assessed for the period 1970?2004, with a particular focus on asymmetric features related to opposite phases of Indian Ocean dipole events, using ...
