RISWater Mass Transformation and Formation in the Labrador Sea
Publisher: American Meteorological Society
Abstract: Objectively analyzed surface hydrographic fields and NCEP?NCAR reanalysis fluxes are used to estimate water mass transformation and formation rates in the Labrador Sea, focusing on Labrador Sea Water (LSW). The authors ...
Changes in the Deep Western Boundary Current at 53°N
Publisher: American Meteorological Society
Abstract: outhward transports in the deep western boundary current across 53°N, over 1949?99, are determined from a historical reconstruction. Long-term mean transports, for given water masses, for net southward transport (the ...
Seasonal and Interannual Variability in a Model of the Mediterranean under Derived Flux Forcing
Publisher: American Meteorological Society
Abstract: A 100-yr integration of a Mediterranean Sea model is performed with surface restoring to monthly varying T, S, followed by 100 years of integration with surface fluxes of heat and freshwater alone. The fluxes are diagnosed ...
Effect of a Variable Eddy Transfer Coefficient in an Eddy-Permitting Model of the Subpolar North Atlantic Ocean
Publisher: American Meteorological Society
Abstract: The effect of using a variable eddy transfer coefficient for the Gent?McWilliams (GM) parameterization in a (1/3)°-resolution ocean model of the subpolar North Atlantic Ocean is investigated. Results from four experiments ...
Warming of the Polar Water Layer in Disko Bay and Potential Impact on Jakobshavn Isbrae
Publisher: American Meteorological Society
Abstract: number of recent studies have shown enhanced retreat of tidewater glaciers over much of southern and western Greenland. One of the fastest retreats has occurred at Jakobshavn Isbrae, with the rapid retreat linked to the ...
The Influence of High-Frequency Atmospheric Forcing on the Circulation and Deep Convection of the Labrador Sea
Publisher: American Meteorological Society
Abstract: he influence of high-frequency atmospheric forcing on the circulation of the North Atlantic Ocean with emphasis on the deep convection of the Labrador Sea was investigated by comparing simulations of a coupled ocean?ice ...
A Diagnostic Barotropic Finite-Element Ocean Circulation Model
Publisher: American Meteorological Society
Abstract: The finite-element method possesses many advantages over more traditional numerical techniques used to solve systems of differential equations. These advantages include a number of conservation properties and a natural ...
JEBAR, Bottom Pressure Torque, and Gulf Stream Separation
Publisher: American Meteorological Society
Abstract: A diagnostic, finite element, barotropic ocean model has been used to simulate the mean circulation in the North Atlantic. With the inclusion of the joint effect of baroclinicity and relief (JEBAR), the Gulf Stream is found ...
Assimilation of Argo Temperature and Salinity Profiles Using a Bias-Aware EnOI Scheme for the Labrador Sea
Publisher: American Meteorological Society
Abstract: AbstractIn this study, temperature and salinity profiles from Argo floats are assimilated into a coupled ice?ocean model over the North Atlantic Ocean and Arctic using an ensemble optimal interpolation (EnOI) scheme, with ...
Role of Resolved and Parameterized Eddies in the Labrador Sea Balance of Heat and Buoyancy
Publisher: American Meteorological Society
Abstract: eep convection in the Labrador Sea is an important component of the global ocean ventilation. The associated loss of heat to the atmosphere from the interior of the sea is thought to be mostly supplied by mesoscale eddies, ...
