On a Recent Parameterization of Mesoscale Eddies
Publisher: American Meteorological Society
Abstract: A recent parameterization of mesoscale eddies by Gent and McWilliams (GMc) represents their effects as advective and diffusive fluxes along isopycnals. The form chosen for the added transport velocity due to eddies flattens ...
Geostrophic Adjustment and Restratification of a Mixed Layer with Horizontal Gradients above a Stratified Layer
Publisher: American Meteorological Society
Abstract: The restratification of a mixed layer with horizontal density gradients above a stratified layer is considered. Solutions are obtained on the assumption that the width across this front is much larger than the local radius ...
Secondary Instabilities in Langmuir Circulations
Publisher: American Meteorological Society
Abstract: Finite-amplitude Langmuir circulation in the form of rolls parallel to the wind direction is shown to be subject to three-dimensional instability under certain circumstances. Density stratification is not required for ...
Quantifying the Role of Mixed Layer Entrainment for Water Mass Transformation in the North Atlantic
Publisher: American Meteorological Society
Abstract: Forcing by wind stress and air?sea buoyancy flux climatologies between σt = 23.5 and 26.5 results in differing water mass transformations in the North Atlantic, reflecting the opposing tendencies of wind stress and air?sea ...
Lateral Mixing in the Pycnocline by Baroclinic Mixed Layer Eddies
Publisher: American Meteorological Society
Abstract: sing a process study model, the effect of mixed layer submesoscale instabilities on the lateral mixing of passive tracers in the pycnocline is explored. Mixed layer eddies that are generated from the baroclinic instability ...
Diurnal Restratification Events in the Southeast Pacific Trade Wind Regime
Publisher: American Meteorological Society
Abstract: his paper describes the occurrence of diurnal restratification events found in the southeast trade wind regime off northern Chile. This is a region where persistent marine stratus clouds are found and where there is a less ...
Reabsorption of Lee-Wave Energy in Bottom-Intensified Currents

Spontaneous Generation of Near-Inertial Waves by the Kuroshio Front
Publisher: American Meteorological Society
Abstract: hile near-inertial waves are known to be generated by atmospheric storms, recent observations in the Kuroshio Front find intense near-inertial internal-wave shear along sloping isopycnals, even during calm weather. Recent ...
