RISOn the Generalized Eigenvalue Problem for the Rossby Wave Vertical Velocity in the Presence of Mean Flow and Topography
Publisher: American Meteorological Society
Abstract: n a series of papers, Killworth and Blundell have proposed to study the effects of a background mean flow and topography on Rossby wave propagation by means of a generalized eigenvalue problem formulated in terms of the ...
Generalized Patched Potential Density and Thermodynamic Neutral Density: Two New Physically Based Quasi-Neutral Density Variables for Ocean Water Masses Analyses and Circulation Studies
Publisher: American Meteorological Society
Abstract: n this paper, two new quasi-neutral density variables?generalized patched potential density (GPPD) and thermodynamic neutral density ?T?are introduced, which are showed to approximate Jackett and McDougall empirical neutral ...

The Quasi-Nondispersive Regimes of Long Extratropical Baroclinic Rossby Waves over (Slowly Varying) Topography
Publisher: American Meteorological Society
Abstract: Actual energy paths of long, extratropical baroclinic Rossby waves in the ocean are difficult to describe simply because they depend on the meridional-wavenumber-to-zonal-wavenumber ratio τ, a quantity that is difficult ...
Comments on “Diathermal Heat Transport in a Global Ocean Model”
Publisher: American Meteorological Society
Abstract: AbstractHolmes et al. (2019) have proposed a new theoretical framework for studying ocean heat uptake in potential temperature coordinates. One important step in their derivations requires understanding the temporal changes ...
On the Local View of Atmospheric Available Potential Energy
Publisher: American Meteorological Society
Abstract: AbstractThe possibility of constructing Lorenz?s concept of available potential energy (APE) from a local principle has been known for some time, but it has received very little attention so far. Yet the local APE density ...
The Effect of Bottom Pressure Decoupling on the Speed of Extratropical, Baroclinic Rossby Waves
Publisher: American Meteorological Society
Abstract: In layered models of the ocean, the assumption of a deep resting layer is often made, motivated by the surface intensification of many phenomena. The propagation speed of first-mode, baroclinic Rossby waves in such models ...
Acceleration, Creation, and Depletion of Wind-Driven, Baroclinic Rossby Waves over an Ocean Ridge
Publisher: American Meteorological Society
Abstract: The influences of topography on the propagation, spatial patterns, and amplitude variations of long baroclinic Rossby waves are investigated with a wind-forced, two-layer model above a midocean ridge. With steep topography ...
The Key Role of the Western Boundary in Linking the AMOC Strength to the North–South Pressure Gradient
Publisher: American Meteorological Society
Abstract: key idea in the study of the Atlantic meridional overturning circulation (AMOC) is that its strength is proportional to the meridional density gradient or, more precisely, to the strength of the meridional pressure gradient. ...
The Life Cycle of the North Atlantic Storm Track
Publisher: American Meteorological Society
Abstract: he North Atlantic eddy-driven jet exhibits latitudinal variability with evidence of three preferred latitudinal locations: south, middle, and north. Here the authors examine the drivers of this variability and the variability ...
