Abstract: We have used linear quasigeostrophic dynamics to calculate the motion, decay and dispersion rates of radially symmetric initial disturbances with scales appropriate to Gulf Stream Rings. Baroclinic rings translate westward ...

Abstract: One of the serious flaws in the standard quasi-geostrophic equations, commonly used for understanding the evolution of mesoscale eddies, is the requirement that the change in thickness between density surfaces must be small ...

Abstract: In this paper it is proposed that baroclinic instability of even a weak shear may play an important role in the generation and stability of the strong zonal jets observed in the atmospheres of the giant planets. The ...

Abstract: ow-frequency oceanic motions have banded structures termed ?striations.? Since these striations embedded in large-scale gyre flows can have large amplitudes, the authors investigated the effect of mean flow on their ...

Abstract: Estimates of the repeatability and accuracy of XBT measurements were made using XBT data taken during MODE. The XBT observations of the depth of isotherms had systematic errors of up to 15 decibars (by comparison to ...

Abstract: An analytical theory is presented for the self-induced translation of an intense vortex relative to a uniform background flow on the ? plane. The equivalent barotropic approximation is used to formulate the initial value ...

Abstract: his paper studies the interaction of an Antarctic Circumpolar Current (ACC)?like wind-driven channel flow with a continental slope and a flat-bottomed bay-shaped shelf near the channel?s southern boundary. Interaction ...

Abstract: he assumption that local baroclinic instability dominates eddy?mean flow interactions is tested on a global scale using a dynamically consistent eddy-permitting state estimate. Interactions are divided into local and ...

Abstract: he amplitude, origin, and direction of striations in the subtropical gyre are investigated using simulated and analytical multidimensional spectra. Striations, defined as banded structures in the low-frequency motions, ...

Abstract: The evolution of an isolated, axially symmetric vortex is calculated with a quasi-geostrophic, adiabatic, hydrostatic. ?-plane, two vertical mode model. The circumstances of greatest interest are those of weak friction and ...
