Hysteresis and the Transition between Axisymmetric Flow and Wave Flow in the Baroclinic Annulus
Publisher: American Meteorological Society
Abstract: A numerical model is used to determine the transitions between axisymmetric flow and wave flow in the rotating, differentially heated annulus experiments of Fein for both rigid lid and free surface cases. For most of the ...
Near-Symmetric Instability for General Prandtl Number
Publisher: American Meteorological Society
Abstract: An analysis of the stability of a simple, baroclinic flow to perturbations whose horizontal wave vector lies in and near the vertical plane containing the density gradient has been performed. The Ekman number (E) and ...
A Linear Analysis of the Transition Curve for the Baroclinic Annulus
Publisher: American Meteorological Society
Abstract: A rotating cylindrical annulus of an incompressible fluid with horizontal density gradients is studied by the use of numerical models. Steady axisymmetric states are calculated using the full Navier-Stokes equations for a ...
Viscous Nongeostrophic Baroclinic Instability
Publisher: American Meteorological Society
Abstract: Calculations have been performed of the (linear) stability of a baroclinic flow to three-dimensional perturbations. Both the simple Eady basic state and the rotating Hadley cell of Antar and Fowlis are considered. The ...
Thermally Driven Flow in a Rotating Spherical Shell: Axisymmetric States
Publisher: American Meteorological Society
Abstract: Numerical models are utilized to study a spherical analogue of the rotating annulus experiments modeling atmospheric motion. Motivation for this work is partially provided by NASA's proposal to conduct such an experiment ...
A Numerical Simulation of Ice Crystal Growth from the Vapor Phase
Publisher: American Meteorological Society
Abstract: A detailed scheme for numerically integrating the diffusion equation for ice crystal growth is presented. The scheme is based on an extensive survey of observed crystal habits, densities and masses. Discrepancies between ...
The Effect of Satellite Observing System Changes on MERRA Water and Energy Fluxes
Publisher: American Meteorological Society
Abstract: ike all reanalysis efforts, the Modern Era Retrospective-Analysis for Research and Applications (MERRA) must contend with an inhomogeneous observing network. Here the effects of the two most obvious observing system epoch ...
