Inertial Taylor Columns and Jupiter's Great Red Spot
Publisher: American Meteorological Society
Abstract: A homogeneous fluid is bounded above and below by horizontal plane surfaces in rapid rotation about a vertical axis. An obstacle is attached to one of the surfaces, and at large distances from the obstacle the relative ...
The Runaway Greenhouse: A History of Water on Venus
Publisher: American Meteorological Society
Abstract: Radiative-convective equilibrium models of planetary atmospheres are discussed for the case when the infrared opacity is due to a vapor in equilibrium with its liquid or solid phase. For a grey gas, or for a gas which ...
Boussinesq and Anelastic Approximations Revisited: Potential Energy Release during Thermobaric Instability
Publisher: American Meteorological Society
Abstract: Expressions are derived for the potential energy of a fluid whose density depends on three variables: temperature, pressure, and salinity. The thermal expansion coefficient is a function of depth, and the application is ...
Testing the Hypothesis that the MJO is a Mixed Rossby–Gravity Wave Packet
Publisher: American Meteorological Society
Abstract: The Madden?Julian oscillation (MJO), also known as the intraseasonal oscillation (ISO), is a planetary-scale mode of variation in the tropical Indian and western Pacific Oceans. Basic questions about the MJO are why it ...
On the Minimum Potential Energy State and the Eddy Size–Constrained APE Density
Publisher: American Meteorological Society
Abstract: xactly solving the absolute minimum potential energy state (Lorenz reference state) is a difficult problem because of the nonlinear nature of the equation of state of seawater. This problem has been solved recently but the ...
Triggered Convection, Gravity Waves, and the MJO: A Shallow-Water Model
Publisher: American Meteorological Society
Abstract: he Madden?Julian oscillation (MJO) is the dominant mode of intraseasonal variability in the tropics. Despite its primary importance, a generally accepted theory that accounts for fundamental features of the MJO, including ...
Potential Vorticity and Layer Thickness Variations in the Flow around Jupiter's Great Red Spot and White Oval BC
Publisher: American Meteorological Society
Abstract: Layer thickness variations in Jupiter's atmosphere are investigated by treating potential vorticity as a conserved tracer. Starting with the horizontal velocity field measured from Voyager images, fluid trajectories around ...
A Normal-Mode Approach to Jovian Atmospheric Dynamics
Publisher: American Meteorological Society
Abstract: We propose a nonlinear, quasi-geostrophic, baroclinic model of Jovian atmospheric dynamics, in which vertical variations of velocity are represented by a truncated sum over a complete set of orthogonal functions obtained ...
Jupiter's Great Red Spot as a Shallow Water System
Publisher: American Meteorological Society
Abstract: Most current models of Jupiter's Great Red Spot (GRS) are cast in terms of a two-layer model, where a thin upper weather layer, which contains the vortex, overlies a much deeper layer, which is meant to represent the ...
High-Frequency Orographically Forced Variability in a Single-Layer Model of the Martian Atmosphere
Publisher: American Meteorological Society
Abstract: A shallow water model with realistic topography and idealized zonal wind forcing is used to investigate orographically forced modes in the Martian atmosphere. Locally, the model produces barotropic modes with periods within ...
