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 ...
Early-Time Solution for a Radial Hydraulic Fracture
Publisher: American Society of Civil Engineers
Abstract: The small-time asymptotic solution for a penny-shaped fluid-driven fracture is obtained semianalytically. Scaling considerations indicate that the portion of the fracture that is filled with fluid increases with time ...
Mixing Structure of High-Frequency Internal Waves in the Upper EasternEquatorial Pacific
Publisher: American Meteorological Society
Abstract: A thermistor chain towed from 140° to 110°W along the equator revealed the presence of high-frequency internal waves in the upper 125 m having zonal wavelengths of 150?250 m. Turbulence dissipation rates, ε, observed from ...
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 ...
Slider-Cranks as Compatibility Linkages for Parametrizing Center-Point Curves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In synthesizing a planar 4R linkage that can achieve four positions, the fixed pivots are constrained to lie on a center-point curve. It is widely known that the curve can be parametrized ...
