A satellite triangle for gravity waves

Gravity waves are the one major prediction of Einstein's generalrelativity theory that has not been directly detected or demonstrated by experimental equipment. These waves-- gravity's analog to radio--are cyclic disturbances of gravitational forces generated by cosmic or astrophysical processes. Like radio waves, they propagate themselves through space.

The rather ambitious experimental effort now under way tofind gravi...

Gravity waves appearing in a high-resolution GCM simulation
Journal of the Atmospheric Sciences ; ABSTRACT Global characteristics of gravity waves in the lower stratosphere are examined using a GCM with high resolution in both the horizontal (T106, corresponding to about 120 km) and the vertical (-600 m). The bottom boundary condition of the model is that of an aquaplanet with perpetual
Intimations of gravity waves.
Science News ; Intimations of gravity waves Gravity waves are -- theoretically -- cyclic disturbances ofgravitational forces that propagate themselves through space. Generated by astrophysical processes like supernovas or binary stars, they are gravity's analog to radio waves. Physicists are eagerly awaiting a
Convectively generated gravity waves and their effect on the cloud environment
Journal of the Atmospheric Sciences ; ABSTRACT This study uses a two-dimensional cloud-resolving model to examine how convectively generated gravity waves modify the environment of an isolated convective cloud. The model is initialized with an idealized sounding, and the cloud is initiated by adding a locally buoyant perturbation. The

Vertically propagating gravity waves
Bulletin of the American Meteorological Society ; Vertically propagating internal gravity waves play a major role in dynamically linking the lower and middle atmospheres. Among various gravity wave sources, cumulus convection has received much attention as a possible source of nonstationary gravity waves, especially in the Tropics. However,
Generation mechanisms of convectively forced internal gravity waves and their propagation to the stratosphere
Journal of the Atmospheric Sciences ; ABSTRACT Characteristics of gravity waves induced by mesoscale convective storms and the gravity wave sources are investigated using a two-dimensional cloud-resolving numerical model. In a nonlinear moist (control) simulation, the convective system reaches a quasi-steady state after 4 h in which
Secondary generation of gravity waves associated with the breaking of mountain waves
Journal of the Atmospheric Sciences ; ABSTRACT The generation of small-scale gravity waves associated with the breaking of mountain waves in the stratosphere has been simulated within a fully compressible, nonhydrostatic, two-dimensional numerical model. The model includes the mesosphere and offers sufficiently high spatial resolution
Sensitivity of Mesoscale Gravity Waves to the Baroclinicity of Jet-Front Systems
Monthly Weather Review ; ABSTRACT This study investigates the sensitivity of mesoscale gravity waves to the baroclinicity of the background jet-front systems by simulating different life cycles of baroclinic waves with a high-resolution mesoscale model. Four simulations are made starting from two-dimensional baroclinic
Gravity waves elusive for scientists trying to study them.(Knight Ridder Newspapers)
Knight Ridder/Tribune News Service ; WASHINGTON _ Scientists this fall began trying to measure one of nature's strangest phenomena _ gravity waves. These are ripples in the fabric of space itself _ like wind-whipped ruffles in the walls of a tent _ that are caused by massive star explosions, collisions between galaxies and other such
