RISSimulation of Inertia–Gravity Waves in a Poleward-Breaking Rossby Wave
Publisher: American Meteorological Society
Abstract: Poleward-breaking Rossby waves often induce an upper-level jet streak over northern Europe. Dominant inertia?gravity wave packets are observed downstream of this jet. The physical processes of their generation and propagation, ...
Parameterization of Strong Stratospheric Inertia–Gravity Waves Forced by Poleward-Breaking Rossby Waves
Publisher: American Meteorological Society
Abstract: The link between poleward-breaking Rossby waves and stratospheric inertia?gravity waves is examined. With a visual inspection of Ertel?s potential vorticity maps based on ECMWF analyses it was found that Rossby wave?breaking ...
On the Quantification of Imbalance and Inertia–Gravity Waves Generated in Numerical Simulations of Moist Baroclinic Waves Using the WRF Model
Publisher: American Meteorological Society
Abstract: AbstractQuantification of inertia?gravity waves (IGWs) generated by upper-level jet?surface front systems and their parameterization in global models of the atmosphere relies on suitable methods to estimate the strength ...
Structure, Energy, and Parameterization of Inertia–Gravity Waves in Dry and Moist Simulations of a Baroclinic Wave Life Cycle
Publisher: American Meteorological Society
Abstract: he impact of moisture on inertia?gravity wave generation is assessed for an idealized unstable baroclinic wave using the Weather Research and Forecasting Model (WRF) in a channel on the f plane. The evolution of these waves ...

Coupling of Stratospheric Warmings with Mesospheric Coolings in Observations and Simulations
Publisher: American Meteorological Society
Abstract: AbstractThe vertical coupling between the stratosphere and the mesosphere is diagnosed from polar cap temperatures averaged over 60°?90°N with a new method: the joint occurrence of a warm stratosphere at 10 hPa and a cold ...
