Secondary generation of gravity waves associated with the breaking of mountain waves

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 to charact...

Description
Summary: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 to characterize the breaking and generation of gravity waves in the stratosphere. The mean flow is initialized by CIRA86 at 40degreeN in February. A bell-shaped mountain with 30-km half-width and 1.5-km height is located in the bottom of the modeled domain.
