Equatorially Bounded Zonally Propagating Linear Waves on a Generalized β Plane
Publisher: American Meteorological Society
Abstract: Meridionally confined zonally propagating wave solutions to the linear hydrostatic Boussinesq equations on a generalized equatorial ? plane that includes the ?nontraditional? Coriolis force terms associated with the poleward ...
Secondary Instabilities in Breaking Inertia–Gravity Waves
Publisher: American Meteorological Society
Abstract: he three-dimensionalization of turbulence in the breaking of nearly vertically propagating inertia?gravity waves is investigated numerically using singular vector analysis applied to the Boussinesq equations linearized ...
Symmetric Stability of Compressible Zonal Flows on a Generalized Equatorial β Plane
Publisher: American Meteorological Society
Abstract: Sufficient conditions are derived for the linear stability with respect to zonally symmetric perturbations of a steady zonal solution to the nonhydrostatic compressible Euler equations on an equatorial ? plane, including ...
Validation of Large-Eddy Simulation Methods for Gravity Wave Breaking
Publisher: American Meteorological Society
Abstract: To reduce the computational costs of numerical studies of gravity wave breaking in the atmosphere, the grid resolution has to be reduced as much as possible. Insufficient resolution of small-scale turbulence demands a ...
Equatorial Zonal Jet Formation through the Barotropic Instability of Low-Frequency Mixed Rossby–Gravity Waves, Equilibration by Inertial Instability, and Transition to Superrotation
Publisher: American Meteorological Society
Abstract: Depth-dependent barotropic instability of short mixed Rossby?gravity (MRG) waves is proposed as a mechanism for the formation of equatorial zonal jets. High-resolution primitive equation simulations show that a single MRG ...
