Gravity Waves in the Atmosphere: Instability, Saturation, and Transport.

reportActive / Technical Report | Accession Number: ADA303638 | Open PDF

Abstract:

The excitation, propagation, breakdown, absorption of gravity waves in the atmosphere is fundamentally important to the momentum balance, transport of heat and constituents, and general circulation. This report describes the results of several studies pertaining to excitation of inertia gravity waves in midlatitude baroclinic systems, effects of the quasi-biennial oscillation on the inertia gravity and Kelvin wave spectrum a the equator, the role of gravity wave drag in the extratropical QBO, destabilization of large-scale tropical waves by deep moist convection, and a general theory of equatorial inertial instability on a zonally nonuniform, nonparallel flow.
