Encyclopedia of Atmospheric Sciences: Second Edition | Published : 2015

Abstract

Atmospheric convection is an important source of gravity waves. The gravity waves are caused by vertical displacements of stable air associated with convective elements, along with the diabatic heating and cooling within moist convection. Gravity waves can be generated by shallow or deep convection and the waves normally propagate vertically and horizontally away from their source. While in the troposphere, convective gravity waves can affect the stability and modify further convective development. In the troposphere, stratosphere, and mesosphere the dissipation of convective gravity waves exerts a tendency on the mean flow and thereby contributes to the momentum budget of those layers.
