Abstract

AbstractA linear theory of internal gravity waves (IGWs) is applied to consider the IGW‐induced vertical fluxes of kinetic energy, pressure and squared density (or buoyancy) in non‐turbulent stably stratified fluid characterized by the Brunt–Väisälä frequency, N. These fluxes are required in modelling distant links and non‐local transports in the atmosphere. Investigations of the vertical flux of kinetic energy have shown that this flux, caused by the wave component performing the most efficient vertical transport, is proportional to N3. As far as the authors know, the flux of the squared density fluctuations was not systematically investigated. It is shown to be proportional to N5. Copyright © 2002 Royal Meteorological Society.
