Abstract

Effects of basic-state wind on the secondary waves generated by the breaking of the gravity waves in the mesosphere are investigated based on two-dimensional numerical simulations under three (quiescent, uniform, and sheared) idealized basic-wind profiles. The source of the primary gravity waves is given by a quasi-monochromatic wave oscillator with a Gaussian envelope centered at the upper troposphere. Spectral characteristics of the secondary waves in the mesosphere differ significantly in each simulation, although the spectral shapes of the nonlinear forcing due to breaking of the primary waves are similar. The differences are due mainly to the propagation condition of the secondary waves, which is determined by the basic-state wind for a given stability, during their passage downward from the nonlinear forcing located in the upper mesosphere.
