Abstract: The one-dimensional propagation of a spectrum of gravity waves through a realistic middle atmosphere is investigated, separating as far as possible the propagation-invariant aspects from the more empirical wave-breaking ...

Abstract: This paper describes a new computationally efficient, ultrasimple nonorographic spectral gravity wave parameterization model. Its predictions compare favorably, though not perfectly, with a model of gravity wave propagation ...

Abstract: The impact of a parameterized spectrum of gravity waves on the simulation of the stratosphere in the Met Office Unified Model (UM) is investigated. In the extratropical mesosphere, the gravity wave forcing acts against the ...
