Conference paper


A model is proposed for the breakdown of internal gravity waves in the middle and upper atmosphere. It follows earlier models in using an eddy diffusivity which is just sufficient to limit the overturning of isentropic surfaces. However, it extends previous models in allowing indpendent calculation of eddy viscosity and conductivity coefficients. Results are presented for the interaction of a single wave mode with a critical level.
