Numerical simulation of tides, Rossby and Kelvin waves with the COMMA-LIM model

Kai-Uwe Frohlich; A. Pogoreltsev; Ch. Jacobi

Abstract A 48-layer version of the COMMA-LIM (Cologne Model of the Middle Atmosphere at Leipzig Institute for Meteorology) three-dimensional global mechanistic model of the Earths atmosphere from 0 km to 135 km with logarithmic pressure height coordinates was developed. The model is capable of reproducing the global structures and propagation of different planetary waves in the middle atmosphere. The contribution of gravity waves, tides, Rossby and Kelvin waves on the zonally averaged momentum budget of the mesosphere / lower thermosphere region is investigated.
