✦ Synopsis
Simultaneously to improvements of computer performance and of availability of memory not only the resolution of meteorological models of atmospheric currents has been re®ned but also the accuracy of the necessary physical approximations has been improved more and more. Now full elastic models are developed which describe also sound waves, although sound processes are not supposed to be relevant for atmospheric ¯ow phenomena. But the full set of the elastic Navier±Stokes equations has a quite simple structure in comparison to sound proved systems like anelastically'' approximated models, so that the corresponding numerical models can be implemented on parallel computer systems without too much eorts. This has been considered by the redesign of the Karlsruhe Atmospheric Mesoscale Model'' (KAMM) for parallel processing.The new full elastic version of this model is written in FORTRAN-90. The necessary communication operations are gathered into few functions of a communication library, which is designed for dierent computer architectures, for massive parallel systems, for parallel vector computers requiring long vectors, but also for mono processors.
