| Zusammenfassung |
| The Meso-NH Atmospheric Simulation System is
a joint effort of the Centre National de Recherches Météorologiques and
Laboratoire d'Aérologie. It comprises several elements; a numerical model able
to simulate the atmospheric motions, ranging from the large meso-alpha scale
down to the micro-scale, with a comprehensive physical package, a flexible file
manager, an ensemble of facilities to prepare initial states, either idealized
or interpolated from meteorological analyses or forecasts, a flexible
post-processing and graphical facility to visualize the results, and an ensemble
of interactive procedures to control these functions. Some of the distinctive
features of this ensemble are the following: the model is currently based on the
Lipps and Hemler form of the anelastic system, but may evolve towards a more
accurate form of the equations system. In the future, it will allow for
simultaneous simulation of several scales of motion, by the so-called
"interactive grid-nesting technique". It allows for the in-line
computation and accumulation of various terms of the budget of several
quantities. It allows for the transport and diffusion of passive scalars, to be
coupled with a chemical module. It uses the relatively new Fortran 90 compiler.
It is tailored to be easily implemented on any UNIX machine. Meso-NH is designed
as a research tool for small and meso-scale atmospheric processes. It is freely
accessible to the research community, and we have tried to make it as
"user-friendly" as possible, and as general as possible, although
these two goals sometimes appear contradictory. The present paper presents a
general description of the adiabatic formulation and some of the basic
validation simulations. A list of the currently available physical
parametrizations and initialization methods is also given. A more precise
description of these aspects will be provided in a further paper. |
