TLDR
The Meso-NH Atmospheric Simulation Engine as mentioned in this paper is a tool for small and meso-scale atmospheric processes, which is based on the Lipps and Hemler form of the anelastic system.Abstract:
The Meso-NH Atmospheric Simulation Sys- tem is a joint eAort of the Centre National de Recher- ches Meteorologiques and Laboratoire d'Aerologie. 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 com- putation and accumulation of various terms of the budget of several quantities. It allows for the transport and diAusion 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 ini- tialization methods is also given. A more precise description of these aspects will be provided in a further paper.read more

TL;DR: In this paper, the authors have implemented ForeFire, a surface model initially realized to simulate forest fire, by adapting it to reproduce the dynamic of a lava flow, showing that all flows (SO2, heat, vapor, CO2, CO) are triggered depending on its dynamic.

Fully multidimensional flux-corrected transport algorithms for fluids
TL;DR: In this paper, the critical flux limiting stage is implemented in multidimensions without resort to time splitting, which allows the use of flux-corrected transport (FCT) techniques in multi-dimensional fluid problems for which time splitting would produce unacceptable numerical results.

TL;DR: In this article, a parameterization of land surface processes to be included in mesoscale and large-scale meteorological models is presented, where the number of parameters has been reduced as much as possible, while attempting to preserve the representation of the physics which controls the energy and water budgets.

A Simple Boundary Condition for Unbounded Hyperbolic Flows
TL;DR: In this article, a Sommerfeld radiation condition (2.2) was proposed for problems requiring a prescribed open boundary, and two severe tests were used to demonstrate the applicability of the open boundary condition: collapsing bubble, a dynamic event which excites many different internal gravity waves.

On the distribution and continuity of water substance in atmospheric circulations
TL;DR: In this paper, the conservation and distribution of water substance in atmospheric circulations are considered within a frame of continuity principles, model air flows, and models of microphysical processes, where the simplest considerations of precipitation involve its vertical distribution in an updraft column, where condensate appears immediately as precipitation with uniform terminal fallspeed.
