Comparison of high order algorithms in Aerosol and Aghora for compressible flows
This article summarizes the work done within the Colargol project during CEMRACS 2012. The aim of this project is to compare the implementations of high order finite element methods for compressible flows that have been developed at ONERA and at INRIA for about one year, within the Aghora and Aerosol libraries
Overview of the Meso-NH model version 5.4 and its applications
This paper presents the Meso-NH model version 5.4. Meso-NH is an atmospheric
non hydrostatic research model that is applied to a broad range of
resolutions, from synoptic to turbulent scales, and is designed for studies
of physics and chemistry. It is a limited-area model employing advanced
numerical techniques, including monotonic advection schemes for scalar
transport and fourth-order centered or odd-order WENO advection schemes for
momentum. The model includes state-of-the-art physics parameterization
schemes that are important to represent convective-scale phenomena and
turbulent eddies, as well as flows at larger scales. In addition, Meso-NH has
been expanded to provide capabilities for a range of Earth system prediction
applications such as chemistry and aerosols, electricity and lightning,
hydrology, wildland fires, volcanic eruptions, and cyclones with ocean
coupling. Here, we present the main innovations to the dynamics and physics
of the code since the pioneer paper of Lafore et al. (1998) and provide an
overview of recent applications and couplings
