“…In a very pioneering experiment in Europe, the Canadian MC2 model (Benoit et al, 1997) was run operationally during the whole MAP SOP at a resolution of 3 km over the entire Alpine domain. The main goal was to provide high-resolution forecasts in support of the field phase but also to gain early experience with a next-generation non-hydrostatic model.…”

“…The MAP SOP was the first major European field experiment for which quasi-operational forecasts were made with a highresolution (3 km) non-hydrostatic model working without parametrization for cumulus convection. The forecasts were obtained with the numerically innovative and efficient Canadian MC2 model (Benoit et al, 1997). At the same time, operational regional and global weather forecasts were available from several numerical weather prediction centres (Table I, models with an asterisk), providing an excellent opportunity to assess the performance of MC2 in comparison with lower-resolution hydrostatic models using parametrized convection.…”

ABSTRACT:The improvement of Quantitative Precipitation Forecasting (QPF) in mountainous regions was a major supporting objective of the Mesoscale Alpine Programme (MAP) project P1 devoted to the study of orographic precipitation. This paper reviews the main MAP-related achievements regarding QPF improvement and highlights the MAP impact on developing QPF research and planning future operational strategies. Recent results based on MAP case-studies, on data analysis and assimilation, on quantification of model uncertainties, and on model intercomparison and verification substantiate the progress made in recent years in improving model performance in relation to short-range, high-resolution forecasting in complex topography regions, well represented by the European Alps.

“…They are mainly (1) the anelastic model of Clark (1977), with its interactive grid-nesting capability; (2) the MM5 model (Dudhia, 1993); (3) the ARPS model (Xue et al, 1995); and (4) the Canadian MC2 model (Benoit et al, 1997). Most of these models have in common with Meso-NH some objectives of exibility, portability and maintainability.…”

The Meso-NH Atmospheric Simulation System. Part I: adiabatic formulation and control simulations

et al. 1998

Abstract. The Meso-NH Atmospheric Simulation System is a joint e ort of the Centre National de Recherches MeÂ teÂ orologiques and Laboratoire d'AeÂ rologie. 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¯exible ®le manager, an ensemble of facilities to prepare initial states, either idealized or interpolated from meteorological analyses or forecasts, a¯exible 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 di usion 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.

“…In fact, the Canadian MC2 limited area model (Benoit et al, 1997) simulations (not reported and available at http: //www.map.ethz.ch) indicate that the PV layers originating from the tropopause folding are dissipated above the relief before the measurements.…”

Analysis of water vapor LIDAR measurements during the MAP campaign: evidence of sub-structures of stratospheric intrusions

et al. 2005

View full text Add to dashboard Cite

Abstract. This paper presents two case studies of transport of dry air in the free troposphere measured by a ground based Raman LIDAR in the Northern-Italy, during the Mesoscale Alpine Programme (MAP). Two observations characterized by the presence of anomalously dry layers, below 6 km height, were analyzed using Lagrangian techniques. These events are related to upper-tropospheric, high Potential Vorticity (PV) streamers crossing the Alpine region. These are interpreted as small-scale features of stratospheric intrusions associated with the PV ridge during its phase of dissipation.One of the measurements also shows the presence of two distinct dehydrated structures associated with the same event. The water vapor concentration also suggests dilution processes of dry stratospheric air in the troposphere. Lagrangian simulations allowed to successfully reproduce the observed water vapor distribution and the air parcel histories confirmed the stratospheric origin of the dry layers.
