GMME: Meso-scale modelling group
| Head of division : Dr. Christine Lac |
The Mesoscale Meteorology Research Group (GMME : Groupe de Météorologie de Moyenne Echelle) is one of the 4 divisions of CNRM (UMR 3589, CNRS and Météo-France).
It leads basic research on mesoscale and microscale processes of the atmosphere and their interactions with surfaces. Research interest is disverse with an overarching goal to advance our understanding, modelling and prediction of high-impact weather, including clouds and fogs, urban climate, convection, heavy precipitation and hydrological impacts.
To increase our understanding of mesoscale and microscale processes, the Mesoscale Meteorology division develops detailed modelling (e.g. Large Eddy Simulation) and designs and participates to field campaigns. CAPITOUL, AMMA or HyMeX SOP1 & SOP2 are examples of field campaigns initiated and conducted by scientists of GMME.
Research aims at improving the representation of the mesoscale processes within the Météo-France numerical weather prediction and climate models through development and improvement of physical parametrizations, mesoscale data assimilation, ensemble forecasting methods, downscaled or impact modeling.
