Estimation statistique et réanalyse des précipitations en montagne
Utilisation d'ébauches par types de temps et assimilation de données d'enneigement
Application aux grands massifs montagneux français

Abstract : The estimation of snow storage and precipitation, essential for managing hydroelectric reservoirs of EDF, still remains subject to considerable uncertainties. EDF-DTG currently seeks to develop some tools for robust interpolations, able to provide a reliable estimate of precipitation and snow water equivalent at any point in mountainous areas. The developed tools are essentially based on the ground sensor network of DTG, which measures precipitations, snow depth and water equivalent over French mountains.
In the long term, these tools should make it possible to progress towards a better spatial vision of the daily or “event” precipitation, as well as of the snow cover on the ground, based on measurements taken all over the basins requiring an operational hydrological forecast.
