| In order to study the sensitivity of snow
cover to changes in meteorological variables at a regional scale, a numerical
snow model and an analysis system of the meteorological conditions adapted to
relief were used. This approach has been successfully tested by comparing
simulated and measured snow depth at 37 sites in the French Alps during a ten
year data period. Then, the sensitivity of the snow cover to a variation in
climatic conditions was tested by two different methods, which led to very
similar results. To assess the impact of a particular "doubled CO2"
scenario, coherent perturbations were introduced in the input data of the snow
model. It was found that although the impact would be very pronounced, it would
also be extremely differentiated, dependent on the internal state of the snow
cover. The most sensitive areas are the elevations below 2400 m, especially in
the southern part of the French Alps. |
