SIMULATIONS NUMERIQUES D'EPISODES DE PRECIPITATIONS INTENSES DOCUMENTES LORS DE LA CAMPAGNE DE MESURES MAP (MESOSCALE ALPINE PROGRAMME)

Abstract : Heavy rainfalls frequently occur on the southern side of the Alps,
resulting in casualties and millions of US dollars worth of damage.
Improving the understanding and forecasting of these events is one of
the central objectives of current operational meteorology.
In 1999, the Mesoscale Alpine Programme (MAP) provided detailed
documentation on several major rain events.
In this study, some of these events are simulated using the French
non-hydrostatic model, Meso-NH.
We first focus on the sensitivity of the forecasting of a strong
convective event to the microphysical scheme used in the model, and to
the initial conditions.
The study is then broadened to two other MAP events.
It appears clearly that different flow regimes generate
different microphysical behaviour of the clouds.
