On the Man-Machine Supervision of Precipitation Ensemble Forecast

The production of localized and accurate meteorological forecast is of primary importance for the prediction of natural hazards, the management of civil engineering project, the direction of aeronautic services or in the organization of outdoor events. The highly varying landscape over Switzerland together with the inherent complex dynamics of the atmosphere makes that task an extremely difficult. goal in general, and especially at the scale of a few hours and of a few kilometers squared. The considerable development of the numerical models have led to the daily production of several detailed simulations delivering approximations for the future three-dimensional state of the troposphere over the country.
