Deep convection events which have the potential to induce heavy precipitation are to be investigated within the "wet component" of MAP. The Alpine Region is a preferred region for the formation of thunderstorms and severe precipitation (including hail).
The Severe Thunderstorm Experiment (SETEX) was conducted as a pilot campaign for MAP during June and July 1994 in the north Alpine foreland in order to monitor the development and progression of thunderstorms and associated squall-lines. One of the sample cases addressed to the life cycle of a mesoscale convective system (MCS) which was documented during the second half of 4 July 1994. Radar data are available from the Swiss and German networks and the research radar of the DLR.
Modelling studies will be performed with the DM/EM, an operational numerical weather prediction model developed and run by the German Weather Service.
In this regional numerical weather prediction model the important microphysical processes for the formation of precipitation are parameterized. With case studies it is investigated to what extent it is possible to forecast heavy precipitation events in the Alpine Region.
Some background material for this modelling studies which are underway under the auspices of the MAP working group on numerical experimentation is presented on the poster.
