1 The Elbe 2002 Case Daniela Jacob, Stefan Hagemann, Sven Kotlarski Philip Lorenz, Susanne Pfeifer, Ralf Podzun Max-Planck-Institut for Meteorology, Hamburg, Germany

2 Daniela Jacob, WMO/ ICMW, Hamburg, July 2004 heavy precipitation  flooding, land slides….. heat waves  drought, fires….. local to regional extension with high impact to society Will Europe face more extremes?

3 Daniela Jacob, WMO/ ICMW, Hamburg, July 2004 Dresden, August 2002 Century flood of Rhine and Moselle in December 1993 Century flood of Rhine and Moselle in December 1993 Century flood again of Rhine and Moselle in January 1995 Century flood again of Rhine and Moselle in January 1995 Century flood of the Oder in July 1997 Century flood of the Oder in July 1997 Flood of the Danube and Lake Constance in May 1999 Flood of the Danube and Lake Constance in May 1999 Extensive and long-lasting floods in western Europe, in particular south England and Wales, in the autumn of 2000 Extensive and long-lasting floods in western Europe, in particular south England and Wales, in the autumn of 2000 Flood of the Vistula in July 2001 Flood of the Vistula in July 2001 Flood of the Danube in August 2002 Flood of the Danube in August 2002 Century flood of the Elbe in August 2002 Century flood of the Elbe in August 2002 Extreme precipitation and dreadful floods in southern France in September 2002 Extreme precipitation and dreadful floods in southern France in September 2002 Severe flooding in parts along German rivers in January 2003 Severe flooding in parts along German rivers in January 2003 source: Spiegel Nr ; Quarterly report of the DWD, special topic July 2003

20 Daniela Jacob, WMO/ ICMW, Hamburg, July 2004  Is it possible to simulate such extreme precipitation events as sub grid scale processes in regional climate models (this is a prerequisite for climate change studies)?  Which role plays the microphysics?  Microphysics versus realistic simulation of the synoptic scale? Conclusions / Questions
