Bad weather in Potsdam in the mid of the 21th century? Matze/Carsten March 2015
Project: “Concept for Adaptation to Climate Change in the State Capital of Potsdam” City applies, BMU pays, we do it together with RD4 (Fritz) and 2 Potsdam based engineering offices (LUP, RegioFutur) Suggestions for adaptation measures Urban climate change impacts Climate Change projections for Potsdam
Projections: Statistical (i.p. resampling), e.g. STARS Dynamic (physical mechanisms), e.g. CORDEX contributers

Analysis of CORDEX results. Example: annual mean of daily max. temperature 12 GCM/RCM combinations
Annual precipitation Observed annual precipitation Relative frequency for projected change [% comp. to 1970-2000] for 2045 (blue) and 2085 (red). Dashed lines: single model results for 2045 Dotted lines: single model results for 2085
Total runoff per year Relative frequency for projected change [% comp. to 1970-2000] for 2045 (blue) and 2085 (red). Dashed lines: single model results for 2045 Dotted lines: single model results for 2085
Heavy rain days (Prc > 16mm) per year Observed heavy rain days Relative frequency for projected change [% comp. to 1970-2000] for 2045 (blue) and 2085 (red). Dashed lines: single model results for 2045 Dotted lines: single model results for 2085 advective + convective rain: convective rain:
Hot days (Tmax > 30°C) per year Observed hot days Relative frequency for projected change [% comp. to 1970-2000] for 2045 (blue) and 2085 (red). Dashed lines: single model results for 2045 Dotted lines: single model results for 2085
