  1. A first attempt to WP 5.6.2Preliminary results of one test case Matteo Buzzi, Pirmin Kaufmann, Dominique Ruffieux, Francis Schubiger MeteoSwiss

  2. Compared model runs for forecast of 12.12.04 • Model versions: • Exp001 • Exp002 • operational aLMo (without TKE) and LM • aLMo-TKE:TKE version opr at DWD + “last changes” • SYNOP • total cloudiness, T(k=ke, 2m), qv (k=ke), Td2m • Model diffusion coefficients and TKE in the PBL at Payerne • Measurements from Payerne • Sounding • T2m, T5cm • ANETZ • T2m, Td2m, (T-Td)2m, 10m-wind, total cloudiness francis.schubiger@meteoswiss.ch COSMO WG3/5 workshop, Langen, 09.03.2005

  3. Shortcomings for conditional verification • Only one test case with: • over the Swiss Middleland: low clouds (stratus) but not in the model forecast • wind at 10 m and in the PBL very weak • SYNOP verification not yet available as conditional verification • no precipitation francis.schubiger@meteoswiss.ch COSMO WG3/5 workshop, Langen, 09.03.2005
