DESCRIPTION

Verification COSMO WG3/5 workshop, Langen, 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

Verification A first attempt to WP Preliminary results of one test case Matteo Buzzi, Pirmin Kaufmann, Dominique Ruffieux, Francis Schubiger MeteoSwiss Verification COSMO WG3/5 workshop, Langen, Compared model runs for forecast of 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 Verification COSMO WG3/5 workshop,

workshop, Langen, Summary (Exp002 as compared to Exp001) PBL at Payerne: especially during the night and in the first part of the forecast reduced dry bias (less dry) reduced warm bias (colder) SYNOP: increased negative bias in T2m and Td2m increased regions with low clouds over land Diffusion coefficients, TKE and T(ground till k=ke-2) at Payerne Lower values in Exp002 (as defined in set-up) in temperature: extremely large vertical gradients and erratic temporal behaviour (not understood) ANETZ: Larger diurnal amplitude in T2m (colder during night) erratic behaviour in Td2m at some locations in Exp002 and LM
