RCM2009 3rd day †

9:00 Bill Gutowski (Iowa state U)

  • dynamic grid stretching
  • EULAG (Eulerian/semi-Lagrangian Fluid Soler)
  • Coupled with CAM3
  • Maximum vertical velocity: EULAG > FV > ESP (eulorian spectral)

9:30 Erik van Meijgaard (KNMI, netherlands)

  • HTESSEL land surface model (6 tiles) (included in ERA40)
    • deeper soil layer
    • non-linear water stress function
    • reduced percolation rate
  • From TESSEL to HTESSEL:
    • C&H to VG.
    • variable soil depth
    • groudwater
  • results compared with SEBAL (derived from MODIS, Bastiaansse 1998, J.Hydrol)

9:50 Anna Rutgersson (Uppsala U, Swe)

  • wave model, with Rossby Centre regional climate model (RCA)
    • swell (faster), wind sea (slower)
  • decaying waves (swell):
    • less friction, less mixing
    • wind gradient affected
  • coupling
    • one way (A to W)
    • two way (A to W and W to A)
    • three way (two way + swell impact)
  • impact
    • on wind histogram
    • on precipitation(?)
    • on surface temperature: cooling on north sea

10:30 Andrew Ferrone (U. Louvain, Belgium)

  • CLM regional model (COSMO)
  • airplain contrails parameterization

10:50 Ruby Leung (PNL)

  • Aerosols impact
  • two moment bulk microphysical model (BM; mass & number concentrations)
  • spectral bin microphysics (SBM); seven types of hydrometeors, 33 mass bins

11:15 Hlger Gottel (MPI)

  • REMO, non-hydrostatic, 5km(?)
  • 20% more computation
  • better convection (?)

11:35 Andreas Will (Brandenburg U. Tech.)

  • COSMO-CLM, aiming 7km 12:00 Andreas Weigel (Meteo Swiss)
  • Multimodel weighting
  • Ranked Probability Skill Score
  • degree of "Ignorance"= -log2(P)
  • larger ignorance difference, more gain by optimal weighting.
  • equal weighting is "safe."
  • optimal weighting may help reducing ensemble members
  • when applying to the climate change simulations, the current climate skill maybe becomes wrong weights. 12:30 Barry Lynn (Weather it is, Israel)
  • Hurricane

14:20 Mirta Patarcic

  • ECMWF seasonal forecast (9 ensemble) DS
  • Brier score
  • No improvement by RegCM3! (cold bias over whole domain)

14:40 S. Himesh (India)

  • sensitivity of various domains, various grid sizes 15:00 Erik Kjellstrom, Rossby Center
  • Ensemble regional climate simulations (RCA3)
  • Choice of GCM dominates source of uncertainty for seasonal means (Deque 2007)

15:20 Klaus Keuler (BTU, Germany)

  • 3 ensemble streams of same emmision scenario, same GCM.
  • 18km, 140yr, Europe (250x250), 3 streams
  • What is added value?

Poster session

  • Andreas Weigel
  • Quebecの子とNanjingの子にLateral boundaryをやめたら？といったらきょとんとされた。

17:00 Jan Polcher

  • AMMA-Reanalysis by ECMWF (2006 May-Sep)

17:30 Thomas Werner (NCAR)

  • Regional reanalysis (CFDDA)
  • continuous assimilation
  • frontier application wind energy

17:50 Thomas Klein

  • Hindcasting Europe's climate- A user side
  • EURRA

18:10 Frank Kaspar

  • Climate Monitoring Satellite Application Facility
