**RCM2009 3rd day [#z2426575]
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
