ALADIN HIRLAMmesoscale co-operation

2003=>• HIRLAM for co-operation with AROME Project • ALADIN interest on HIRLAM DA achievements• Common interest in EPS on different scales “Future developments requires more resources that

could be achieved by collaboration”

2004=> Contacts at management levels - ALADIN coordinator at HAC - LACE Steering Committee open for HIRLAM Co-operation on Council levels

ALADIN HIRLAMscientific and code cooperation

• AAA training for HIRLAM MG on March 2004• 14th ALADIN WS, June 2004 Innsbruck• Decision about interfacing on the equation and code

levels – (TCWSDPI, Nov 2004, Prague)• ALADIN-HIRLAM reference code a ECMWF (2005)• HMG-CSSI coordination meeting, June 2005 Bratislava

– code collaboration and maintenance, phasing– Scientific strategy and working plans:

dynamics and coupling, physics, surface, DA, predictability, verification

• ALADIN-HIRLAM Sc. plan expected (October 2005)

7th COSMO meeting Zurich
