1. INSTYTUT METEOROLOGII I GOSPODARKI WODNEJ INSTITUTE OF METEOROLOGY AND WATER MANAGEMENT TITLE: IMGW in COSMO AUTHOR: Michał Ziemiański DATA: 18. 09. 2008

2. INSTITUTE OF METEOROLOGY AND WATER MANAGEMENT IMGW strategy for NWP: increase the engagement of IMGW in the area of the NWP development, strengthen the cooperation between IMGW and academia (esp. Warsaw University of Technology and University of Warsaw), build international cooperation with important NWP centres (NCAR, ECMWF – membership probably from 2010), increase computational capabilities based on own Linux-cluster environment and cooperation with academic computational centres (Poznań, Gdańsk), increase and concentrate resources on well defined areas of model development (esp. dynamics, assimilation).

3. INSTITUTE OF METEOROLOGY AND WATER MANAGEMENT Achievements over the last COSMO year: 1dVar: incorporation of nudging mode, implementation of AMSU-A, B data nudging, UTCS: tests of modifications in the COSMO-model deep convection Tiedtke’s scheme, VERSUS: porting of Common Verification Suite package, preparation of the VERSUS package for delivery, KENDA: participation in implementation of an ensemble data assimilation framework, modification of model code, INTERP: development of hydrological products based on COSMO model, “fuzzy” verification of very high resolution model.

4. INSTITUTE OF METEOROLOGY AND WATER MANAGEMENT Status of the NWP system: 14-km grid resolution, COSMO reference model version, no assimilation cycle, boundary and initial conditions from GME, hardware: SGI 3800.

5. INSTITUTE OF METEOROLOGY AND WATER MANAGEMENT Future development of the NWP system: moving to Linux cluster environment (2008/2009), operational implementation of the 7-km resolution in 2009, semi-operational implementation of 2.8 km resolution for selected, small-area sub-domains (2009/2010), implementation of the assimilation cycle (2009/2010), implementation of operational 2.8 km resolution (2012/2013, depending mainly on hardware availability).

6. INSTITUTE OF METEOROLOGY AND WATER MANAGEMENT Future contributions to COSMO: new COSMO-oriented team (about 2-3 persons) dedicated to implementation of the EULAG, finite volume based, dynamical core to the COSMO model, strong involvement in 1-d var assimilation of satellite data, involvement in programs/projects/tasks of general interest to the consortium (data assimilation, convection parameterization, verification, etc).
