NH mesoscale suites

• HARMONIE cy31, 32 at 2.5km hor. resolution in
  DMI, FMI, SMHI, KNMI.
• Implementation at INM, Met.no, MetEireann
  ongoing.
• Several types of mesoscale models available at
  met.no down to 1km
• 3km NH HIRLAM mesoscale model at EMHI
• Monitoring of NRT suites on hirlam.org

6
Mesoscale modelling

• System aspects
• HARMONIE reference repository created (presently
  Cy32t2 code,scripts,namelist setup, monitoring
  evaluation tools).
• Aims full cycling system, build/job submission
  tools with HIRLAM look and feel.
• Physics
• Combined TKE/convection scheme EDMF integrated,
  implemented in ECMWF/AROME SCUM for extensive
  validation (Cabauw)
• Training week for all HIRLAM physics staff on
  HARMONIE, kickoff for experimentation and
  optimization
• Suitable physics required for mesoscale (AROME)
  but also grey zone (ALARO-1, HIRALD)
• Dynamics/Nesting/LBC
• Direct nesting in HIRLAM/ECMWF made possible.
• VFE discretization
• Possibility for transparent LBC in spectra model
  (Termonia) under discussion alternative (more
  frequent LBC coupling) under study.

Mesoscale modelling

• Data assimilation
• Starting from ALADIN 3D-VAR, 4D-VAR in a
  nutshell. Port experiences/methods for HIRLAM
  4D-VAR to this.
• Assimilation of hi-res obs radar
  reflectivities/winds GPS slant delays SEVIRI
  clear/cloudy radiances IASI binary cloud
  hi-res AMDAR, RS. Common obs operators defined
  for most of these.
• Surface
• Port snow/forest/sea/snow on ice/lake models to
  SURFEX
• Interface SURFEX to HIRALD
• Work on mesoscale surface DA starting this fall.

9
Synoptic model

• Assimilation and use of observations
• 4D-VAR preparation for implementation as default
  scheme
• Tuning of background error statistics
• Experimentation with large scale and lateral
  boundary constraints, new moisture variable,
• OpenMP parallellization efficiency improvements
• Future hybrid ensemble assimilation techniques
• Use of observations
• Coherent impact studies for N Atl, Arctic,
  convective parameters 34DV, synmeso
• Upgrade in RTTOV and AMSU treatment package
• New types of obs included AMSU-B, OSI-SAF
  SST/sea ice, scatterometer, MODIS winds, AMSU-A
  over land and sea ice.

10
Synoptic model

• Physics
• Surface scheme and orographically related
  parametrizations snow and forest, MSO/SSO,
  sloping surface radiation.
• Optimization/tuning to improve description of
  stable boundary layer (fog over sea, GABLS)
• Intercomparison STRACO - KF/RK convection
  schemes
• Surface
• Snow and forest scheme additions readied for
  RefSyst.
• Sea ice, SST assimilation
• Lake model snow on ice parametrization

11
Coupling with chemistry

• Before 2007 activities in coupling HIRLAM
  one-way or two-way to atm. chemical transport
  (ACT) models started in several HIRLAM countries
• May 2007 HIRLAM side meeting at COST-725
  workshop first attempt to create integrated plan
  for common activities
• Short-term one-way coupling improve usefulness
  of HIRLAM as input for ACT models
• Provision of relevant input variables
• Mass-conservation gt more accurate advection
  scheme
• Longer term two way coupling
• HIRLAM-CHEM branch

12
GLAMEPS

• Joint multi-model EPS system for HIRLAM ALADIN.
  Present status
• GLAMEPS initial laboratory setup (version 0)
  implemented at ECMWF. Meteorological testing
  ongoing.
• HIRLAM components of met.no, INM, KNMI
• ECMWF EPS/TEPS, physics perturbations,
• HIRLAM SVs as baseline for HIRLAM EPS
• ALADIN contributions from ZAMG (LAEF),
• met.hu (ALADIN SV)
• Development of new ensemble generation
• and postprocessing techniques on track
• End 2007/begin 2008 determine configura-
• tion for prototype distributed GLAMEPS
• system (v1). Continue parallel experimenta-
• tion in laboratory
• Continue pursuit of Eur. LAMEPS coopera-
• tion in TIGGE-LAM

13
GLAMEPS

• Model domain (for
• HIRLAM components)
• and ECMWF/TEPS
• targeting areas
• for Northern,
• Middle and Southern
• Europe

14
HIRLAM Reference system

• - Reference System repository is basis for
  HIRLAM developments
• Two reference platforms FMI RCR, ECMWF.
• Routine monitoring of RS on Hexnet, together with
  national versions
• 2007 RS extended to include HARMONIE and EPS
  components
• Aim Integration of syn/meso/GLAMEPS system
  environment (build, scheduling, monitoring and
  verification tools)
• Present versions HIRLAM 7.1, HARMONIE Cy32.
• HARMONIE code maintenance and updating together
  with AAA partners
• Common pool of computer resources at ECMWF for
  testing Reference System, GLAMEPS

15
