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
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.
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;
3+4DV, syn+meso– 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.
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
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 => more accurate advection scheme
• Longer term: two way coupling– HIRLAM-CHEM branch
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 GLAMEPSsystem (v1). Continue parallel experimenta-
tion in laboratory• Continue pursuit of Eur. LAMEPS coopera- tion in TIGGE-LAM
GLAMEPS
Model domain (for
HIRLAM components)

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
Reference system
