4 08 November, 2006OMSZ, Budapest Background NWP essential for operational weather forecasting. Maintenance and development of NWP systems beyond the capacity of most small NMSs. Therefore: Strong incentive to cooperate. The LACE Council decided on an evaluation of the RC LACE Project. Purpose: to assist in planning for the coming decade. Terms of Reference were drawn up.

5 08 November, 2006OMSZ, Budapest Consultations at RC LACE Centres: 1. Directorate 2. Local NWP teams 3. Technical and forecasting staff 4. Internal NWP users. Participated in meetings of: 1. LACE Council 2. LACE Steering Committee 3. Management Group 4. Vision Meeting at ECMWF. Extensive analysis of relevant documentation. Discussion of intermediate Evaluation Report. Activities of the Evaluators (pg 36)

6 08 November, 2006OMSZ, Budapest Short History of LACE (pp 5-7) Political changes in Europe in 1980s. Opportunities for co-operation in the Central European area. Meeting in Vienna (1990) to consider a Regional Centre for limited-area modelling. This was the embryo of RC LACE LACE Project established within a year.

7 08 November, 2006OMSZ, Budapest The French Government provided financial support to foster closer links. Météo-France offered a limited-area version of the ARPEGE model for operational use. This proposal included strong training and research components. The LAM-ARPEGE Project started in Toulouse in September 1991. Shortly it became ALADIN. The French Connection

8 08 November, 2006OMSZ, Budapest ALADIN provided an ideal basis for LACE. Several LACE scientists work in Toulouse. Nov. 1994: Co-operation framework agreement between RC LACE and Météo-France. Spring 1996: RC LACE Management Group established. Leader: Miroslav Ondráš. Plan A: Operational Regional Centre in Vienna. Later political changes in Austria prevented the establishment of the Regional Centre there.

9 08 November, 2006OMSZ, Budapest The Prague Phase 1997: CHMI acquire NEC computer. ALADIN ported to this system. March, 1998: First RC LACE MoU. Establishment of Regional Centre in Prague. June, 1998: ALADIN/LACE operations transferred to Prague. Scientists from all the participating institutes working at CHMI in Prague.

10 08 November, 2006OMSZ, Budapest Boundary conditions dispatched from Toulouse on a regular basis. Prague Centre was back-up centre for the reference ALADIN system software. ALADIN system was also run in operational mode in the other centres: Slovenia (1997), Hungary (1998), Austria (1999), Slovakia (1999), Croatia (2000). Each centre used combination of NWP guidance from the Prague Centre and local ALADIN.

11 08 November, 2006OMSZ, Budapest Centralized organization had many attractions … Concentrated research effort very effective. Common operational system maintained and developed with considerable efficiency. … but also significant tensions … Increasingly difficult to fulfill NWP requirements of all the participating institutes. Scientists reluctant to spend long periods away from their home institutes. Transfer of substantial financial resources away from the national institutes.

12 08 November, 2006OMSZ, Budapest Second RC LACE MoU signed in Oct. 2002. Decentralized phase began in January, 2003. RC LACE now Regional Co-operation LACE. MoU has been extended until the end of 2007. Each RC LACE Member responsible for its own operational NWP system. Scientific R&D coordinated within the project. The Current LACE Project (pp 7-8)

13 08 November, 2006OMSZ, Budapest Policy of Project determined by LACE Council (Directors of Member Institutes). LACE Steering Committee (LSC) is advisory body for Project. The Project Leader is Dijana Klarić (Croatia). The Management Group (MG): 1. Project Leader (PL) 2. ALADIN-LACE System Coordinator (ASC) 3. Data Manager (DM) 4. Working Group Leaders (WGLs). Structure of the Project

14 08 November, 2006OMSZ, Budapest Dynamics and Coupling Physical Parameterization Data Assimilation. EPS and Predictability Management Group appointments are reviewed annually. Working Groups

15 08 November, 2006OMSZ, Budapest RC LACE first group to officially join the ALADIN-2 Project (Jan, 2004). Intensive discussions on roadmap for ALADIN-2 and AROME. The AROME Project was started in 2000 at Météo-France. Goal: high resolution model for nowcasting and very short range forecasting. The ALADIN Project

16 08 November, 2006OMSZ, Budapest Combines parts of ALADIN and Meso-NH. Designed for resolution of c. 2 km. Interest within RC LACE for operational application of AROME. A framework for the transition: ALARO, similar to ALADIN with refined physics. LACE scientists are already active in Aladin/Hirlam collaboration (HARMONIE). AROME

17 08 November, 2006OMSZ, Budapest The European Context (pp 8-9) Europe a world leader in operational meteorology. RC LACE Members (5) in EU. RC LACE Members (5) in ECMWF. Possible EU move on centralization of operational meteorology … (?) Closer collaboration among NMSs is essential. EUMETNET a framework for collaboration. EUMET: All LACE members involved. WMO – Region VI. SRNWP: to be re-tasked / empowered.

18 08 November, 2006OMSZ, Budapest ECMWF World-leading forecast centre. Feb, 2006: Spatial resolution 25 km. Grid resolution of 10 km by 2015. RC LACE must aim for about 2 km on that time-scale.

19 08 November, 2006OMSZ, Budapest RC LACE Strengths (pp 9-12) Proven modelling expertise (Annex III) RC LACE and ALADIN. Relationship with Météo-France. Local operational ALADIN systems. Local NWP knowledge. Local applications. Budgetary control. Flexibility and Adaptability.

20 08 November, 2006OMSZ, Budapest RC LACE Weaknesses (pp 12-15) Manpower in NWP. Duplication of effort. Lack of identity, visibility. Internal communication. Complexity of the scientific planning process. Need to cover all NWP. Coordination of plans. Management structure. Quality of operational NWP systems.

21 08 November, 2006OMSZ, Budapest Break

22 08 November, 2006OMSZ, Budapest External Factors affecting LACE (pp 15-18) Activities of major NWP centres. User demands in LACE countries. Role of private service providers. NWP in universities. Government regulations. Developments in IT and communications.

23 08 November, 2006OMSZ, Budapest Other operational NWP systems in Europe that compete with LACE North-Atlantic Europe model (NAE) of UKMONAE (grid spacing 12 km; 8 km in 2009). Local model Europe (LME) of DWDLME (grid spacing 7 km). Local model LMK (LM-Kürzestfrist) of DWDLMK (grid spacing 2.8 km). University of Basel: NOAA-NCEP (NMM) modelNMM (grid spacing 13 and 2 km).

29 08 November, 2006OMSZ, Budapest University of Basel: Meteoblue NMM with grid spacing 2 kmNMM with grid spacing 13 km

30 08 November, 2006OMSZ, Budapest How LACE can respond to the NWP competition in Europe Provide better NWP quality, e.g. data assimilation. Provide higher reliability, e.g. hardware. Provide better price/performance ratio. Provide better customer service, e.g. documentation in local language. Provide more flexibility, e.g. product generation. Provide tailored products for customers, e.g. hydrology.

31 08 November, 2006OMSZ, Budapest Strategic NWP goals (pp 18-22) Convective scale NWP (AROME). Intermediate-scale (~5km) model (ALARO). Local data assimilation. Lateral boundary conditions. Regional ensemble prediction system. Increased automation of forecast process. Scientific scope of programme. Interaction with other NWP consortia.

32 08 November, 2006OMSZ, Budapest Task-sharing in RC LACE (pp 23-24) Balanced, voluntary contributions. Agreement on Lead Centres for specific areas. Efficient use of the scarce manpower available. Specialisation of the NWP teams. Ability of smaller NWP groups to provide their centres with a complete NWP system.

33 08 November, 2006OMSZ, Budapest 1. Common Observation Data Base (ODB) 2. Monitoring of observations, based on ODB 3. Flexible verification tool based on ODB 4. Data assimilation for intermediate NWP model 5. Detailed analysis of surface/soil parameters 6. Development and integration of intermediate NWP model 7. Preparation of a radar data composite 8. Nowcasting system based on ALARO/AROME and INCA 9. Ensemble Prediction System (EPS) 10. Standardized key post processing tools. Some Options for Task-sharing (pp24-28)

34 08 November, 2006OMSZ, Budapest 1. Common Observation Data Base (pg 24) The Observation Data Base (ODB) is a database software system developed at ECMWF. We propose a common centralised operational ODB for all LACE centres. It should be maintained at two different centres which will work as mutual backup. The common ODB, should store all GTS and local data from all LACE centres in the ODB. All other LACE centres can retrieve the observations from the ODB. Strict protection measures will be necessary.

35 08 November, 2006OMSZ, Budapest 2. Monitoring of data based on ODB (pg 25) Total counts of all observation types. Observation distribution maps for each analysis cycle. Rejected observation distribution maps for each cycle. Vertical profiles of observation fit to first guess, and analysis for each analysis cycle. Monthly maps of radiosonde - first guess biases. Vertical profiles of monthly mean and std of radiosonde biases, for bias-corrected areas. Monthly maps of mean and root-mean-square errors of drifting buoys.

36 08 November, 2006OMSZ, Budapest 3. Flexible verification based on ODB (pp26-27) Verification tool for LACE models, other regional models and the ECMWF model. Scheme designed and coded in Slovenia may serve as nucleus of the new system. Comparison of the quality of the models highlights strengths and weaknesses of the NWP systems. The centre responsible for verification should produce a quarterly verification report.

37 08 November, 2006OMSZ, Budapest 4. Centralized Data Assimilation (pg 27) The LACE centres will need a common regional model (grid ~5 km ALARO). This will provide the lateral boundary conditions of their meso-gamma scale AROME model. The data assimilation for this model should be performed in one LACE centre. The analysis should then be distributed to all LACE centres. The analysis of the intermediate NWP model should have higher quality.

38 08 November, 2006OMSZ, Budapest 5. Analysis of surface/soil parameters (pg 27) For Central Europe, high-resolution analysis of surface and soil parameters is important. Reliance on interpolated ARPEGE analysis for the surface and soil fields is not adequate. LACE should develop its own capability for high-resolution surface analysis. The expertise of the HIRLAM consortium should be exploited.

39 08 November, 2006OMSZ, Budapest 6. Development and integration of the intermediate model (pg 27) Centralised integration of the intermediate NWP model (grid spacing ~5 km) is possible. This will provide coupling files for LACE centres running convection-scale AROME model. This intermediate model must include data assimilation, including surface variables. The intermediate model may be driven by lateral boundary data from ARPEGE or ECMWF.

40 08 November, 2006OMSZ, Budapest 7. Preparation of radar data composite (p27-28) The convection-scale model AROME will assimilate radar data. The operational production of composite radar data of all the LACE countries is important. A number of scientific and technical problems must be solved. Expertise of other NWP consortia (HIRLAM, COSMO, UKMO) using radar should be used.

41 08 November, 2006OMSZ, Budapest 8. Nowcasting with INCA System (pg 28) INCA should be interfaced to the common ODB using local LACE data and ALARO forecasts. A centralized INCA run with domain covering all LACE countries should be considered. A local version of INCA, based on AROME forecasts, may also be developed.

42 08 November, 2006OMSZ, Budapest 9. Ensemble Prediction System (pg 29) The combined computer power available at the LACE centres should be used to run an EPS. Distributed computation of the EPS members and centralized evaluation/product generation. There are several scientific problems to be solved. Expertise of other NWP consortia running regional EPS should be used; EUMETNET SRNWP optional project?

43 08 November, 2006OMSZ, Budapest 10. Post-processing tools (pp 28-29) LACE scientists must work on a variety of downstream developments. To avoid duplication, standardised and portable post-processing tools should be developed. Since tools like Kalman Filter or MOS require observational data, the common ODB data base should be used.

44 08 November, 2006OMSZ, Budapest 1. Common ODB / Data Assimilation (Res. + Ops.) 2. Nowcasting system / EPS (Res. + Ops.) 3. Dynamics & Intermediate NWP model (Res. + Ops.) 4. Post processing / Surface Analysis (Res.) 5. Radar data composite (Res.) 6. Verification (Res.) Sketch of a possible configuration of Lead Centres (pg 30)

45 08 November, 2006OMSZ, Budapest Recommendations (pp 29-34) 1. Priority tasks for near future Common verification Data assimilation Evaluate ECMWF forecasts as LBC data Post-processing Focus on ALADIN, ALARO, AROME.

46 08 November, 2006OMSZ, Budapest 2. Strategy and Planning (pg 31) Council should adopt a general 10-year strategy of RC LACE, updated every five years. LSC should formulate a detailed 2-year plan, updated annually. Survey of user requirements. LSC should co-ordinate and harmonize user requirements.

47 08 November, 2006OMSZ, Budapest 3. Management Structure (pp 31-32) Council Twice-yearly Council meetings. Reduce amount of papers for the meeting. Material dispatched in timely fashion. Short summary documents. Appointment of new management staff. LACE Steering Committee (LSC) Receive papers two weeks before meeting. Reduce time spend on technical issues. Increase time for strategic issues. Highlight training needs and co-ordinate training.

48 08 November, 2006OMSZ, Budapest Project Leader (pg 32) Position should be full-time (or at least 80%). Improve international visibility of RC LACE. Pro-active in putting RC LACE objectives on international agenda. Act as RC LACE representative at key meetings and conferences. Management Group (pp 32-33) Core Group (80%) for long-term research tasks. The WG Leaders need formal control of scientists. Improve flow of information between WGs. ASC and DM should be a half-time positions. Terms of Reference for ASC and DM separated. Longer time-scale for management appointments.

49 08 November, 2006OMSZ, Budapest 4. Internal & External Communications (pp 33-34) A recurring theme: lack of recognition of RC LACE outside the ALADIN Community. WWW as repository for documentation. Visual Image of RC LACE. Communications with other NWP Consortia. Management Group should explicitly consider possibilities for collaboration with other groups when defining scientific plans for RC LACE.
