  1. THORPEX: THe Observing system and Predictability Experiment – A World Weather Research Program • INTERNATIONAL PROGRAM OBJECTIVES • SCIENCE GOAL: • Promote research leading to new techniques in: • Observations (OBS), • Data assimilation (DA), • Forecasting (FCST), and • Socioeconomic Applications (SA) • SCIENTIFIC RESEARCH MUST ENABLE SERVICE GOALS • SERVICE GOAL: • Accelerate improvements in utility of forecasts for high impact weather • THORPEX ANSWER: • Develop new paradigm for weather forecasting through • Enhanced collaboration • on international level • between research & operations

  2. STATUS OF PLANNING International Science Plan: Completed & accepted (Dec. 2005), 51 pages International Implementation Plan (TIP): Completed & accepted (Febr. 2005), 93 pages US THORPEX Plan First Draft ready in Aug. 2004 Under revision NOAA THORPEX Science & Implementation Plan Completed in June 2003, 52 pages

  3. NOAA SERVICE GOAL: ACCELERATE IMPROVEMENTS IN 3-14 DAY FORECASTS3-7 day precipitation forecasts8-14 day probabilistic daily weather forecastsNOAA SCIENCE OBJECTIVE: REVOLUTIONIZE NWP PROCESS NEW NWP Sub-systems developed in coordination End-to-end forecast process Strong feedback among components Two-way interaction Error/uncertainty accounted for TRADITIONAL NWP Each discipline developed on its own Disjoint steps in forecast process Little or no feedback One-way flow of information Uncertainty in process ignored SOCIOEC. SOCIOEC. SYSTEM SYSTEM INTEGRATED, ADAPTIVE, USER CONTROLLABLE


  5. STATUS - NOAA • Grant program • 12 studies funded at slightly reduced level • 2 on Observing System • 5 on Data Assimilation • 3 on Predictability/Forecasting • 1 on Socio-Economic Applications • 1 on Cross-Cutting • IPY Planning • Pre-Proposal (Short-Term Arctic Predictability, STAP) submitted, Jan. 2005 • Predictability of weather, sea ice, ocean wave, and land surface in the Arctic on 3-90 days • One of 10 NOAA submissions • Coordinated with a group of 10 PIs (JCSDA, SIMMS, OAR, OGP, NIC, NWS, SIP) • Full plan due June 2005 • Need to coordinate with US/NA/International THORPEX plans/efforts • North American Ensemble Forecast System (NAEFS)

  6. NORTH AMERICAN ENSEMBLE FORECAST SYSTEM • Joint research/development with Met. Services of Canada & Mexico • Combine Canadian / US ensemble systems • Seamless forecasts over borders and lead times • Share development and computer resources • Better represent forecast system related uncertainty • Timeline • May 2003 Kick-off Workshop • Nov 2003 Research, Development & Implementation Plan complete • Sept 2004 Initial Operational Capability • Nov 2004 Inauguration Ceremony & 2nd Workshop • High level management, press coverage • Link with GEOSS • Example for GEOSS empowered applications • Phased operational implementation • March 2006, 2007, 2008 • Prototype for THORPEX Interactive Grand Global Ensemble (TIGGE)

  7. ISSUES • Long term budget planning • Need to bring budget and RDI (research, development & implementation) planning in sync • Mismatch between science plan/high level promises and available resources • Current 1.3M (2.3M for 06?) budget does not allow full NOAA participation • Cannot take advantage of IPY-related opportunities • Cannot fulfill GEOSS expectations (THORPEX IS GEOSS for global weather forecasting) • Cannot take full advantage of other international collaborative efforts • Cannot achieve NOAA’s goal of promoting global environmental safety • Immediate concerns • Need funding for transition of grant-based research into operations • Entering 2nd year of grant research • Must find a solution, otherwise good efforts may be wasted • Operational Test Center must be established (jointly with JCSDA) • Need funding for directed research/development (by NOAA Labs & others) • To fill gaps in program (new fcst system will be as good as its weakest point allows) • Foster interagency collaboration • IPY offers good opportunity (and challenge)

  11. THORPEX: A GLOBAL ATMOSPHERIC RESEARCH PROGRAM NOAA LONG-TERM RESEARCH PROGRAM PLAN INTRODUCTION New forecast paradigm SCIENCE PLAN Major Themes Open Science Questions Research and Development Tasks IMPLEMENTATION PLAN Work Plan Deliverables Performance measures Education/Outreach Path to Operations APPENDIX Link with NOAA Strategic Goals NWS STIP Process

  12. NOAA THORPEX PROGRAM OVERVIEW • ANSWER SCIENCE QUESTIONS Advance basic knowledge, directed explicitly toward NWP applications Each task must be conceived as part of overall program • DEVELOP NEW METHODS Sub-system development Academic research Cross-cutting activities Academic + operational centers Infrastructure / Core tasks Facilitate other activities - Strong agency involvement Operational Test Facility Real time test and demonstration • RECOMMEND/PREPARE OPERATIONAL IMPLEMENTATION Integral part of program Strong participation by operational centers

  13. SCIENCE QUESTIONS – ACTIVITIES Observing system (OBS) Data assimilation (DA) Forecast procedures (FCST) Socio-economic Applications (SA) Cross-cutting activities Core tasks

  14. SCIENCE QUESTIONS – ACTIVITIES - 1 OBSERVING SYSTEM New in-situ and remote instruments/platforms to complement existing network Adaptive observing instruments/platforms For large data sets Super-obing etc prior to OR within data assimil. (Joint work with data assimilation) Obs. error estimation (correlated/uncorrelated)

  15. SCIENCE QUESTIONS – ACTIVITIES - 2 Observing system DATA ASSIMILATION Improve techniques Forward models, transfer codes Thinning of data Treatment of data with correlated errors Advanced methods to use case dependent covariance 4DVAR research, e.g., continual update of error covariance Ensemble based techniques Treatment of model errors Adaptive observing techniques Quick use of targeted data (“pre-emptive” forecasting) Methods in the presence of Strong non-linearities Model error Effectiveness of targeted data in analyses/forecasts Effect on climatological applications of data

  16. SCIENCE QUESTIONS – ACTIVITIES - 3 Observing system Data assimilation FORECAST PROCEDURES Initial ensemble perturbations (Joint with data assimilation) Role of non-modal behavior Separate model related error from initial value errors Systematic vs. random errors Atmospheric features most affected Critical model features responsible for different errors Improve model formulation to reduce errors (Coupling techniques) Techniques to account for remaining uncertainty in ensembles Adaptive modeling and ensemble techniques

  17. SCIENCE QUESTIONS – ACTIVITIES - 4 Observing system Data assimilation Forecast procedures SOCIO-ECONOMIC APPLICATIONS Probabilistic forecasting Statistical post-processing New procedures for intermediate and end users Add-on costs of new THORPEX NWP process Cost of data from multi-use satellite platforms (Joint with Observtns.) Incremental societal/economic benefits of new NWP process New NWP verification measure Societal aspects of new adaptive NWP procedures Equitable use of NWP resources

  18. CROSS-CUTTING ACTIVITIES Integrating NWP procedures from four sub-systems Observing System Simulation Experiments (OSSEs) Data needs of NWP What variables/resolution/accuracy required Instrument/platform neutral assessment What instruments/platforms can provide data needs Existing and new in-situ & remote platforms Adaptive component to complement fixed network Most cost effective solution Relative value of improvements in four sub-systems Improvements in which sub-system offer best return? Reallocation of resources Test of proposed operational configurations Major field program if needed Cost/benefit analysis - Select most cost effective version

  19. CORE TASKS Needed for efficient research & planned operations Strong agency involvement THORPEX data base (observations, forecasts) Information Technology challenge High data volume Transmission Storage of data Foster collaboration in critical areas Workshops (Societal and economic impacts) Joint proposals – Interdisciplinary collaboration Critical in past programs like FASTEX Test-bed – Pathway from research to operations Formal procedure for researchers to follow Melting pot for new ideas Venue for cross-cutting activities

  20. NOAA THORPEX OBJECTIVES • 1) Develop new forecast procedures leading to • Improved operational NWP forecasts; and • Develop/adapt cost/benefit tools to measure resulting societal impact • ULTIMATE MEASURE OF SUCCESS • The overall success of the NOAA THORPEX program will be measured in a unique and comprehensive way. The program will be considered successful if the newly developed cost/benefit analysis tools (point 3 above) indicate that the forecast improvements (point 2) due to the new THORPEX procedures (point 1) can be achieved operationally in a cost-effective manner. That is, the incremental economic and societal benefits associated with the use of the new THORPEX forecast procedures outweigh their implementation and maintenance costs.

  21. LINK WITH NOAA MISSION GOAL NOAA’S 3rd MISSION GOAL – sounds like excerpt fromTHORPEX doc.: NOAA will “provide integrated observations, predictions, and advice for decision makers to manage… environmental resources”. Mission strategies and measures of success directly correspond with THORPEX Sub-program areas: NOAA MISSION STRATEGY THORPEX FORECAST COMPONENTS Monitor and Observe Observations Understand and Describe Data Assimilation Assess and Predict Forecasting Engage, Advise, and Inform Socio-economic Applications Different Line Offices responsible for various forecast components – NEED FOR NEW MATRIX MANAGEMENT CONCEPT FOR INTEGRATION

  22. LINK WITH NWS STIP PROCESS National Weather Service (NWS) – NOAA’s operational weather forecast provider NWS Science and Technology Infusion Plan (STIP) – Operational requirements should motivate all service oriented research Research must have thread to operations & Credible path to operational implementation SCIENTIFIC RESEARCH MUST ENABLE SERVICE GOALS THORPEX seeks advanced knowledge on two fronts: Nature (atmospheric and related processes) Forecast procedures (OBS, DA, FCST & SA techniques) Integrating knowledge from two areas leads to new forecast paradigm of INTEGRATED, ADAPTIVE, AND USER CONTROLLABLE FCST PROCESS
