The WWRP Forecast Demonstration Project MAP D-PHASE on flood forecasting in the Alps Authors: Arpagaus, Dorninger, Hegg, Montani, Ranzi, Rotach Presentation: Saskia Willemse, MeteoSwiss Technical Conference preceding CAS XV16-17 November 2009, Incheon, South Korea
Outline • D-PHASE essentials • Key elements and characteristics • Achievements and outreach • Lessons learned & future developments
D-PHASE essentials • Forecast Demonstration Project for MAP • 2nd WWRP Forecast Demonstration Project (FDP) • Focus on heavy precipitation and flood forecasting • D-PHASE:Demonstration of Probabilistic Hydrological and Atmospheric Simulation of flood Events in the Alpine region • D-PHASE Operations Period (DOP): June to November 2007 (COPS & “MAP season”) • 9 countries involved • 30 atmospheric models / 7 hydrological models in over 40 catchments
Distributed real-time end-to-end forecasting system Medium range Short range Now-casting
Key elements of D-PHASE • Centralised Visualisation Platform (forecasts & alerts; in real-time); • Data archiving ( COPS); • Nowcasting tools; • Systematic integration of end users; • Evaluation, objective and subjective.
Overview: Is there any alert? Where? 8.8.2007, ~ 15:00 local time
More details: Which models alert? 8.8.2007, ~ 15:00 local time
Key characteristics of D-PHASE Samelook and feel for all models (colour coding etc.) joint alert definitions same script to determine alerts same programs for plots Full information is provided to the end user; the diversity of forecasts is visible Hierarchical layout allowing to zoom in –from an overview to the details
Same plots (variables, colour coding, …) for all models 8.8.2007, ~ 15:00 local time
JDC = Joint D-PHASE/COPS Verification data set Achievements • Unprecedented data set model intercomparison / validation process studies (with COPS) test beds (COST 731 for Data Assimilation, HEPEX) Integrated Mesoscale Research Environment (WG MWFR) • Demonstration of operational coupling of hydrological and meteorological models
Achievements Participation of users 45 end users institutions (civil protection ...) workshops & questionnaires feedback exchange of needs Scientific results advances in ensemble hydrological modelling radar ensemble, high-resolution EPS, high-res reforecasting, fuzzy verification, economic forecast value, …. 21 peer reviewed papers 72 reports and ext. abs. 165 presentations BAMS Paper, Sept 2009
Achievements Findings high resolution atmospheric models prove better importance of ensemble modelling Single-model ensemble substantially gains from calibration value of ‘ensemble observations’ (radar ensemble) Relative value param. conv. resolved conv.
Outreach D-PHASE/COPS data set as testbed for COST / HEPEX, IMRE D-PHASE as role model for Swiss natural hazards platform (GIN) VP still up and running until GIN goes life…. Many operational hydrological services started to use model-based input (I, CH, D) Funded research projectsPriority Programme QPF (several) FP7 Imprints Austrian Science Foundation (VERITA) FOEN, Switzerland Univ Hamburg funding
Lesson learned 1 End users feedback • Resolution needs to further increase (and will) • Take end users early on board • EPS’s need careful support (for interpretation) • ‘Ensemble thinking’ for air pollution modelling, heat wave warnings, health impact (e.g., pollen), …
Lesson learned 2 Interoperability • International agreements needed (procedures, thresholds) • Multi-model availability by far exceeds multi-model use… • In the transformation to operations the commercial value of meteorological data is a barrier
Finances Ways of dissemination within WMO / member countries ‘increase involvement of users and NMHSs from developing countries in future FDP’s...’ Themes / activity: WWRP could also propose themes future directions Future FDP‘s
