1 RDP/FDP FROST-2014: state of affairs Dmitry Kiktev Hydrometcentre of Russia / Roshydromet 18-19 July 2013 WWRP JSC6 Meeting, Geneva

2 Goals of RDP/FDP FROST-2014: To improve and exploit: – high-resolution deterministic mesoscale forecasts of meteorological conditions in winter complex terrain environment; – regional meso-scale ensemble forecast products in winter complex terrain environment; – nowcast systems of high impact weather phenomena (wind, visibility, precipitation type and intensity etc.) in complex terrain. To improve the understanding of physics of high impact weather phenomena in the region; To deliver deterministic and probabilistic forecasts in real time to Olympic weather forecasters and decision makers. To assess benefits of forecast improvement (verification and societal impacts) To develop a comprehensive information resource of alpine winter weather observations;

22 JSC5 Decisions /Actions Required 44. JSC endorsed the FDP/RDP proposal for Sochi Winter Olympic Games in 2014, but expressed concern that the proposal timelines would not provide a stable software environment for the forecasters, thus jeopardizingthe provision of accurate forecast information. It was also suggested that trial periods and decided training activities be conducted to expose the Olympic forecasters to the new models.

23 Grapical Tools

24 COSMO-RU02 Horizontal resolution 2.2 km Grapical Tools

25 Forecaster role: Best forecasts include a forecaster with conceptual models of local process evolution and access to automated tools. FROST-2014 is intended as an end-to-end project. Its products will be used by local forecasters for meteorological support of the Olympics and preceding test sport events. The last chance to introduce new FDP-products to forecasters will be training in October 2013 (before that there will be training in August). Forecasters training Forecasters trainings are held on regular basis; Participants are involved into provision of meteorological services for sport test events.

26 Forecast Verification METv4.0+ (Model Evaluation Tool / NCAR) software was adapted for the FROST-2014 needs; Two papers on forecast verification for Sochi region were submitted; Official forecasts are planned to be available for further verification along with the project objective forecasts Distributed verification activity ? (Roshydromet–FMI (JWG on Verification Research))

27 Station-based diagnostic verification on example of COSMO-RU2 forecasts The values relate to the histogram bin centers. Green lines denote the bin sample volume of at least 20 pairs (sample stability). Calibration implies a shift of the forecast mean-median to the leading diagonal. The t2m area outside the green strip indicates sample instability (calibration uncertainty). Importance of the above diagnostic verification for decision-making. Parameter: T2m Station: RKHU1, (Aibga) 2250 m. Period: winter 2011-2012

28 Polygonal Verification for SOCHI_COAST (19 Stations), ADLER_COAST (8), KR_POLYANA (22), ALPICA(20) Local Climatology: Coastal zone (0 – 300 m), Submountane zone (300-600 m), Alpine zone (600 – 2500 m).

29 SKILL SCORING for the polygons Category T2m > 0 C forecasts. Hanssen-Kuipers discriminant, (Peirce skill score). Period: winter 2011-2012 Obs-Frcs matching: for every hour with 10 min obs window; several interpolation methods to COSMO grid were tried Measures: Categorical (contingency tables) and continuous scores, 95% confidence intervals Sochi coast coastal cluster Kr Polyana

30 a b c d ef Sochi coast coastal cluster Kr Polyana MEAN ERROR RMSE

31 COSMO-RU2 T2m Mean Errors for Krasnaya Polyana polygon for two consequent winter seasons: Mean Error changed its sign ! 01.12.2011-31.03.2012 01.01.2013-15.03.2013 Potential reasons behind: - effects of inter-annual changes in the large-scale circulation (winter 2012-2013 was unusually warm) ? - changes in the driving global model ? - …………..

32 Radar max reflectivity versus NMMB column max reflectivity and 1-hour precipitation total with 6 hrs lead time With precautions it will be tried as a ground for spatial verification

33 Social and Economic Impacts Socially significant project application areas: Education Understanding Transfer of technologies Practical forecasting – first guess for operational official forecasts. Integrated project forecasts will be used as a first guess for the data feed to the Olympic information system (supported by IOC partner Atos Origin) and Olympic Broadcasting Services (OBS). Two Earths (with and without FROST-2014) are needed for the project impact assessment !
