7. SERA Tasks (WWRP Strategic Plan) 1.Finalize the initial WGSERA membership and establish a three-year WG meeting schedule with the WWRP Secretariat - done 2.Clearly define mutual and complementary roles with the ICSU Planning Group on Natural and Human induced Hazards and Disasters (ICSU IRDR). I. forming a joint ICSU-IRDR/WMO WWRP-SERA Working Group as recommended by CAS II.having an Ex Officio representative of WMO- WWRP on the IRDR Steering Committee 3.Establish a basic inventory of related projects, capacity, contacts, and interest in SERA through consultation with WG members, NMHSs, WWRP WGs, THORPEX Regional Committees, other WMO programmes, professional societies, and academic institutions. 4.Develop the architecture and content for an international SERAwx web resource for social scientists and users (either on the WMO-WWRP site or an external server). 5.Joint meeting/session with the JWGVR to define and scope a series of regional and sector based case applications that cut across nowcasting, meso-, and sub-seasonal scales of prediction/decision-making – 27 to 29 September 2010 6.Develop, test and evaluate a SERA-friendly TIGGE dataset from multiple user-perspectives in conjunction with the THORPEX-TIGGE WG. 7.Prepare an outline scoping out a multi-year project to assess the global societal and economic benefits (and costs) of weather information.

8. SERA Meeting #1 Decisions/Actions General  Many WWRP projects were conceived and planned without substantive SERA involvement/consultation at their inception—this must change. Potential funding opportunities for SERA-related interests should be identified.  The WWRP Secretariat/JSC Chair should seek approval to allocate new funds (up to US$50k/yr) for basic societal and economic research and applications to advance SERA initiatives.  It is recommended that the WWRP Division should acquire familiarity with and experience managing or conducting socio-economic research. Africa  A fully-costed African THORPEX Implementation Plan would make it easier to identify and obtain funding.  A approach to using the MunichRe impact event information in support of the THORPEX Africa High Impact Weather Information System database will be developed.

9. SERA Meeting #1 Decisions/Actions Decision/Action: WG SERA will develop a Warning Information System “Pre- Demonstration Project” which will include a GlFS-TIGGE/TIGGE-LAM evaluation component and applications derived from existing activities (e.g., MeteoAlarm, MAP D-Phase, GIN, SWFDPs other EPS applications).

24. Observational network in the region of the Games Current atmospheric monitoring network is sparse and not representative enough given the complexity of the region and high Olympic demands. Ground-based observations are mostly concentrated along the coast. Vast sea area from one side and nearby high mountains (up to 3 km and more) on another side of Krasnaya Polyana are virtually uncovered with contact observations. In 2009-2010 more than 30 automatic stations should be added to enhance the existing observational network. Major part of these new stations will be located in close proximity to the Olympic venues. + 3-5 moored sea buoys 100-150 km away from the coast; + 8 mobile automated meteorological stations; + More frequent sounding at the nearest aerological stations; + 5 Dopplers instead of existing outdated radars; + Several profilers (2-3) …. (partially completed) Sochi-2014

25. PROPOSED THEMES for the NOWCASTING/MESOSCALE RDP/FDP  Observations for winter nowcasting over complex terrain  Diagnosis, nowcasting, and short-range forecasting of multi-weather elements – wind speed and wind gust, visibility, fog, precipitation intensity and time  Mesoscale deterministic and ensemble prediction  High resolution deterministic and ensemble prediction (including downscaled surface systems and fog models)  Microphysics and other physical parameterizations  Assimilation of high-resolution data (including radar and other observations)  Verification based on remote sensing data  Societal Impacts... all these issues to be discussed at kick-off meeting.

28. Forecast verification method intercomparison project (ICP) Several members of the JWGFVR have participated in the ICP, which is an effort to provide useful information on new verification approaches that have been developed in the last few years. The initial focus has been on spatial verification approaches, including object-based methods, scale separation approaches, neighborhood methods, and field morphing approaches. The results of these studies will be published as a special collection in the journal Weather and Forecasting. Outreach and other activities The JWGFVR continues to maintain a website on verification: http://www.bom.gov.au/bmrc/wefor/staff/eee/verif/verif_web_page.html which contains a wide variety of information, and to maintain a discussion group on verification methods. http://www.bom.gov.au/bmrc/wefor/staff/eee/verif/verif_web_page.html Joint Working Group on Forecast Verification Research (JWGFVR)

32. CXML data exchange Recommendations from 2006 International Workshop on Tropical Cyclones The WMO should take all necessary action to: improve the communication between operational centres and facilitate the dissemination of all tropical cyclone-related NWP products, such as the deterministic and ensemble forecasts (including the full set of ensemble runs), make them available to all RSMCs, TCWCs and researchers in real-time. WMO should investigate the most appropriate ways to achieve this goal: coordinate with the NWP and major operational centres (RSMCs and TCWCs) in order to define a set of resolvable tropical cyclone characteristics to be provided and timely disseminated by the NWP centres through the GTS (e.g. centre location, minimum sea level pressure, max wind, wind radii by quadrants, etc…) and define the appropriate standardised format, and/or find a WMO-sponsored dedicated reference centre (similarly to what has been done with the Severe Weather Information Centre for the dissemination of the analysis and forecast products issued by the main operational centres) able to host and maintain a single global data base of the tropical cyclone forecasts originating from the different NWP centres.

35. An update of possible consequences of climate change on tropical cyclones has been completed and published by the TC Panel’s Expert Team on Climate Change Impacts on Tropical Cyclones in the March 2010 issue of the peer- reviewed journal Nature Geoscience. The experts concluded that the total number of tropical cyclones worldwide will likely either decrease or remain unchanged. However, a likely increase in tropical cyclone intensity means that the frequency of the strongest tropical cyclones will more likely than not increase under the projected warming scenarios.

36. Relative to improvements in tropical cyclone tracks, progress in the prediction of the intensity and genesis of tropical cyclones by NWP systems has proven more difficult. Recent progress has been achieved by increasing model resolution. In addition, based on THORPEX research, there is strong evidence that targeted observations for tropical cyclones do have a beneficial impact and the resultant socio-economic benefit here can be large. To address these issues, TCP is working closely with WWRP to promote the research and developments (R&Ds) in tropical cyclone prediction and its application to operational forecasting. The two Programmes jointly organize various international forums on a regular basis with a view to strengthening the interactions between researchers and operational forecasters, including the International Workshop on Tropical Cyclone (IWTC) and the International Workshop on Tropical Cyclone Landfall Processes (IWTCLP). Efforts are also made for active involvement of researchers in the annual/biennial sessions of TCP regional bodies. Tropical Meteorological Research

38. Seventh International Workshop on Tropical Cyclones (IWTC-VII) (15-20 November 2010, La Réunion, France) The main objectives of these workshops are: 1) to examine current knowledge, forecasting and research trends on tropical cyclones from an integrated global perspective 2) to report on these aspects and to offer recommendations for future forecasting studies and research with special regard to the varying needs of different regions. The IWTC is one of WMO’s major quadrennial workshop series organized by WWRP and Tropical Cyclone Programme (TCP). It is a special and unique gathering of tropical cyclone researchers and warning specialists from all regions affected by tropical cyclones, including those from Members belonging to the WMO TCP regional bodies.
