  • 10. - Closure of the session
    The Second Session of the Expert Team on Wind Waves and Storm Surges (ETWS-II) is expected to close by noon on Saturday, 24 March 2007.
  • 2. - Reports
  • 2.1 - Report of the Chairperson of the Team
  • 2.2 - Report of the Secretariat
    The Team will be presented with reports by the Chairperson of the Team and the Secretariat on the activities and actions taken since the First Session of the JCOMM Expert Team on Wind Waves and Storm Surges (ETWS-I). These reports will also touch the overall results of JCOMM-II (Halifax, Canada, September 2005), the Fifth Session of the JCOMM Management Committee (MAN-V) (Geneva, Switzerland, October 2006) and the Third Session of the JCOMM Services Coordination Group (SCG-III) (Exeter, United Kingdom, November 2006), as well as actions taken since these sessions.
  • 3 - Activities
  • 3.1 - Operational wave forecast verification project
    Five centres (ECMWF, Met Office (UK), Fleet Numerical Meteorology and Oceanography (USA), Canadian Meteorological Centre and NCEP (USA)) have been participating in numerical wave forecast verifications. This is one of the most important activities of the ETWS in support of MetOcean information and maritime safety services, in particular, continue to be the operational wave forecast verification project. The JCOMM Technical Report No. 30: Verification of Operational Global and Regional Wave Forecasting Systems Against Measurements from Moored Buoys, was published in 2006. The project now includes eight centres, and the goal is to continue to add new participants including regional participants where appropriate, and expand the scope of the inter-comparison as feasible. The Team will be invited to review and expand the project for verifying operational wind wave model outputs. It will also be requested to develop procedures for distribution of information on the wave forecast verification scheme.
  • 3.2 - Extreme wave database
    Currently, a proposal is being developed between the ETWS and the Expert Team on Marine Climatology (ETMC) of the JCOMM Data Management Programme Area (DMPA) for the establishment of a JCOMM Extreme Wave Database for use in model validation and validation of remotely sensed waves, where such models and algorithms suffer from lack of sufficient data. This database would be populated with measured wave data where the significant wave height exceeds 14 metres, with appropriate accompanying metadata. The Ninth Waves Workshop expressed a strong interest in expanding the scope of the extreme wave data archive to include satellite estimates as well as data from wave radars such as WaMoS or MIROS. The rationale for the database is to have a relatively small and manageable set of extreme storm sea states for comparison with wave forecast and hindcast products, model development and evaluation and satellite sensor calibration and validation. It has been suggested that an archive of storm surge events for similar purposes should also be considered. The Team will be invited to review this proposal for the extreme wave database, and to make suggestions and comments as appropriate.
  • 3.3 - Wind, Wave and Surge Climatologies
    The Team will be invited to prepare strategies to continue monitoring studies of wind wave, storm surge and surface wind climatologies. It will also be invited to prepare an update of the inventory of hindcast wind wave and storm surge climatologies.
  • 3.4 - JCOMM Extreme Water Level (JEWL) project
    The SCG-III has developed a concept proposal for the development of a cross-JCOMM pilot project on Extreme Water Levels (JEWL). The Team will be presented with this proposal and will discuss potential contributions to this project.
  • 4. - Guides and relevant publications
  • 4.1 - Guides
  • 4.1.1 - Guide to Wave Analysis and Forecasting
    The Guide to Wave Analysis and Forecasting (WMO-No. 702) was first published in 1988 and its second edition was published in 1998. This Guide is designed to enhance the provision of up-to-date information and guidance material on all aspects of ocean-related activities of National Meteorological Services. The Team will be invited to review the contents of the Guide, advise on the need for future updating, and propose additional material, as appropriate.
  • 4.1.2 - Guide to Storm Surge Forecasting
    JCOMM-II urged the ETWS to complete preparations of the Guide to Storm Surge Forecasting during the intersessional period. An expert meeting was convened at the WMO Headquarters, in Geneva, Switzerland, from 8 to 10 February 2006, to develop the Table of Contents of the Guide and adopt an implementation plan for its preparation. The Team will be invited to review the first draft of this Guide and to make suggestions and comments, as appropriate.
  • 4.1.3 - Dynamic parts of the Guides
    Specific Technical Reports have been produced by the Team, such as proceedings of meetings (e.g., the Ninth Waves Workshop), questionnaire results on wave models and databases, descriptions and links to related material such as the online ERA40 and MSC50 wave atlases. Such reports would be included in the Dynamic part of the Guide to Wave Analysis and Forecasting. Similar reports on Storm Surges modelling, hindcasting and forecasting could be developed by the Team. Under this agenda item, the Team will be requested to develop a strategy and implementation plan for the preparation of the Dynamic part of the Guides.
  • 4.2 - Technical Reports
    Since JCOMM-II (Halifax, Canada, 19-27 September 2005), two JCOMM Technical Reports were published in accordance with the identified interest of wave forecasters in the wave model verification and satellite data assimilation in wave models. During the intersessional period, the completion of Technical Reports on wave climate effects on design criteria and review of boundary layer wind fields is also planned. The Team will be requested to identify specific interests and develop plans to prepare technical reports as required.
  • 5. - Observations Requirements
    The ETWS Chairperson made a presentation to the Twenty-second Session of the JCOMM Data Buoy Cooperation Panel (DBCP) on the requirement of the SPA for enhanced high-quality, long-term wave measurements in the global oceans in support of Maritime Safety Services. The Panel supported the requirement for additional high-quality wave measurements in under-sampled areas of the world oceans in support of the activities of the SPA, and urged the ETWS to work in conjunction with the Observations Programme Area (OPA), through its component groups and sub-groups including DBCP, to produce a more detailed set of requirements for additional high-quality wave measurements as soon as possible. The Team will be invited to develop a set of requirements for waves, as well as other observational matters related to wind wave and storm surge.
  • 6. - Workshops and Capacity Building
  • 6.1 - Technology transfer
  • 6.1.1 - Storm Surge Symposium
    The First JCOMM Scientific and Technical Symposium on Storm Surges Modelling, Hindcasting and Forecasting is planned for 2-6 October 2007 in Seoul, Korea. This scientific workshop will complement other international efforts, including the series of capacity building workshops on storm surge and wave forecasting organized by JCOMM and the WMO Tropical Cyclone Programme, as well as efforts by JCOMM in developing ocean-related hazard warning systems. The focus of the workshop will be similar to the very successful JCOMM scientific workshops in other related fields, including the International Workshop on Wave Hindcasting and Forecasting and the CLIMAR Workshop on Advances in Marine Climatology. The Management Committee, at its Fifth Session (MAN-V), and the Services Coordination Group, at its Third Session (SCG-III), endorsed the proposed the upcoming Storm Surge Symposium. The Team is invited to consider its contribution to this Symposium.
  • 6.1.2 - JCOMM Training workshops
    A workshop on wind wave and storm surge analysis and forecasting for Caribbean countries was held in Halifax, Canada, from 16 to 20 June 2003. A number of members of the Team joined the workshop as lecturers. The Team is expected to provide comments regarding the organization of other training workshops. The Team will also explore various CB alternatives to traditional (week-long) workshop settings and how the ETWS might contribute especially at the regional level.
  • 6.1.3 - Development of e-learning modules (OceanTeacher, Bilko)
    During the SCG-III, the Team was requested to develop e-learning modules, such as OceanTeacher and/or Bilko lessons. Previous capacity building activities of the ET have produced much useful material that could be adapted to this end. The Team therefore will be invited to develop a strategy and implementation plan for the preparation of these e-learning modules. The team will also explore various CB alternatives to traditional (week-long) workshop settings and how the ETWS might contribute, especially at the regional level.
  • 6.2 - Other workshops and conferences
    The ETWS will participate in the organization and planning of major technical workshops related to waves and surges, and specifically organize technical workshops, as appropriate, for waves and surges to facilitate information exchange among world experts in these fields and provide material for the Dynamic parts of the Guides. In addition to the Ninth and Tenth Waves Workshops and the Storm Surge Symposium, the ETWS will certainly continuing to play a role in the CLIMAR meetings led by the ETMC, ensuring that waves and surges are well represented within the marine climatology envelope. The International Association of Oil and Gas Producers (OGP) has expressed interest in a workshop on the potential impact of climate change on future design criteria, which relates to the planned technical report on the subject. The WMO has been approached to host such a meeting at the end of March 2007 to coincide with the ETWS-II. The Team will also be invited to consider its contribution to other workshops and conferences relevant to the activities of the Team.
  • 7. - Cooperation with other bodies
  • 7.1 - Expert Team on Maritime Safety Services (ETMSS)
    The Second Session of the JCOMM Expert Team on Maritime Safety Services (ETMSS) (Angra dos Reis, Brazil, 24 to 27 January 2007) discussed possible interactions between the ETWS and ETMSS regarding sea state information and a definition of risk indicators, especially regarding dangerous and complex seas and the risk of rogue/freak waves. The Team will be invited to consider this issue and give advise on future procedures.
  • 7.2 - Expert Team on Marine Climatology (ETMC)
    Based on the discussion on previous agenda items, especially under the agenda item 3, the Team will be invited to discussed interactions between the ETWS and the ETMC, and develop a proposal for a joint work plan that would be presented to the Second Session of the ETMC (Geneva, Switzerland, 26 to 27 March 2007)
  • 7.3 - Expert Team on Climate Change Detection and Indices (ETCCDI)
    Under this agenda item, the Team will be presented with the outcomes of the First Session of the Expert Team on Climate Change Detection and Indices (ETCCDI) (Niagara-on-the-Lake, Ontario, Canada, 14 to 16 November 2006) that requires actions by the Team. The Team will be invited to consider its contribution to the work of the ETCCDI.
  • 7.4 - WMO Tropical Cyclone Programme (TCP)
    The WMO Tropical Cyclone Programme has been organizing a series of workshops on storm surges, waves and ocean circulation forecasting in the South China Sea region in cooperation with JCOMM. The Team will be invited to review results of and a plan for the recent workshops, to identify areas where the Team can contribute to the TCP.
  • 7.5 - WMO Disaster Prevention and Mitigation Programme (DPM)
    Under this agenda item, the Team will be presented with the outcomes of the First DPM Coordination Meeting (Geneva, Switzerland, 4 to 6 December 2006) related and/or requesting the involvement of the Team. The Team will be invited to consider this issue and discuss possible interactions between the ETWS and DPM.
  • 7.6 - Users’ community
    The SCG noted that a key activity for the SPA is to draft and publish a proper user community specification of needs within a well-articulated JCOMM Services User Requirement Document (URD), typically based on an assessment of the current capability. The Group agreed that URD can be used to prioritize specific developments and actions within the SPA by identification of gaps in current service provision. In this context, the Group decided to develop a core portfolio on users/applications across SPA Expert Teams. The Team will be invited to consider this issue and to develop a strategy and implementation plan for the preparation of this document.
