  1. Public Weather Services Programme Public Warnings Dissemination and CAP Haleh Kootval Chief, Public Weather Services Programme WMO

  2. Forecasts NMHSs Warnings Public Appreciate the weather services PWSP Public Weather Services Programme (PWSP) established in 1994 • Strengthen the capabilities of WMO Membersto meet the needs of the community through provision of comprehensive weather services, with particular emphasis on public safety and welfare, • Foster a better understanding by the publicof the capabilitiesof National Meteorological and Hydrological Services (NMHSs) and how best to use their services”

  3. WMO’s Global Operational Network Global Observing System Global Telecommunication System Global Data Processing And Forecasting System: 3 World Meteorological Centres 40 Regional Specialized Centers NMHSs deliver information and warning services

  4. PWS Dissemination Weather Hazards floods, fire, drought, strong winds, heavy snow etc Services by NMHSs Weather Forecasts, watches, alerts, Warnings Dissemination Methods Websites, TV, Radio, Telephone, RANET Examples of Groups served by NMHSs General Public, isolated communities, Government and civil defence authorities etc.

  5. Dissemination and Presentation • Effective dissemination and presentation: An essential element of and the key to effective PWS • Challenge: To convey warnings, forecasts and other information effectively to general public

  6. WARNINGS - a processthat begins with the production of information about weather and climate and ends with effective loss minimising actions • Warnings must beproduced • Warning message must betransmitted & received • Information must beunderstood • Information must beconfirmed • Message must bebelieved • Risk must bepersonalised • Decision totake appropriate defensive and preparatoryactions • Resourcesandcapacityfor preparatory action

  7. The Challenge of Public warning • Collaborative actions are necessary to assure that standards-based, all-media, all-hazards public warning becomes an essential infrastructure component available to all societies worldwide • Provide information that iseasily accessible and understandableeverywhere

  8. The Challenge of Public warning • All available communications media should be used (from broadcast down to individuals) to get timely and appropriate warnings for all hazards to everyone who needs them • A standards-based, all-media, all-hazards public warning strategy makes sense now using digital technologies and integrating radio, television, cellular telephone, satellites, Internet-based and other network services

  9. Weather, Climate and HealthExample of All-Hazard warning system • Growing awareness of the linkages between human health and weather and climate • PWS provide information on risks caused by changing weather and climate conditions • Cardiovascular and respiratory • Heat and cold stress • UV radiation • Pollen spread and dust • High Ozon concentration • Spread of typhoid, malaria or cholera

  10. Factors contributing to ineffectual warnings • Plans can go wrong because of: • Forecast accuracy: miscalculating onset time, intensity or impacts • “sole authority” issue in preparing and issuing warnings • Communication and/or dissemination inadequacies • Contradictory information from different sources • Low credibility of NMHS

  11. Dissemination of warnings and Forecasts • Often the challenge is to provide the most cost-effective system(s) within severe funding constraints • Dissemination techniques will depend on the communication infrastructure • Robust and reliable • Back up capability

  12. Dissemination of warnings and Forecasts • Dissemination systems: most critical issue for developing countries • Point-to-Multipoint • Mass media (TV, Radio, Newspapers), • sirens and signals, RANET, NOAA Weather Radio • Man on bicycle

  13. Dissemination of warnings and Forecasts • Point-to-Point: Dedicated Fax, automatic telephone answering • Internet • email • Mobile communication • Strength and weaknesses

  14. Examples of Dissemination Korea (high tech) • Cell Broadcasting Service (CBS) Phone Disaster Notification Broadcasting System • Problem: transmission does not reach high mountain areas in need of warnings for flash flood • Radio Disaster Warning Broadcasting System • TV Disaster Warning Broadcasting System

  15. CBS System of Mobile Telecom Company Base Station Request to CBS message Transmission at disaster area CBS message on mobile phone which is located at broadcasted area NEMA End user (Mobile phone with CBS service function] NEMA Mobile Telecom Company ) 【 CBS Message Transmission flow 】 • CBS (Cell Broadcasting Service) Phone Disaster Notification Broadcasting System (Cont’d) ▣ System Structure and Message Flow 7

  16. 5) TV Disaster Warning Broadcasting System ▣ System Management streamlines 16

  17. Examples of Dissemination • Bangladesh (people intensive) • 33000 Cyclone Volunteers • CPP and Red Cross • BMD sends info to CPP HQ • Information gets to the village-level volunteers through radio • Use bicycles • Distribution to public by megaphones and flags • Problme: Maintenance of megaphones and torches

  18. Examples of Dissemination • Sri Lanka- high tech tsunami warning system using satellites, mobile and fixed wireless phones • Challenge: reach large numbers of local communities and rural areas • Major component of the project is use of CAP

  19. The Severe Weather Information Centre (SWIC) http://severe.worldweather.wmo.int • Established as a centralized source for media access to official tropical cyclone warnings and information issued by NMHSs and RSMCc • Has attracted the participation of WMO Members in all tropical cyclone basis • Currently displaystropical cyclone warningsand information for all tropical cyclone basins • Observationson heavy rain/snowfrom all WMO Members are displayed • New page displaying the occurrences ofthunderstormswas also added. • Ultimate goal: to develop SWIC into a Multi-hazard Information and Resource Centre

  20. Visualizing Weather Warnings • Meteoalarm

  21. CAP and PWSConclusions • Existing warning systems are mix of different technologies and procedures • CAP will allow consistent warning message disseminated simultaneously over many different warning systems, thus increasing warning effectiveness • Possibility of use of CAP in SWIC and Meteoalarm for public warnings
