  3. The Global Observing System of the WWW comprises surface and space-based subsystems; data obtained are transmitted via the Global Tele-communication System to the Global Data-Processing & Forecasting System, where required information and products are produced and sent to the users.

  5. Global Observing System: • Provides observations for all other WMO programmes (including aviation, climate, agriculture, environment, disaster prevention and mitigation) • Operated by National Meteorological Services • Data requirements evolve with technology .

  6. Typical daily coverage of surface observations from land (red) and VOS (blue) stations At present over 10 000 manned and automatic weather stations on land and about 7 000 voluntary observing ships (VOS) at sea provide measurements and observations

  7. Space-based subsystem of the Global Observing System

  8. Tropical Cyclone between Madagascar and Mozambique February 2000 (PUMA)

  9. Global AMDAR Coverage (24-hrs) 4 Nov. 2005

  10. AMDAR Coverage over Africa (24-hrs) 4 Nov. 2005

  11. Scheme of a typical mission of an Argo float A new global observing component in the oceans, the Array for Real-time Ocean Floats (Argo), was introduced; 624 Argo floats were operational in 2003

  12. ARGO Network (January 2005)

  13. Global Telecommunication System: • Organized into three levels: • Global • Regional • National .

  14. Global Data-Processing and Forecasting System: • World Meteorological Centre • Regional Specialized Meteorological Centressuch as for example: • Tropical Cyclone Forecasting • Environmental Emergency Response • National Meteorological Centres .

  15. GDPS Centres running models GLOBAL DATA PROCESSING AND FORECASTING SYSTEM

  16. Application of EPS to Tropical Cyclones - Forecast Guidance – Strike Probability

  17. ERA Concentration Chart

  18. COMMISSION FOR BASIC SYSTEMS • 4 Open Programme Area Groups (OPAGs): • OPAG on Integrated Observing Systems (IOS) • OPAG on Integrated System and Services (ISS) • OPAG of Global Data-Processing and Forecasting Systems (DPFS) • OPAG on Public Weather Services (PWS)
