SWFDP - Eastern Africa Regional Training Workshop on Severe Weather Forecasting and Warning Services

This workshop focuses on improving severe weather forecasting and warning services in Eastern Africa through the SWFDP program. It includes discussions on operational weather forecasting, basic systems, severe weather warnings, and daily public forecasts. Participants will gain knowledge on using NWP and EPS to enhance early warnings.

  1. WMO World Meteorological OrganizationWorking together in weather, climate and water SWFDP - Eastern Africa Regional Training Workshop on Severe Weather Forecasting and Warning Services Bujumbura, Burundi, 11 - 22 November 2013 WMO GDPFS Programme – SWFDP - Eastern Africa Peter Chen, Alice Soares WMO Secretariat, DPFS Division, WDS (pchen@wmo.int) WMO; WDS/DPFS www.wmo.int

  2. Outline • Operational weather forecasting - the WMO’s World Weather Watch (WWW) and its Global Data-Processing and Forecasting System (GDPFS) • SWFDP concepts and projects • SWFDP – Eastern Africa

  3. « Basic Systems » ?? • severe weather warnings • Episodic • risks, impacts daily public forecasts - routine

  4. The World Weather Watch System –An operational infrastructure • The World Weather Watch System combines: • Observing systems, GOS => WIGOS, • Telecommunication, data and information exchange network, WIS (GTS), and • Production - data-processing and forecasting systems (in GDPFS) • Operated by Members, coordinated through the WMO Secretariat • To make available meteorological and related geophysical information needed by Members for providing efficient Meteorological SERVICES

  5. The Global Data-Processing and Forecasting System (GDPFS) of the WWW • Makes available to WMO Members weather and climate analyses, forecasts and predictions to enable them to provide … high-quality predictions and forecasts, warning and information services …. • Applications of NWP outputs • GDPFS supports many WMO programmes and relevant programmes of other International Organizations, e.g. ICAO, IAEA, etc. • (see: “Manual on the GDPFS”- WMO-No. 485)

  6. World Weather Watch & Basic Systems S&T into operational services <= Integrated Observing System (WWW/WIGOS) <= Global Telecom & Data Management (WWW/WIS) <= Global Data-Processing and Forecasting System (WWW/GDPFS) <= National Meteorological Services providing services to public and users (PWS)

  7. GDPFS Centres + National Meteorological Centres

  8. Weather Forecasting Daily forecasts and weather information are available on: Open Internet Private enterprises Academic institutions Weather as news (e.g. focus on disasters) WMO Operational weather forecasting WMO’s GDPFS Centres Numerous advanced NWP Centres Authoritative, reliable and quality assured sources of information (objective verification), sustainable and replicable

  9. GDPFS Centres • GDPFS Centres are NMCs at NMHSs • 24/7/365 operationally supported infrastructure (e.g. at NMCs, RSMCs, GPCs) • Highly automated and robust production with backup, and recovery system • Meteorological expertise • Regional structure (e.g. multi-national and regional centres) for collaboration, harmonization, operational advantage

  10. GDPFS • Severe Weather Forecasting Demonstration Project • Cascading forecasting process: • Global products centres => RSMCs => National Centres • Collaborative Exploitation of Ensemble System Products • Enhancing availability, use and applications, in probabilistic forecasting, e.g. for severe weather; • Multi-model ensemble applications • Long-range Forecasting (seasonal forecasts) (see http://www.wmolc.org) • Global Producing Centres => Regional => National Centres • Nuclear Environmental Emergency Response Arrangements • Maintain operational commitment of designated RSMCs – in coordination with International Organizations (IAEA, ICAO, CTBTO, UN-OCHA, WHO)

  11. Numerical simulations of the atmosphere “In general, the public is not aware that our daily weather forecasts start out as initial value problems on the major national weather services supercomputers. “Numerical weather prediction provides the basic guidance for weather forecasting beyond the first few hours.” • Eugenia Kalnay (2003) • From: “Atmospheric Modeling, Data Assimilation and predictability” Cambridge University Press, 2003, 5th printing 2009

  12. The Challenge: mitigating the growing technological gap in weather forecasting ? Dramatic developments in weather forecasting science over the past two decades – advances in monitoring and NWP and Ensemble Prediction Systems (EPS) leading to improved alerting of weather hazards, at increased lead-times of warnings Most of NMHSs saw little progress due to limited budgets, etc. increasing gap in application of advanced technology (NWP, EPS) in early warnings WMO SWFDP attempts to close this gap by increasing availability, and developing capacity to use existing NWP and EPS 12

  13. Why an SWFDP? • WMO developed the SWFDP to improve severe weather forecasting and warning services in NMHSs where sophisticated NWP/EPS outputs are not currently used • Linking Forecasting (GDPFS) with Service Delivery (PWS), and engaging regions of few countries • Introducing new forecasting products into the operational environment, supported by annual training and evaluation & verification activities, to improve warning services • Pave the way for promising R&D outputs (e.g. TIGGE-GIFS) in transition to operations • Principal focus: hazardous weather conditions and weather-related hazards

  14. Severe Weather Forecasting Demonstration Project (SWFDP) WMO Vision for improving severe weather forecasting and warning services in developing countries“NMHSs in developing countries are able to implement and maintain reliable and effective routine forecasting and severe weather warning programmes through enhanced use of NWP products and delivery of timely and authoritative forecasts and early warnings, thereby contributing to reducing the risk of disasters from natural hazards.” (World Meteorological Congress, 2007 and 2011) WMO Strategic Priorities • Disaster Risk Reduction • Capacity Development • Climate change adaptation

  15. Severe Weather Forecasting Demonstration Project (SWFDP) WMO SWFDP Main Goals • Improve Severe Weather Forecasting • Improve lead-time of Warnings • Improve interaction of NMHSs with users: media, disaster management, civil protection authorities SWFDP Regional Subprojects • Southern Africa (ongoing; 16 countries; RSMC Pretoria, RSMC La Réunion) • Southwest Pacific Islands (ongoing; 9 Island States; RSMC Wellington, RSMC Fiji) • Eastern Africa (ongoing, 7 countries; RSMC Nairobi, RFSC Dar) • Southeast Asia (in development, 5 countries) • Bay of Bengal (in development, 6 countries)

  20. SWFDP – improving forecasts and warnings • Severe weather: heavy rain, strong winds, forecast range: up to day-5 (increased lead-time) • Forecasting (GDPFS) and warning services (PWS) • High-impact focus (flash-flooding, wind damage, near-shore damaging waves, storm surges, etc.), and application areas (e.g. TCP, AgM, HWR, MMO, etc) • Forecast verification • Climate change adaptation
