  1. African Training DeskNational Centers for Environmental Predictions Staff Wassila M. Thiaw, Team Leader Vadlamani Kumar Endalkachew Bekele Visitors from NMHSs

  2. African Desk NCEP International Desks • Mission: • Support capacity building at NMHSs in Africa: Professional development training in weather and climate and product exchange • Provide access to NCEP global data and products to promote decision support services in developing countries: Africa, Afghanistan, Central America Training Coverage New Website Africa Hazards Week1 Precipitation Probability of exceedance 2

  3. Overview • African Training Desk established in 1994 – WMO/VCP • Climate Training Desk – Support to WMO/ CLIPS • Weather Training Desk – Support to WMO/ SWFDP • Evolved to focus on DSS:USAID/ FEWSNET & OFDA, USDA Foreign Ag Service, and WMO • Africa, central America, the Caribbean, and Afghanistan • Real time monitoring for humanitarian assistance • Food security • Disaster Risk Reduction • Health Early Warning System

  4. Concept of NCEP African Desk • Provides an opportunity for professional meteorologists in Africa to train at NCEP on operational weather and climate forecasting as part of the US contributions to the WMO VCP • Operates a Climate Desk and a Weather Forecasting Desk. Each desk has the capacity to host 6 meteorologists per year arriving at staggered intervals of 2 months for a total of 12. • NWS provides a 4-month WMO/VCP fellowship • Training is hands-on in an operational setting with an instructor to monitor daily activities and progress

  5. Concept of NCEP African Desk • Objective is to help strengthen the capacities of the NMHSs in weather and climate forecasting • Focus on the operational use and application of numerical model products, climate forecasting and monitoring tools • All fellows must submit a WMO VCP application form to WMO and NWS to be considered

  6. African Training Desk • Partnership • National Weather Service International Activities • WMO • African NMHSs • African regional institutions • Resources • NCEP – base • WMO VCP • USAID

  7. Weather Desk Training Curriculum NAWIPS Use and interpretation of NWP Use of ensembles in operational weather forecasting Write forecast bulletins GIS applications Week-1 forecasts Access and process large data Conduct model verification studies WRF modeling

  21. WRF Modeling Experiments for Africa http://www.cpc.noaa.gov/products/african_desk/wrf_fcst/safrica/

  22. WRF EMS – Tanzania Experience Some output of the wrf model Wrf forecast valid 0600z and 0900z, 17/10/2008 and data time 0000z 16/10/2008 (i.e. the model run was of 0000z of 16/10/2008) The actual observations were as shown on the next slide Courtesy, P. Mlonganile, TMA

  23. Lake Forecast (Nested) data time is 0000z, 18/10/2008. For the forecast starting after 0600z on 18/10/2008 to 0900z, 19/10/1008. Compare with the observations to the next slide Courtesy, P. Mlonganile, TMA

  24. Future Plan • Work with other NOAA agencies to expand the African Training Desk; e.g., aviation weather & marine forecasting • Conduct field visits in the form of workshops for former African Desk trainees • Continue to work with sister agencies within the US government to improve DSS and early warning systems
