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

2 2 Training Coverage African Desk NCEP International Desks Week1 Precipitation Probability of exceedance 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 New Website Africa Hazards

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 3

4 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 Concept of NCEP African Desk

5 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 Concept of NCEP African Desk

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

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 21 WRF Modeling Experiments for Africa

22 22 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 WRF EMS – Tanzania Experience Courtesy, P. Mlonganile, TMA

23 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
