Building AMMA To reach AMMA aims, need to coordinate -Science (Challenge: disciplines, scales) -Implementation (Obs, Model,..) -Data archive and sharing -Funding issues

  3. AIMS • To improve our understanding of the WAM and its influence on the • physical, chemical & biological environment regionally and globally. (2)To provide the underpinning science that relates variability of the WAM to issues of health, water resources, food security & demography for West African nations and defining and implementing relevant monitoring & prediction strategies. (3)To ensure that the multidisciplinary research carried out in AMMA is effectively integrated with prediction & decision making activity.

  7. WG1: West African Monsoon and Global Climate Co-leaders:Arona Diedhiou (IRD, Niger), Serge Janicot (LOCEAN, France) Peter Lamb (Univ. Oklahoma, US) 2-way interactions between West African Monsoon & the rest of the globe to determine the variability of the WAM and its global impacts to understand and to predict the multi-scale variability of the aspects of global climate linked to the WAM Including: Aerosol and chemistry activities Modelling activity

  8. WG1: West African Monsoon and Global Climate Observed and modeled rainfall (with labels for onset and retreat) for Niamey based on area-average of 50 gauges and model simulated rainfall ( Lebel et al, 2000).

  9. WG1: West African Monsoon and Global Climate Dominant pattern of precipitation error associated with dominant pattern of SST prediction error based on persistent SST anomalies (Goddard & Mason ,Climate Dynamics, 2002) Coupled model systematic error in equatorial SST simulation – note systematic error in east-west gradient in the tropical Atlantic

  12. WG3a: Land-surface-atmosphere feedbacks Co-leaders:Jan Polcher (LMD, France); Chris Taylor (CEH, UK) To provide increased knowledge & understanding of the feedbacks between the continental surface & the atmosphere  to bring together the various process studies (land and atmosphere) in order to better understand the coupling at regional and mesoscale

  13. WG3a: Land-surface-atmosphere feedbacks Koster et al, 2004

  14. WG3b: Ocean-surface-atmosphere feedbacks Co-leaders:Bernard Bourles To provide increased knowledge & understanding of the feedbacks between the ocean surface & the atmosphere  to bring together the various process studies (ocean and atmosphere) in order to better understand the coupling at regional scales

  15. WG4: Prediction of climate impacts Co-leaders:Abou Amani (AGHRYMET, Niger), Andy Morse (Univ. Liverpool, UK), Madeleine Thompson (IRI, US) One of the 3 major aims of AMMA: To provide the underpinning science that relates climate variability to issues of health, water resources, food security & demography for West African nations and defining relevant monitoring and prediction strategies.

  16. WG4: Prediction of climate impacts Example: Meningitis epidemics in Mali Semaine de démarrage de l’épidémie January Semaine du maximum du cycle saisonnier (hiver) (Position du FIT la plus basse en latitude) Prediction  Alert Systems

  17. WG5: High impact weather prediction and predictability CORE Membership: E. Afiesimama (NIMET), S. Jones (Un. Karlsuhe, Ger), D. Parsons (NCAR, US), F.Rabier (Meteo-France),C. Thorncroft (SUNY, US), Z. Toth (NCEP, US) To improve our knowledge & understanding of high impact weather over Africa, including its impact on the tropical Atlantic and Europe. Key timescale of interest is 1-15 days Can we predict dry/wet spells 15-days in advance? Do such dry spells influence downstream tropical cyclone activity?

  18. International Coordination & Implementation Group Co-chairs: Thierry Lebel (IRD-Niger) & Doug Parker (Un Leeds UK) ICIG is responsible for implementation of the AMMA field program

  25. AMMA human issues & a scientific challenge AMMA a challenge for African Research AMMA a programme mobilizing the African & international Communities

  26. KEY ISSUES • Funding for Africans: AMMA-International is currently working to mobilize funds to support African participation in AMMA. This includes participation in AMMA meetings (workshops, conferences, working group meetings etc). It also includes support for AMMA science and proposals provided already by African scientists. Can the JSC help/advise? • AMMA – an Integrated Regional Study? AMMA-International would like to discuss the possibility of it becoming an IRS and to see in particular if this would help to mobilize resources for African participation in AMMA. • African representation on the JSC: We will recommend an African candidate to join the JSC (as requested) after we have had further discussions with the coordinators of AMMA-Africa. We will hope to provide this recommendation by the end of May.
