African Climate Workshop

Climate Dynamics of Tropical Africa:
present understanding and future directions
Sponsored by Ernst Cloos Memorial Funds

November 15 & 16, 2012
Mason Hall Auditorium, Homewood Campus

This one and a half day invitational event was devoted to presentations, panel responses, and full group discussions designed to promote cross-fertilization between research programs and to inspire future collaborations. Topics included: global and regional drivers of African climate variability, utilizing and enhancing the modern observational record, applications of climate dynamics to paleoclimate studies, and the challenge of projecting future climate conditions.


The first day of talks and discussions in the African Climate Workshop was followed by a poster session and reception in Olin Hall and then a dinner for the speakers at The Dizz a local restaurant.  The lively poster session provided a chance for participants to present and discuss their work in detail.  E&PS students and postdocs were well represented.  Chloe Gao (senior E&PS undergraduate major), Alexi Russell (2nd year graduate student), Fisseha Berhane (2nd year graduate student), Hamada Badr (2nd year graduate student), Amin Dezfuli (PIM Postdoctoral Fellow) and Zelalem Bedaso (Blaustein Postdoctoral Fellow) all presented posters on their research related to African Climate.
