West Africa Monsoon & its Modelling Session

West African Monsoon and its Modeling

AGU Atmospheric Section A072

(Cosponsors: Biogeosciences, Global Environmental Change, Hydrology, Nonlinear Geophysics, and Ocean Sciences Sections)

The West African Monsoon (WAM), a major component of the global climate system, possesses one of the strongest long-term (multi-decadal) signals in the 20th century associated with the Sahel drought.

Despite the progress in WAM studies, better understanding and proper simulation of WAM at different scales and WAM association with external forcing (ocean, land, aerosols) remains a daunting task. This session focus on (1) intercomparison and evaluating skills of global and regional climate models in simulating the WAM rainfall and relevant processes; and identification of major challenges, weaknesses, and uncertainties that still remain in modeling the WAM; results from WAMME, AMMA, ALMIP, and other intercomparison are welcome, (2) representation of  major WAM characteristics and attribution to possible mechanisms at different time scales, and (3) studies using data from various sources for model evaluation and improvement.  Please submit the abstract before 6 August, 2013.   AGU has very strict rule on this deadline.   No exception.
