Abstract

Strong interactions and feedbacks between surface processes and deep convection occur in the Sahel. They take place over a wide range of scales. They are found to enhance surfaceatmosphere energy exchanges during the monsoon and to generate a large variability of surface sensible and latent heat fluxes in time and space.A positive feedback is observed between this variability, or more accurately soil moisture heterogeneities, and the frequency of initiation of convective systems. This feedback operates at fine scale, on the order of a few tens of kilometres. The underlying mechanisms and their modelling are discussed.
