This paper examines the question of land surface‐atmosphere interactions in the West
African Sahel and their role in the interannual variability of rainfall. In the Sahel, mean …

Climatic observables are often correlated across long spatial distances, and extreme events,
such as heatwaves or floods, are typically assumed to be related to such teleconnections …

Abstract Purpose of Review Our current understanding of current climate change in the West
African, East African, and Congo Basin monsoon systems is reviewed. The detection of …

An examination of analyses and model simulations is used to show that the African easterly
jet forms over West Africa in summer as a result of strong meridional soil moisture gradients …

The development of tropical depressions within tropical waves over the Atlantic and eastern
Pacific is usually preceded by a" surface low along the wave" as if to suggest a hybrid wave …

Automatic tracking of vorticity centers in European Centre for Medium-Range Weather
Forecasts analyses has been used to develop a 20-yr climatology of African easterly wave …

This study examines selected dynamical factors associated with wet and dry years in the
West African Sahel. The approach is to evaluate the temperature, wind, and moisture fields …

The maintenance of the African easterly jet (AEJ) has been examined using a zonally
symmetric general circulation model with simple parametrizations. It is shown that the AEJ is …
