West Africa is known to be particularly vulnerable to climate change due to high climate
variability, high reliance on rain-fed agriculture, and limited economic and institutional …

The West African Sahel is well known for the severe droughts that ravaged the region in the
1970s and 1980s. Meteorological research on the region has flourished during the last …

The common explanation for the progression of the rainy season over Africa is the seasonal
excursion of the ITCZ. The ITCZ paradigm stems from a time when tropical rainfall was …

In the future, the Sahara and Sahelian regions could experience more rainfall than today as
a result of climate change. Wetter periods, termed African humid periods, occurred in the …

Variation in the seasonal cycle of African rainfall is of key importance for agriculture. Here an
objective method of determining the timing of onset and cessation is, for the first time …

We review the major conceptual models of atmospheric moisture transport, which describe
the link between evaporation from the ocean and precipitation over the continents. We begin …

The assessment of sources of moisture is key to the understanding of the hydrological cycle
at different time scales, because it enables the establishment of source-sink relationships …

We examine the ability of an ensemble of 10 Regional Climate Models (RCMs), driven by
ERA-Interim reanalysis, in skillfully reproducing key features of present-day precipitation and …

This study evaluates the ability of different gridded rainfall datasets to plausibly represent the
spatiotemporal patterns of multiple hydrological processes (ie streamflow, actual …

Previous studies found that Central Equatorial Africa (CEA) has experienced a long-term
drying trend over the past two decades. To further evaluate this finding, we investigate …
