“…First high-resolution RCM studies over West Africa were conducted by Jung and Kunstmann (2007) using the mesoscale meteorological model MM5 (Grell et al, 1994) at 9 km resolution for two time slices, 1991-2000 and 2030-2039, over a comparably small region covering the Volta Basin. They showed an annual mean temperature increase of around 1.3 • C in the Volta region, significantly exceeding the interannual variability, and a mean annual change in precipitation from −20 to +50 %.…”
