Wind Speed

Wind speed data were obtained from the CRU on monthly basis for the period 1948 – 2008. However, only one year; 2008, is plotted in the map below to indicate the pattern. The monthly average wind speed (m/s) is measured at 10m height. The lower part of the basin generally registers higher wind speeds as opposed to the upstream parts of the basin and a clear wave of increase in speed can be seen in the eastern Nile in the months of June – August.
