Mean surface air temperature anomalies for the African continent, 1901 – 1998, expressed with respect to the 1961-1990 average; annual and 4 seasons – DJF, MAR, JJA, SON. The smooth curves result from applying a 10 yr Gaussian filter. (from Hulme et al., 2001).
Observed annual rainfall anomalies for three African regions, 1900-1998, and model-simulated anomalies for 2000-2099. Model anomalies are for 10 model simulations derived from seven DDC GCM experiments; the four HadCM2 simulations are the dashed curves. All anomalies are expressed with respect to observed or model-simulated 1961-1990 average rainfall. Model curves are extracted directly from GCM experiments. Smooth curves result from applying a 20-year Gaussian filter (Hulme et al., 2001).
The survey was led by Mr. Kuria (University of Nairobi) guided by Mr. Isaac N. Kivindyo, Chairman Community Based Organisation (CBO) Sakai Division and accompanied by Cyprian Kaaria Mbaabu Irrigation officer and Mr. Mwoki the District Geologist, Ministry of Water and Irrigation.
