The Influence of Topography on East African October to December Climate: Sensitivity Experiments with RegCM4

Figure 5

Climatology of OND 2 m temperature (in °C) over the period 2000–2008: (a) CRU observed temperature over land, (b) simulated using actual topography (TP100), (c) simulated using topography reduced to 25% (TP25) over 34°E–38°E and 6°S–2°N, and (d) temperature difference [(c) minus (b)] with contours (green) at 3°C interval and the thick (black) contours represent regions over which the temperature difference is zero. The shaded region in (d) is significant at 90% confidence level (shaded area (orange) indicates a region of significant increase in temperature).

(a) CRU TEMP

(b) TEMP TP100

(c) TEMP TP25

(d) TEMP TP25-TP100
