Figure 7.9
Distribution of seasonal forest fires in Africa and Madagascar (shaded areas), as sensed by DMSP satellite sensors in 1986 and 1987. The boundary between the rainforest biome and the savanna woodlands, which are more prone to burning, is shown by a dashed black line. The density of fire distribution wanes southward with the decline in rainfall in the Savanna, and concomitant decline in biomass. Anticyclonic circulation of the atmosphere over southern Africa (gray arrow) transports smoke typically via Angola into the tropical South Atlantic Ocean. Areas and view directions of the four photographs (Figures 7.10 and 7.11) are indicated with thin black lines. (Modified from Cahoon et al., 1992, and Garstang et al., 1996.)
