Figure 7.10
Angola-Namibia borderlands, August 5, 1997 (locations mapped in Figure 7.9). (A) In this southwest-looking view (NASA photograph NASA5-707-14), the linear east-west border between Angola and Namibia appears prominently across the top of the view, with light tones indicating significantly thinner vegetation on the Namibian side (top left). By contrast, numerous fires appear in the savannas of southern Angola (center) where biomass volume is greater than in Namibia (due to increasing rainfall, high human population densities, and heavier grazing by herd animals on the Namibian side). As indicated by the smoke plumes from individual fires, two wind directions are apparent: in the top half (to the west), winds are southwesterly but in the lower half, winds are from the south-southeast. (B) This north-looking view (NASA photograph NASA5-706-196) shows the dry lakebed of Etosha Pan in northern Namibia (lower left) and many fires in the middle ground. A large, diffuse smoke pall in central Angola with a marked southern boundary stretches across the top of the view. Clouds appear on the horizon, top right, above the smoke layer. This more oblique view complements (A) by showing the same fires in the wider context of regional burning.
