| Biomass Burning, Southern Africa: A smoke pall dominates this
view of tropical southern Africa, one of the most fire-prone regions
of the world. Numerous fires give rise to regional smoke palls every
dry season. Fires are both natural (started by lightning) and set by
local people to clear woodlands for agricultural fields. This oblique, northwest-looking view from July 2011, at the end of the dry season, shows the extent of the smoke on the African plateau—from central Zimbabwe (image lower left) to northern Malawi more than 1,000 kilometers away (image top right), and in the wide coastal plains of the lower Zambezi River valley of Mozambique (image lower right). Here smoke can be seen blowing inland, channeled up the Zambezi River valley and contributing to the pall on the plateau. The light gray smoke plumes contrast with higher altitude, brighter patchy cloud cover at image lower right. The smoke palls obscure the details on the land surface so that Lake Malawi, one of Africa’s Great Lakes, is barely visible. The same goes for Lake Cahora Bassa, Africa’s fourth largest reservoir, in the Zambezi valley. The sun’s reflection off the surface of Lake Kariba makes it prominent in the view at image left. Kariba is 220 kilometers long and is the world’s largest artificial reservoir by volume. The steep, shadowed, mid-afternoon faces of the Inyanga Mountains on the Mozambique-Zimbabwe border protrude above the smoke layer at image lower left. Solar panels extending from Russian spacecraft docked at the International Space Station are visible at image left. |
