Floods in East Africa
| Title |
Floods in East Africa |
| Description |
Kenya gets most of its rainfall in two doses: a long rainy season that runs from March or April through July or August, and a short rainy season that starts in September or October and usually tapers off in December. As if trying to make up for lack of rain during the 2005 short rainy season, [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17250 ]which failed entirely, the rainy season that started in October 2006 proved to be unusually heavy. Some locations in Kenya received as much as 200 millimeters more rain than average in October. The heavy rain fell on drought-baked ground, triggering extensive flooding in northern Kenya. The East Africa Standard, [ http://allafrica.com/stories/200610280016.html ] a Nairobi newspaper, reported on October 28 that 10 people had died in the flooding and more than 75,000 were made homeless. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image of flooding in northern Kenya on October 30, 2006. Aquamarine, sediment-laden flood water runs through the Laga Bogal and Laga Bor river channels and spreads across the surrounding landscape in places. The Lorian Swamp, in the lower-right corner of the image, appeared dry on October 14, when the lower image was captured. By October 30, water flowed through the swamp. The rain has also spurred plant growth. The arid landscape assumed a green tint in the two weeks that passed between October 14 and October 30. In these false-color images, made with both infrared and visible light, vegetation is bright green, bare or sparsely vegetated ground is tan-pink, and clouds are pale blue and white. In this type of image, water is typically black or dark blue, but sediment has given the water a blue-green color in the top image. Eastern Africa regularly goes through cycles of drought and floods, possibly driven by El Niño. El Niño is a cyclical warming of ocean waters in the central and eastern Pacific that can alter weather patterns around the world. In general, El Niño causes drought in some regions like Indonesia, Australia, and the Philippines, while bringing excess rain to others, including East Africa and the southwestern United States. In September 2006, NASA's JASON satellite recorded a mild El Niño [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17419 ] in the tropical Pacific Ocean. At the same time, drought [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13943 ] was settling in over Australia and heavy rain pounded East Africa.Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?NAfrica_3_07 ] of East Africa are provided by the MODIS Rapid Response Team at NASA Goddard Space Flight Center.

Floods in East Africa |
| Description |
Severe drought early in 2006 followed by widespread flooding [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13795 ] during August crippled Ethiopia. In late October and early November, the disaster continued to develop as heavy rain once again sent the Wabe Shebele River over its banks. The swollen river grew to twice its normal size, inundating towns that line its fertile banks, reported the World Food Program [ http://www.alertnet.org/thenews/newsdesk/WFP/4d4580f3cc2d9d49654e66a8daf84c16.htm ]. More than 60 people died in the floods, and many more were impacted. On November 1, 2006, skies cleared, providing the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite a clear view of the floods in southeastern Ethiopia. The Wabe Shabele spreads several kilometers across its flood plain, its water ranging from inky black to light blue. The scene is shown in infrared-enhanced false color to highlight the presence of water on the ground. In this color combination, made with both visible and infrared light, water is typically black, as it is in the lower reaches of the river in this image. Elsewhere in the scene, however, water is light blue because sediment in the water scatters light. The pale blue color blends with the light green of newly growing plants, making it difficult to tell just how extensive the floods are on the west bank of the river. Other waterways on either side of the Wabe Shabele are also filled with mud-laden, light blue water. The lower image, taken on October 7, shows the Wabe Shabele under normal conditions. Though the river is prone to flooding, the attractiveness of living along its banks is clear from this image. Little vegetation is growing in the arid region except along the river's banks, which are lined in green. Conditions changed by November 1. The same rainfall that caused the floods also spurred plant growth, and the landscape went from a barren tan-pink to verdant green. Lines of high clouds, pale blue and white in this false-color image, are scattered across both images. Like much of East Africa, southeastern Ethiopia goes through a regular cycle of floods and droughts. The cycle is in part driven by El Niño, a cyclical warming of ocean waters in the central and eastern Pacific that can alter weather patterns around the world. In general, El Niño causes drought in some regions, such as Indonesia, Australia, and the Philippines, while bringing excess rain to others, including East Africa and the southwestern United States. In September 2006, NASA's JASON satellite recorded a weak El Niño [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17419 ] in the tropical Pacific Ocean. At the same time, drought [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13943 ], was settling in over Australia, and heavy rain pounded East Africa.
