Himalayas Exaggerated (Draft) |
| Abstract |
Satellite photographs (from Terra-MODIS) and computer-generated models help visualize Bangladesh's place in the world. Located in South Asia, it is virtually surrounded by India and the Bay of Bengal to the south. But in many ways, the country's fate is dominated by the world's highest mountain range looming to the north-the Himalayas. |

Haze along the Himalaya Fron
…
| Title |
Haze along the Himalaya Front Range |
| Description |
A river of haze follows the course of the Ganges River in northern India, flowing eastward along the base of the towering, snow-capped Himalaya Mountains (upper right) before turning south over Bangladesh and then spreading out in gray streamers over the Bay of Bengal in the Indian Ocean (lower right). Although the pollution comes from human activities,?agricultural fires, home heating sources that rely on wood, kerosene, or dung, and industrial and vehicle emissions?it lingers because of topography and atmospheric circulation patterns. In the winter phase of the Indian Ocean Monsoon, winds typically blow seaward, which carries the large, thick "brown cloud" of pollution far out over the ocean. Recently, NASA scientists announced that the visible particles of soot that give the polluted air its name aren't the only component of the brown cloud that the atmosphere transports over long distances. The plume also contains ozone, which is beneficial to humans when it is located way above the Earth in the stratosphere, but harmful when it is located closer to the Earth in the troposphere. Ozone spreads even farther away from the original source than the soot particles. Convection over the ocean sucks the ozone high into the air where it enters wider-scale atmospheric circulation patterns. These patterns spread the ozone westward across the Indian Ocean, Africa, and onward to the Atlantic Ocean. Along the way, the ozone from the Asian brown cloud gets mixed together with ozone from agricultural fires in Africa, as well as with ozone from the stratosphere which occasionally gets mixed down to lower altitudes. The long-range transport of ozone from these sources explains why such high levels of tropospheric ozone are observed in the air over the South Atlantic Ocean, far from the source of the emissions.

Smog over the Bay of Bengal

Smog over the Bay of Bengal |
| Description |
Against the arcing backdrop of the Himalaya Mountains (top of image), rivers of grayish haze follow the courses of the Ganges River and its tributaries (left) and the Brahmaputra River (right) on February 1, 2006. The plumes appear to combine like their watery counterparts and flow out together over the Bay of Bengal past the Mouths of the Ganges, the multi-pronged delta of the river along the Bangladesh coast. This image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite. Scientists studying the cloud of haze that frequently lingers over parts of Asia from Pakistan to China and even the Indian and Pacific Oceans have called the pollution the "Asian Brown Cloud." The mix of aerosols (tiny particles suspended in the air) includes smoke from agricultural and home heating and cooking fires, vehicle exhaust, and industrial emissions. In addition to the respiratory problems the persistent haze can cause, it also appears to hinder crops by blocking sunlight and could be altering regional weather.

Flooding in Eastern India
| Title |
Flooding in Eastern India |
| Description |
India's annual monsoon triggered widespread flooding throughout the country in early July 2007. In West Bengal, ABC News [ http://www.abc.net.au/news/stories/2007/07/08/1972766.htm ] reported, nearly a million people were stranded by flooding. Every major river in the East Indian state was swollen from torrential rain and releases from too-full reservoirs, ABC added. As of July 10, at least 187 people had died and 7 million had been affected by flooding across India, said Reuters. [ http://www.reuters.com/article/homepageCrisis/idUSDEL267798._CH_.2400 ] This image shows extensive flooding in West Bengal (top) and northern Orissa (lower left) as seen by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flying on NASA's Terra [ http://terra.nasa.gov/ ] satellite on July 9, 2007. The lower image was taken on May 31, before the monsoon rains started. In this type of image, water is typically black, as seen in the Bay of Bengal. However, the water is heavily laden with mud in the flooded landscape, so its coloring is light blue. The extensive floods cut between the channels of the Ganges River, which flow into the Bay of Bengal in the center of the image, and extend southwest along the coast. Additional flooding is visible in the large image, which shows a broader area. Clouds, which appear light blue and white in this image made from infrared and visible light, cover the floods in Bangladesh to the east. In addition to causing floods, the monsoon rains have brought new life to eastern India. The landscape has gone from the tan-pink of bare earth to the bright green that indicates plant cover. You can download a 250-meter-resolution KMZ file of the flooding [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Jul2007/eindia_tmo_2007190.kmz ] and comparison imagery from May 31, suitable for use with Google Earth.

Flooding in Eastern India
| Title |
Flooding in Eastern India |
| Description |
Abutting the southern front of the snow-clad Himalaya Mountains, the broad, flat Ganges Plain is laced with rivers that transport glacial melt to the Bay of Bengal or the Arabian Sea. Not surprisingly, these rivers lead something of a Dr. JekyllMr. Hyde existence: during the dry winter, the rivers are small and sedate, their headwaters largely locked in ice. In the summer, temperatures in the mountains climb, melting mountain-top snow and fueling the Asian monsoon, and the rivers swell into roaring giants. Not every year is the same howeverthe monsoon may be wetter in a particular year or winter snows might be greater, leading to more snowmeltand 2007 numbered among the more extreme flood years. Heavy rain throughout July pushed the Ganges and its many tributaries over their banks, submerging large tracts of land in northeastern India. As of August 3, nearly 20 million people had been displaced in India, Bangladesh, and Nepal, and 125 had died in India, reported BBC News. [ http://news.bbc.co.uk/2/hi/south_asia/6927389.stm ] Among the most severely hit states was India's northeastern Bihar state. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flying on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image of flooding on the Ganges and its tributaries on August 3, 2007. The lower image, captured by Aqua MODIS on June 4, 2007, shows the plain before the summer monsoon and snowmelt swelled the rivers. In these images (made with a combination of infrared and visible light), water is black or dark blue. Water takes on a brighter shade of blue when tinged with sediment. Clouds, pale blue and white, are scattered over the flooded region, which is bright green with vegetation. Sparsely vegetated areas or bare earth in the lower image are rose-tinted tan. On August 3, the Ganges, Gandak, and Kosi Rivers were so swollen that it was hard to see exactly where the rivers normally flow. The tributaries that feed the Kosi River, not even visible on June 4, have combined in a vast web of water-covered land. The light blue area under the clouds in the lower left corner of the image is probably water-soaked earth, not standing water. Though destructive, seasonal flooding in the Ganges River system blankets the plain with fertile alluvial soil, making it productive farmland. Because the plain is so fertile, it is one of the most densely populated regions on Earth.Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_India3/2007215 ] of northeastern India are available from the MODIS Rapid Response System in both false color, as shown here, and photo-like true color.

Ganges River Delta, Banglade
…
| Title |
Ganges River Delta, Bangladesh, India |
| Description |
The Ganges River Delta is the largest inter-tidal delta in the world. With its extensive mangrove mud flats, swamp vegetation and sand dunes, it is characteristic of many tropical and subtropical coasts. As seen in this photograph, the tributaries and distributaries of the Ganges and Brahmaputra Rivers deposit huge amounts of silt and clay that create a shifting maze of waterways and islands in the Bay of Bengal. |
