| Title |
Floods in Northwestern Australia |
| Description |
Tropical Cyclone Monty brought heavy rain to drought-stricken regions of Western Australia. While welcome, the rain pushed the Fortescue River over its banks, cutting off a few small communities and isolated homesteads in the rural area. These false-color Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) images show the Fortescue River on February 24, 2004, before Monty came ashore, and on March 3, just after the cyclone moved across the area. Blue-green streaks in the image taken on March 3 show where water covers the land. The Fortescue River appears particularly flooded near the coast, where a large fan shape has replaced the slender line water running into the Indian Ocean. The high-resolution images provided above are at MODIS' maximum resolution of 250 meters per pixel. Images courtesy Jesse Allen, based on data from the MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC (March 3) and the EOS Data Pool (February 24). |

Floods in Western Australia
| Title |
Floods in Western Australia |
| Description |
The largest flood on record on Australia's Murchison River was expected to peak at the river's mouth on March 16, 2006, reported the Australian Broadcasting Corporation [ http://www.abc.net.au/news/newsitems/200603/s1592969.htm ]. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image on the afternoon of March 16. On the right side of the image, the upper reaches of the Murchison River are clearly flooded with a wide blue band expanding out from the river's normal banks. As it enters Kalbarri National Park, the river winds through deep gorges that prevented it from spreading out. Only when it reaches the coast is the river wide again. A bright blue fan of sediment pours from the mouth of the river where mud-laden flood water is draining into the Indian Ocean. The river overflowed after Cyclone Emma inundated the basin with heavy rain on March 1. The excess water took 15 days to drain to the ocean. The floods near the shore threatened the city of Kalbarri, which sits just south of the river. The floods may also have caused damage to Kalbarri National Park, which is centered around the river and the 80 kilometers of gorges it has cut in the red rock. Even without superimposed borders, the park's southern boundary is clearly evident in this image. To the south of the river, a stark line separates the green park from the tan and pink land outside the park. The park's western border is the Indian Ocean. The park's northern and eastern borders are not visible. The MODIS Rapid Response System provides daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?Australia4/2006075 ] of Western Australia.

Cyclone Jacob
| Title |
Cyclone Jacob |
| Description |
Tropical Cyclone Jacob was in the eastern Indian Ocean off the shore of Western Australia on March 10, 2007. This storm had been moving towards the Pilbara coast of northwestern Australia for several days, coming in from the northeast after forming south of Java several days earlier. This photo-like image of Jacob was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] on the Aqua [ http://aqua.nasa.gov/ ] satellite on March 10, 2007, at 2:10 p.m. local time (06:10 UTC). The storm was a moderate-strength tropical cyclone with an irregular shape and no obvious eyewall (ring of towering clouds) at its center. According to the University of Hawaii's Tropical Storm Information Center, [ http://www.solar.ifa.hawaii.edu/Tropical/ ] Cyclone Jacob has sustained winds of 140 kilometers per hour (90 miles per hour) around the time this image was acquired. Jacob was forecast to come ashore near Port Hedland, not far from where Cyclone George [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14163 ] made landfall days earlier. Jacob was not expected to be nearly as powerful, but it will hinder efforts to recover from George. The high-resolution image provided above is at MODIS' full spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions. [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2007069-0310/Jacob.A2007069.0610 ] You can also download a 250-meter-resolution Cyclone Jacob KMZ file [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Mar2007/Jacob.A2007069.0610.250m.kmz ] for use with Google Earth.

Ocean Blooms in the Wake of Cyclone Willy |
| Description |
As tropical cyclones go, Cyclone Willy didn?t amount to much. With winds hovering around 170 kilometers per hour (100 mph) at its strongest, the storm never made landfall, but instead skirted the western coast of Australia into the southern Indian Ocean. Despite that, Tropical Storm Willy was powerful enough to churn up ocean waters, leaving a trail of cool water and thriving plant life in its wake. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA?s Aqua [ http://aqua.nasa.gov/ ] satellite recorded high chlorophyll concentrations in the cold water wake left by the storm on March 16, 2005. A diagonal strip of cooler water, shown in purple in the right image, corresponds well with the lighter blue path of high chlorophyll concentrations in the left image. The storm?s powerful winds stirred the ocean, bringing cool water and nutrients to the surface. With added nutrients in the sun-drenched surface waters, small ocean plants (phytoplankton) multiply quickly, raising chlorophyll concentrations. The profusion of plant life does not extend beyond the path of the storm, further corroborating the connection between the phytoplankton bloom and cyclone.

Fires in Northwest Australia
| Title |
Fires in Northwest Australia |
| Description |
Scattered fires in Australia's northern Western Australia state and Northern Territories send smoke streaming off in the northwestward-blowing wind. The smoke plumes appear as streaks of gray moving away from the fires, which are marked in red. In the lower center of the image, right on the border between the two states, sits man-made Lake Argyle, the largest freshwater body in the Southern Hemisphere. The lake was created in the early 1970s as part of the Ord River Irrigation Project, which was designed to transform the area around the Ord River into a highly productive agricultural oasis. To the north of Lake Argyle is the Joseph Bonaparte Gulf, which shows clouds of tan and green in its waters. The majority of these clouds are caused by sediment and silt from rivers emptying into the Gulf, though they may also indicate the presence of microscopic marine life. Similar clouds appear off the coast of the Northern Territories (upper right) between the mainland and Melville Island in the Van Diemen Gulf, as well as off the coast of Western Australia. Beyond the Joseph Bonaparte Gulf is the Timor Sea, and in the upper left corner of the image is the eastern edge of the Indian Ocean. This true-color Aqua MODIS image was acquired on April 24, 2003. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at MODIS' maximum spatial resolution of 250 meters.

Fires on Borneo and Sumatra

Fires on Borneo and Sumatra |
| Description |
On August 22, 2004, clouds and smoke swirled over the islands that sit between Australia and Asia, at the crossroads of the Indian Ocean to the west and the Pacific Ocean to the east. Large islands pictured here are Borneo (right), Java (bottom), and Sumatra (left) At top left is the southern tip of mainland Malaysia. In each of these places, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite detected actively burning fires (marked in red). Over the weekend of August 21, the haze in Singapore (at the southern tip of mainland Malaysia), at least some of which was smoke from the fires, was so severe that air traffic was interrupted.

Tropical Cyclone Clare
| Title |
Tropical Cyclone Clare |
| Description |
Tropical Cyclone Clare is a moderately strong storm system in the Indian Ocean off the Australian coast. When the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite observed the cyclone at 06:05 UTC (2:05 p.m. local time) on January 9, 2006, it was a well-developed system with peak sustained winds of around 100 kilometers per hour (60 miles per hour). The cyclone (the local term for a hurricane or typhoon) was about 200 kilometers offshore from Port Hedland in Western Australia, the nearest major city. NASA image created by Jesse Allen, Earth Observatory, using data obtained courtesy of the MODIS Rapid Response team. |
