Tropical Cyclone Boloetse
| Title |
Tropical Cyclone Boloetse |
| Description |
Tropical Cyclone Boloetse was winding down on February 5, 2006, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on the Aqua [ http://aqua.nasa.gov/ ] satellite captured this image at 10:45 UTC (1:45 p.m. local time). At this time, Boloetse was heading into the southern Indian Ocean after brushing against the southern end of Madagascar. The cyclone had sustained winds of around 120 kilometers per hour (75 miles per hour), classifying it as a Category 1 storm on the Saffir-Simpson scale. This was less intense than the previous day [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13350 ], and forecasters were predicting the storm would continue to diminish in strength as it traveled southeast away from the African coast. Tropical Cyclone Boloetse initially formed in the western Indian Ocean and traveled west, crossing the island of Madagascar as a tropical storm in late January 2006, with moderately strong rains. The storm intensity declined to tropical-depression strength as it crossed the mountainous ridgeline that runs along the eastern shore of Madagascar. However, once the storm system reached the warm waters of the Mozambique Channel, the tropical depression re-organized and built up enough strength to become a tropical cyclone. Once there, the storm reversed direction and headed southeast, taking it across Madagascar once again. It struck a glancing blow over the island's southern tip on February 4, 2006.

Tropical Cyclone Boloetse |
| Description |
Tropical Cyclone Boloetse crossed the island of Madagascar as a tropical storm in late January 2006, with moderately strong rains. The storm intensity declined to tropical-depression strength as it crossed the mountainous ridgeline that runs along the eastern shore of Madagascar. However, once the storm system reached the warm waters of the Mozambique Channel, the tropical depression reorganized and built up enough strength to become a tropical cyclone. The Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite observed Tropical Cyclone Boloetse in the Mozambique Channel on February 3, 2006, at 11:00 UTC (2:00 p.m. local time). At that time, the cyclone was beginning a south and eastward track, and it was predicted to strike a glancing blow along the southwestern corner of Madagascar as it moved back out into the Indian Ocean. The cyclone had sustained winds of around 165 kilometers per hour (105 miles per hour), classifying it as a Category 2 storm on the Saffir-Simpson scale. Storms of this strength typically cause moderate damage to coastal areas with storm surges around 1.5 to 2 meters (4 to 7 feet). Winds are sufficient to damage temporary structures such as trailers and sheds, and remove roofs from some permanent buildings. The large version of the image has a spatial resolution of 250 meters per pixel. Other resolutions are also available from the MODIS Rapid Response website.

Tropical Cyclone Boloetse |
| Description |
Cyclone Boloetse was striking Madagascar for the second time when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on the Terra [ http://terra.nasa.gov/ ] satellite acquired this photo-like image on February 4, 2006, at 07:20 UTC (10:20 a.m. local time). At this time, the cyclone had sustained winds of around 165 kilometers per hour (105 miles per hour), classifying it as a Category 2 storm on the Saffir-Simpson scale. Tropical Cyclone Boloetse first crossed the island of Madagascar as a tropical storm in late January 2006, with moderately strong rains. The storm intensity declined to tropical-depression strength as it crossed the mountainous ridgeline that runs along the eastern shore of Madagascar. When the storm system reached the warm waters of the Mozambique Channel, the tropical depression re-organized and built up enough strength to become a tropical cyclone. Next, the storm reversed direction and headed southeast, taking it across Madagascar once again. It gave a glancing blow over the island's southern tip on February 4, 2006. The large version of the image has a spatial resolution of 250 meters per pixel. Other resolutions are also available from the MODIS Rapid Response website.

Tropical Cyclone Clare
| Title |
Tropical Cyclone Clare |
| Description |
Residents of Western Australia's Pilbara Coast are accustomed to tropical storms, the Pilbara Coast sees more cyclones than any other part of the Australian coastline. Still, Tropical Cyclone Clare strained some nerves in early January 2006. Although the storm was downgraded from a Category 3 to a Category 2, it prompted hundreds of residents to evacuate the area, and downed some power and telephone lines. The Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite took this image of Clare at 10:30 a.m. local time on January 10, 2006. Hurricanes in the Indian Ocean and the Western Pacific Ocean are termed cyclones, and their wind direction depends on whether they are north or south of the equator. In the Southern Hemisphere, cyclone winds blow in a clockwise direction. In this image, Clare stretches hundreds of kilometers across as it moves along the Pilbara Coast. At the time this image was taken, Clare was a well-developed storm system with peak sustained winds of around 100 kilometers (60 miles) per hour. The cyclone's center was about 300 kilometers from Port Hedland, the nearest major city. According to a report from ABC.net.au, the storm had winds as high as 200 kilometers per hour when it struck Dampier, a coastal town approximately 200 kilometers southwest of Port Hedland. The storm also dropped 20 centimeters (almost 8 inches) of rain on Dampier, and forecasters expected more rain for the area. Clare was expected to remain a Category 2 storm as it moved inland. As of the morning of January 10, 2006, however, only minor damage was reported. NASA image created by Jesse Allen, Earth Observatory, using data obtained courtesy of the MODIS Rapid Response team. |
