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 Carina |
| Description |
Tropical Cyclone Carina appears as a tightly wound spiral in the Indian Ocean in this satellite view of the storm, obtained by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Aqua satellite on February 27, 2006. Carina had become an organized storm system four days earlier, and built rapidly into a powerful cyclone. By the time MODIS obtained this observation of Carina, peak winds were blowing at 175 kilometers per hour (110 miles per hour). However, the tropical cyclone was moving into the southern Indian Ocean well away from the nearest land, even the very remote Cocos Islands several hundred kilometers east.

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.

Tropical Cyclone Emma
| Title |
Tropical Cyclone Emma |
| Description |
Tropical Cyclone Emma formed as a low-intensity storm system and built to cyclone strength only briefly. But Emma's brief cyclone status belied its size and rainfall. The Moderate Resolution Imaging Spectrometer (MODIS) instrument on the Aqua observed the storm system as it was losing strength, and hence its tropical cyclone status, on February 28, 2006, at 5:55 UTC (1:55 p.m. local time). At this time, the cyclone had peak winds of roughly 55 kilometers per hour (35 miles per hour). As the image shows, the storm system covered an enormous area, extending over almost the entire extent of Western Australia. With it came heavy rain and substantial flooding to the Pilbara Region, the northwestern corner of Western Australia, where the storm system came ashore.

Tropical Cyclone Favio
| Title |
Tropical Cyclone Favio |
| Description |
Tropical Cyclone Favio formed in the western Indian Ocean about 1,200 kilometers from Madagascar on February 14, 2007. It gradually moved southwest, passing well offshore of Reunion and Mauritius Islands. By February 20, it was just off the southern shore of Madagascar as a well-formed, mature storm. While the storm system had largely skirted around populated areas to that point, forecasters were concerned about its behavior as it entered the warmer waters of the Mozambique Channel. The storm was forecast to reach Category Four [ http://www.nhc.noaa.gov/aboutsshs.shtml ] strength before coming ashore and tracking inland through Zimbabwe and Zambia, bringing heavy rains to already flooded areas. [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14115 ] This photo-like image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] on the Aqua [ http://aqua.nasa.gov/ ] satellite on February 20, 2007, at 2:15 p.m. local time (11:15 UTC). The storm was turning north around the southern end of Madagscar, headed for the Mozambique Channel. Favio had the recognizable shape of a southern-hemisphere tropical cyclone, with spiral arms showing its clockwise rotation. The spiral arms are well-defined and tightly wound. A distinct eye at the center of the storm is only partially filled with clouds (a "partially closed" eye). These are all signs of a well-developed and powerful storm, consistent with the cyclone's strength. According to the University of Hawaii's Tropical Storm Information Center, [ http:/NaturalHazards/natural_hazards_v2.php3 www.solar.ifa.hawaii.edu/Tropical/ ] Favio had steady winds of around 160 kilometers per hour (100 miles per hour) around the time MODIS made this observation. 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.

Tropical Cyclone Favio
| Title |
Tropical Cyclone Favio |
| Description |
Tropical Cyclone Favio came ashore on the coast of Mozambique on the morning of February 22, 2007. At the time it crossed the shoreline, Favio had lost some strength from its peak the previous day, but still had extremely powerful winds. The cyclone continued to weaken as it passed over land, becoming a tropical depression. As of 8:00 a.m. local time (0600 UTC), winds were down to 60 kilometers per hour (38 miles per hour), according to the South African Weather Service. [ http://www.weathersa.co.za/ ] This photo-like image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] on the Aqua [ http://aqua.nasa.gov/ ] satellite on February 23, 2007, at 1:45 p.m. local time (11:45 UTC), as the tropical depression was crossing into Zimbabwe. The storm still has a distinct balled-up form left over from its cyclone state the previous day, but once over land, the strong circular eye and powerful eyewall storms typical of a cylone were gone. As it traveled farther inland towards the Zambezi River valley, the storm brought heavy rains to Zimbabwe. This region had already suffered from heavy rains associated with the onset of the monsoon, and severe flooding along the Zambezi River [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14115 ] in mid-February killed dozens of people and forced more than a hundred thousand people to evacuate, according to reports [ http://www.reliefweb.int/rw/RWB.NSF/db900SID/LSGZ-6YMDSC?OpenDocument ] from the International Federation of Red Cross and Red Crescent Societies posted online by ReliefWeb. [ http://www.reliefweb.int/rw/dbc.nsf/doc100?OpenForm ] There had been widespread additional evacuations ahead of Cyclone Favio's arrival.

Tropical Cyclone George
| Title |
Tropical Cyclone George |
| Description |
Tropical Cyclone George came ashore on the remote Pilbara coast of Western Australia on the evening of March 8, 2007, as a very powerful Category 4 storm, [ http://www.nhc.noaa.gov/aboutsshs.shtml ] with wind speeds as high as 275 kilometers per hour (170 miles per hour). According to the online version of the Sydney Morning Herald, the storm was responsible for at least two deaths [ http://www.smh.com.au/news/national/cyclone-george-kills-two-jacob-advances/2007/03/09/1173166991751.html ] and many serious injuries as of March 10. This photo-like image of George was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] on the Aqua [ http://aqua.nasa.gov/ ] satellite on March 9, 2007, at 1:25 p.m. local time (05:25 UTC). The storm was still a strong tropical cyclone with a circular shape and distinct eye at its center, despite the fact that the storm had been traveling over land for nearly a day when the image was captured. According to the University of Hawaii's Tropical Storm Information Center, [ http://www.solar.ifa.hawaii.edu/Tropical/ ] Cyclone George had sustained winds of 120 kilometers per hour (75 miles per hour) near the time this image was acquired. George was the worst storm to hit the area in 30 years, and the government declared the region a disaster area. Rescue and recovery efforts were expected to be complicated by the arrival of Cyclone Jacob. As a Category 2 storm, Jacob was smaller and weaker, and it was not expected to wreak the same kind of destruction as George.

Tropical Cyclone Glenda
| Title |
Tropical Cyclone Glenda |
| Description |
Tropical Cyclone Glenda formed off the northwestern coast of Australia on March 27, 2006. The storm quickly built into a powerful and well-defined cyclone during the next day. Powerful winds have whipped up surf along the coastline of Western Australia's Pilbara region, and the storm has brought heavy rains to the islands off the Kimberly coast. As of March 30, 2006, the storm had lost some power and was ranked as a powerful Category 4 storm, after having peaked the previous day. This photo-like image was acquired by the Moderate Resolution Imaging Spectrometer (MODIS) on the Aqua satellite on March 30, 2006, at 2:10 p.m. local time (06:10 UTC). It shows Cyclone Glenda as a well-developed storm, sitting just off the coastline about 300 kilometers (185 miles) from Port Hedland. Clouds from the storm covered most of the northwest coastline of Western Australia. Sustained, peak winds in the storm system were roughly 195 kilometers per hour (120 miles per hour) at this time. The storm's spiraling clouds appear as a nearly solid white disk, and the faint bluish eye is poised just off the coastline. Observations as of 8:00 p.m. Australian Western Standard Time on March 30 were that the storm was crossing the coast near Onslow. The town was bearing the brunt of the worst winds near the cyclone's center. The Australian Bureau of Meteorology predicted that wind speeds could gust as high as 235 kilometers per hour (140 miles per hour) as the storm continued to come ashore. Residents in coastal communities who were not yet evacuated were directed to stay put, as the severe winds would make attempting to move extremely dangerous. Australian news services are comparing Glenda to the famous and destructive cyclones Larry and Tracy. Larry struck the Queensland coast just two weeks before Glenda, while Tracy remains imprinted on Australia's memory as the storm that flattened Darwin on Christmas Eve 1974. Glenda is large and more powerful than either of these storms, but striking in a much more sparsely populated area.

Tropical Cyclone Gonu
| Title |
Tropical Cyclone Gonu |
| Description |
MODIS Rapid Response Team, [ http://rapidfire.sci.gsfc.nasa.gov ] Goddard Space Flight Center., You might expect to see a storm with near-perfect symmetry and a well-defined eye hovering over the warm waters of the Caribbean or in the South Pacific, but Tropical Cyclone Gonu showed up in an unusual place. On June 4, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image, Tropical Cyclone Gonu was approaching the northeastern shore of Oman, a region better known for hot desert conditions. Though rare, cyclones like Gonu are not unheard of in the northern Indian Ocean basin. Most cyclones that form in the region form over the Bay of Bengal, east of India. Those that take shape over the Arabian Sea, west of the Indian peninsula, tend to be small and fizzle out before coming ashore. Cyclone Gonu is a rare exception. As of June 4, 2007, the powerful storm had reached a dangerous Category 4 [ http://www.nhc.noaa.gov/aboutsshs.shtml ] status, and it was forecast to graze Oman's northeastern shore, following the Gulf of Oman. According to storm statistics maintained on Unisys Weather, [ http://weather.unisys.com/hurricane/ ] the last storm of this size to form over the Arabian Sea was Cyclone 01A, which tracked northwest along the coast of India between May 21 and May 28, 2001. Unlike Gonu's forecasted track, Cyclone 01A's path never brought it ashore. MODIS acquired this photo-like image at 12:00 p.m. local time (9:00 UTC), a few hours after the Joint Typhoon Warning Center [ https://metocph.nmci.navy.mil/jtwc.php ] estimated Gonu's sustained winds to be over 240 kilometers per hour (145 miles per hour). The satellite image confirms that Gonu was a super-powerful cyclone. The storm has the hallmark tightly wound arms that spiral around a well-defined, circular eye. The eye is surrounded by a clear wall of towering clouds that cast shadows on the surrounding clouds. Called hot towers, [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17662 ] these clouds are a sign of the powerful uplift that feeds the storm. The symmetrical spirals, clear eye, and towering clouds are all features regularly seen in satellite images of other particularly powerful cyclones, which are also known as typhoons or hurricanes when they form in other parts of the world. 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.

Tropical Cyclone Gonu
| Title |
Tropical Cyclone Gonu |
| Description |
A cyclonic storm like Tropical Cyclone Gonu might not seem an odd sight until you consider that Gonu occurred in the Gulf of Oman and made landfall in Iran, a nation not known for cyclones. The most recent storm of Gonu's magnitude hit the neighboring Sultanate of Oman was in 1977, according to the news service AlJazerra.net [ http://english.aljazeera.net/English/ ] (English language).Given the rarity of these storms in the area, many shore facilities were never constructed to deal with the severe winds, strong rains, and high storm surge. At 12:55 p.m. local time (09:55 UTC) on June 7, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image, Tropical Cyclone Gonu was crossing the Gulf of Oman and heading northward towards the Iranian coast. By this time, the powerful storm had lost considerable power and was considered a mere powerful tropical storm. Sustained winds were measured at 60 kilometers per hour (40 miles per hour) according to the University of Hawaii's Tropical Storm Information Center. [ http://www.solar.ifa.hawaii.edu/Tropical/ ] The satellite image shows Gonu bringing rain to both Oman and Iran as it heads north to the Iranian coastline. Because such storms are virtually unheard of in this part of the world, authorities have treated the storm with considerable caution: government offices in Oman and most private businesses declared a holiday from June 5 until June 9. They recommended people stay in their homes as much as possible and stock basic supplies and emergency needs, according to Middle East Online. [ http://www.middle-east-online.com ] Residents in low-lying coastal areas in southeastern Iran were also being evacuated, while the fishing fleet in neighboring Pakistan was ordered to stay in as waves battered the shores. Gonu, however, did not appear poised to reach the Straits of Hormuz, and oil shipping from the Persian Gulf had not been significantly disrupted as of June 6, according to a number of news services.

Tropical Cyclone Jaya
| Title |
Tropical Cyclone Jaya |
| Description |
Tropical Cyclone Jaya came ashore in northern Madagascar in the morning of April 2, 2007 at around 11:00 a.m. local time (08:00 UTC). The storm formed in the Indian Ocean on March 30 and traveled westward toward Madagascar as predicted. What was not predicted, however, was its explosive growth in power from a strong tropical storm to a powerful Category 3 cyclone [ http://www.nhc.noaa.gov/aboutsshs.shtml ] in just 36 hours, according to figures provided by the University of Hawaii's Tropical Storm Information Center. [ http://www.solar.ifa.hawaii.edu/Tropical/tropical.html ]Fortunately, the intensification took place while Jaya was still far from Madagascar. This photo-like image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] on the Aqua [ http://aqua.nasa.gov/ ] satellite on April 3, 2007, at 1:15 p.m. local time (10:15 UTC). The storm was a tropical cyclone with a circular shape, but no distinct eye at its center. According to the University of Hawaii's Tropical Storm Information Center, [ http://www.solar.ifa.hawaii.edu/Tropical/ ] Cyclone Jaya's sustained winds had fallen in strength to roughly 125 kilometers per hour (80 mph) at the time this image was acquired. When the storm made landfall on Madagascar, sustained winds were around 150 kilometers per hour (90 miles per hour), a marked change from 200 km/hr (125 mph) just twelve hours earlier. While much weakened, Jaya remained a powerful storm. Furthermore, it struck the northern part of Madagascar where a series of other cyclones have also come ashore in recent months. Forecasters were concerned that Jaya might reform after crossing the island and head inland into Mozambique, where residents are recovering from floods caused by recent heavy rains. 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.

Tropical Cyclone Kate |
| Description |
Tropical Cyclone Kate swirls in the Torres Strait between Australia's Cape York Peninsula and the island of New Guinea in this satellite view of the storm, obtained by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Aqua satellite on February 23, 2006. Kate was the second tropical cyclone in 2006 to form off the coast of Queensland. It was not a particularly powerful system when MODIS obtained this view, with peak winds around 80 kilometers per hour (50 miles per hour). However, because it was located so far offshore, there was little observed data from ground stations and radar instruments, which was making predictions of the storm's path and future intensity a challenge, according to the Tropical Cyclone Warning Centre.

Tropical Cyclone Larry
| Title |
Tropical Cyclone Larry |
| Description |
Tropical Cyclone Larry formed off the northeastern coast of Australia on March 18, 2006. The cyclone gained power rapidly and came ashore on Queensland's eastern coastline, where it hammered beaches with heavy surf, tore roofs off buildings, and perhaps most destructively, flattened trees in banana plantations over a wide area. The Melbourne Age reported estimates that as much as 80 percent of the Australian banana crop has been destroyed. Since many trees have been uprooted, it may be many years before the banana industry recovers. When the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite observed the storm at 3:05 p.m. Australian Eastern Daylight Savings Time (04:05 UTC) on March 21, 2006, Larry had been downgraded to a tropical depression several hours before, and wind speeds had dropped to below 60 kilometers per hour (40 miles per hour). But while Larry's winds had dropped down to much less destructive levels, the storm system was still bringing significant rainfall in the upper reaches of the Darling River basin, and it retained the classical spiral form of a tropical storm even as it continued to become less organized.

Tropical Cyclone Vaianu
| Title |
Tropical Cyclone Vaianu |
| Description |
Tropical Cyclone Vaianu was moving south of the Tonga Islands on February 15, 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 1:35 UTC (1:35 p.m. local time). At this time, Vaianu was heading south past the chain of islands, having knocked out electricity in many areas in the preceeding two days, as well as flattening trees and crops. Flooding in low-lying areas shut down the Tonga capital, Nuku'alofa, for two days. When Aqua observed the cyclone, it had peak sustained winds of around 80 kilometers per hour (50 miles per hour), and it was gradually losing strength. Although it was weakening, it maintained a distinct, spiral cloud structure. The only island visible is this image is Tongatapu, in the northwestern (upper left) corner, just at the end of a spiral-cloud arm. Most of the island is under thin cloud cover, but the pale blue of shallow water and coral reefs stand out from the deep blue of the Pacific Ocean around them. Tongatapu is the largest island in the Tonga Island chain, and the Tonga capital, Nuku'alofa is on this island.

Tropical Cyclone Vaianu
| Title |
Tropical Cyclone Vaianu |
| Description |
Tropical Cyclone Vaianu was threading its way through the Tonga Islands on February 13, 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 1:45 UTC (1:45 p.m. local time). At this time, Vaianu was heading south through the chain of islands, knocking out electricity in many areas, as well as flattening crops such as bananas, mangos, and breadfruit trees. Flooding in low-lying areas shut down the capital, Nuku'alofa, for two days as stores barricaded their doors and windows to protect them from battering winds. The cyclone had peak sustained winds of around 140 kilometers per hour (85 miles per hour), but the storm center where these peak winds were observed was well away from the Tonga and Fiji Islands. The large green island just visible under clouds in the northwestern corner (top left) of this image is Viti Levu, one of two large islands in the Fiji Islands. Vanua Levu is barely visible to the north and east of Viti Levu. The Tonga Islands all lie to the east of Fiji and are covered under the spiralling cloud formation of Cyclone Vaianu.

Tropical Cyclone Wati
| Title |
Tropical Cyclone Wati |
| Description |
Tropical Cyclone Wati formed northeast of New Caledonia on March 19, 2006. The cyclone gained power gradually and had been heading towards the coast of Australia along a track similar to the very destructive Cyclone Larry, which came ashore in Queensland at the same time Wati was building power. However, forecasts as of March 22 projected that while Wati would continue to gain strength, it would turn sharply south and east, staying well away from the Australian mainland and New Calendonia. When the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite observed the storm at 3:05 p.m. Australian Eastern Daylight Savings Time (04:05 UTC) on March 21, 2006, Tropical Cyclone Wati was continuing to slowly build power and size. When MODIS made this observation, the storm had peak winds of around 150 kilometers per hour (90 miles per hour), and forecasts at the time called for it to continue to gather power for at least another day. It was predicted to slowly weaken as it headed south and traveled over cooler water. In this image, the scattered and unorganized remnants of Tropical Cyclone Larry can still be seen over Queensland, well east of Cyclone Wati.
