| Title |
Cyclone Harvey Moves Over Australia |
| Description |
Cyclone Harvey hit the northern coast Australia on Monday, February 7, 2005, near the border between the Northern Territory and Queensland along the Gulf of Carpentaria with wind gusts of up to 220 kph (132 mph). The storm was rated as a Category 3 Cyclone at landfall by the Bureau of Meteorology's Tropical Cyclone Warning Center. In November of 1997, the Tropical Rainfall Measuring Mission or TRMM satellite was launched to measure rainfall over the global Tropics. Armed with both passive and active sensors including the first and only precipitation radar in space, TRMM as has proven itself to be a valuable tool for examining tropical cyclones. TRMM was able to capture these unique images of Cyclone Harvey as it traversed the Gulf of Carpentaria and struck the coast of Australia. The first image, top left, was taken at 08:52 UTC (6:22 pm Australian CST) on February 6, 2005, just as Harvey was becoming better organized in the central Gulf of Carpentaria. The image shows the horizontal distribution of rain rates (top down view) by the TRMM satellite. Rain rates in the center swath are from the TRMM Precipitation Radar (PR), while rain rates in the outer swath are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). The center of Harvey falls within the TMI swath in this image. Only light (blue areas) to occasional moderate (green areas) rain intensity is present, and most of the rain is located west of the center of Harvey. Little or no banding is visible in the rainfield indicating that the system is still in the early stages of development. At the time of this image, Harvey was rated as a Category 1 Cyclone by the Bureau of Meteorology?s Tropical Cyclone Warning Center indicating peak wind gusts of less than 125 kph (78 mph)--equivalent to a tropical storm. The next image, top left, was taken at 07:57 UTC (5:27 pm Australian CST) on February 7, just as Harvey was hitting the coast. While the rain field still appears to be skewed to the west of the storm, the center is now surrounded by several areas of very intense rainfall (dark red areas) on the order of 2 inches per hour. Tropical cyclones rely on the heat that is released when water vapor condenses into cloud droplets, known as latent heating, to drive their circulation. These smaller cloud droplets eventually form into larger raindrops that are easier to observe. This heating is most effective at powering the storm when it is released near the center of circulation. The final image is a vertical cross section looking east through the center of Harvey taken by the PR. It shows that the area of intense rain in the previous image is associated with what scientists call a ?chimney cloud,? a deep, convective tower that extends high into the atmosphere well above the freezing level. Chimney clouds have been associated with the intensification of tropical cyclones. This particular chimney cloud extends up to an, altitude of 20 km. It can be detected by the PR as precipitation-sized particles are lofted up high by updrafts within the cloud. So far Harvey has resulted in only minor flooding in eastern parts of the Northern Territory.TRMM [ http://trmm.gsfc.nasa.gov/ ] is a joint mission between NASA and the Japanese space agency JAXA.

Cyclone Ingrid
| Title |
Cyclone Ingrid |
| Description |
It is extremely rare for a powerful tropical cyclone to make landfall, weaken significantly, then later re-intensify back into a powerful storm again, but Cyclone Ingrid did just that. After crossing Queensland's Cape York Peninsula on the 10th of March 2005, Cyclone Ingrid appeared to have all but dissipated (please see our related TRMM story). On March 11, 2005, a greatly-weakened Ingrid re-emerged over open water in the Gulf of Carpentaria. In a phenomenal re-birth, Ingrid rapidly re-intensified, going from tropical storm strength back to a Category 4 cyclone with maximum sustained winds estimated at 120 knots (138 mph) by the Joint Typhoon Warning Center in the span of just 12 hours. The Tropical Rainfall Measuring Mission satellite captured the top image of a rejuvenated Ingrid just off of the northeastern tip of Australia's Northern Territory at 16:05 UTC on March 11 (2:05 a.m. on March 12, Australian CST). The image shows the horizontal distribution of rain intensity (top down view) as viewed by the TRMM satellite. Rain rates in the center swath are from the TRMM Precipitation Radar (PR), while rain rates in the outer swath are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). Ingrid's center appears well-defined with a tight, symmetrical eye. Heavy rain rates (red areas) are embedded in the eyewall, and good banding is evident in the arcs of moderate rain intensity (green arcs) surrounding the eye. Ingrid continued to move due west, paralleling the coast and remaining over water. This also allowed the storm to strengthen even further, becoming a Category 5 Super Cyclone on the evening of March 12 (local time). During the night and early morning of the following day, March 13 (local time), Ingrid hammered Croker Island with reports of recorded winds reaching 320 kph (198 mph), devastating the island. Fortunately, there were no reported deaths or injuries as residents took shelter. Continuing westward, Ingrid next crossed northern portions of the Cobourg Peninsula followed by Melville and Bathurst Islands north of Darwin. The center image, taken by TRMM at 15:50 UTC on March 13 (1:50 am on March 14, Australian CST) shows Ingrid right over the northern tip of Melville Island. At the time, Ingrid was a Category 3 storm with maximum sustained winds estimated at 100 knots (115 mph). An eye is not readily apparent with the storm's circulation having been disrupted by its passage over the Cobourg Peninsula and Melville Island. However, a large area of intense rain (red area) still exists near the center with prominent banding still visible in the surrounding rain field. After passing over the northern tip of Bathurst Island, Ingrid entered the Timor Sea and was once more over open water. The storm now took a more southerly course heading southwest and began to strengthen yet again. On March 14, remarkably, Ingrid reached Category 4 intensity for the 3rd time, with winds estimated at 115 knots (132 mph). The final image was taken at 05:45 UTC (3:45 pm Australian CST) on March 15. Although the storm's center only falls within the TMI swath, a complete eye is clearly visible once again (green circle) with localized areas of heavy rain (red areas) embedded in the eyewall. Near the time of this image, Ingrid's sustained winds were estimated at 130 knots (150 mph). Ingrid finally came ashore on the northern coastline of Kimberley in Western Australia on the night of March 15 (local time) near Faraway Bay.TRMM [ http://trmm.gsfc.nasa.gov/ ] is a joint mission between NASA and the Japanese space agency JAXA.

Cyclone Ingrid

Cyclone Ingrid |
| Description |
Cyclone Ingrid crossed the eastern shoreline of Queensland, Australia just south of the town of Lockhart River on the morning of March 10, 2005, (local time) as a powerful Category 4 storm. The Australian Bureau of Meteorology's Cyclone Warning Centre in Queensland estimated the storm's wind gusts to be as strong as 240 kilometers per hour (149 mph). Fortunately, damage was not widespread because of the compact size of the storm and the sparse population in the impacted region. Five people did drown, however, when their boat capsized in heavy seas south of Papua New Guinea. This series of images shows Cyclone Ingrid as it developed in the Coral Sea and moved over Queensland. The images were acquired by the Tropical Rainfall Measuring Mission (TRMM) satellite, which, since its launch in the fall of 1997, has provided unprecedented and valuable information on tropical cyclones around the tropics. With an active radar and a passive microwave sensor, TRMM can peer into the heart of these storms and relay important details on storm structure and location to forecasters. The upper left image was taken at 17:31 UTC on March 6, as Ingrid was intensifying over the Coral Sea. The image shows the horizontal distribution of rain intensity (top down view) as viewed by the TRMM satellite. Rain rates in the center swath are from the TRMM Precipitation Radar (PR), while rain rates in the outer swath are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). The center of Ingrid falls within the TMI swath in this image. TRMM shows that Ingrid already has a well-defined eye outlined by an area of moderate rain intensity (green areas) with evidence of good banding surrounding the eye (green arcs). At the time of this image, Ingrid was the equivalent of a minimal typhoon with maximum sustained winds estimated at 65 knots (75 mph) by the Joint Typhoon Warning Center. The upper right image was taken on March 7, at 08:29 UTC. The PR shows that there are heavy rain rates (red areas) in the southwestern part of the eyewall and in a rainband just south of the center. The eye is small and symmetrical. In addition, Ingrid itself is shown to be a small storm. These rather small, compact cyclones are often referred to as "midget" cyclones. Ingrid, however, was now an intense cyclone with maximum sustained winds estimated at 120 knots (138 mph), equivalent to a Category 4 typhoon. As Ingrid continued to move east towards Australia it strengthened further before starting to weaken as it neared the coast and made landfall on the March 10. The lower left image shows Ingrid on March 9, just before the storm's center moved ashore. The lower right image was taken at 07:11 UTC (5:11 pm Australian CST) on March 10. After having crossed to the western side of the Cape York Peninsula, Ingrid weakened substantially. There is no longer any evidence of an eye and no signs of organization in the rain field., Ingrid is expected to re-emerge over the warm waters of the Gulf of Carpentaria and head for the Northern Territory.TRMM [ http://trmm.gsfc.nasa.gov/ ] is a joint mission between NASA and the Japanese space agency JAXA.

Record Rains Hit Melbourne,

Record Rains Hit Melbourne, Australia |
| Description |
Melbourne, Australia set an all time record rainfall for a 24-hour period on the evening of the February 2 and morning of February 3, 2005. With a rainfall total of 120 mm (4.7 inches), more rain fell in that 24-hour period than any other day since records began in 1856. The previous record was 108 mm. An low-pressure center that intensified over Victoria was responsible for generating the storms, which spread gusty winds and heavy downpours across southeast Queensland, New South Wales, Victoria and Tasmania. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center monitors rainfall over the global Tropics. MPA rainfall totals for the February 1-3, 2005 are shown for southeastern Australia. Between roughly 40 and 75 millimeters of rain (green and yellow areas) are shown over the coastal range just north of Melbourne with locally heavier amounts of up to 4 inches (isolated red areas). The darker red areas along the east coast of New South Wales indicate areas over 100 millimeters of rainfall, and more than 75 millimeters inches of rain is shown by the orange area over the northeast tip of Tasmania.

Melbourne, Australia set an all time record rainfall for a 24-hour period on the evening of the February 2 and morning of February 3, 2005. With a rainfall total of 120 mm (4.7 inches), more rain fell in that 24-hour period than any other day since records began in 1856. The previous record was 108 mm. An low-pressure center that intensified over Victoria was responsible for generating the storms, which spread gusty winds and heavy downpours across southeast Queensland, New South Wales, Victoria and Tasmania. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center monitors rainfall over the global Tropics. MPA rainfall totals for the February 1-3, 2005 are shown for southeastern Australia. Between roughly 40 and 75 millimeters of rain (green and yellow areas) are shown over the coastal range just north of Melbourne with locally heavier amounts of up to 4 inches (isolated red areas). The darker red areas along the east coast of New South Wales indicate areas over 100 millimeters of rainfall, and more than 75 millimeters inches of rain is shown by the orange area over the northeast tip of Tasmania. TRMM is a joint mission between NASA and the Japanese space agency JAXA. Image produced by Hal Pierce (SSAI/NASA GSFC) and caption by Steve Lang (SSAI/NASA GSFC). |
