Hurricane Dennis
| Title |
Hurricane Dennis |
| Abstract |
The formation of Hurricane Dennis on July 5 made that the earliest date on record that four named storms formed in the Atlantic basin. Dennis proved to be a powerful and destructive storm in the Caribbean Sea and the Gulf of Mexico. It crossed over Cuba on July 8 and 9, leaving at least 10 dead, and caused additional deaths in Haiti. After re-emerging over open water, Dennis re-strengthened into a dangerous Category 4 hurricane with top wind speeds of 233 kilometers per hour (145 mph). The storm passed within 90 kilometers (55 miles) of Pensacola, Florida, and hit land about 80 kilometers (50 miles) east of where Hurricane Ivan struck in September, 2004. A large storm surge of more than 10 feet was created in certain areas, and many homes and businesses in low-lying areas were flooded. |

| Abstract |
During the summer of 2005, the Earth-Sun Exploration Division of NASA/Goddard Space Flight Center(GSFC) brought together resources from NASA to study tropical cyclones. The MAP '05 Project, so named for its affiliation with NASA's Modeling, Analysis, and Prediction (MAP) program, applies NASA's advanced satellite remote sensing technologies and earth system modeling capabilities to improve our understanding of tropical cyclones that develop in and move across the Atlantic basin. MAP '05 implemented the most recent version of the NASA/Goddard Earth Observing System (GEOS) fifth-generation global atmospheric model and the Gridpoint Statistical Interpolation (GSI) analysis system under development as a collaboration between NOAA's National Centers for Environmental Prediction (NCEP) and the Global Modeling and Assimilation Office (GMAO) at GSFC. This animation displays MAP '05's wind analysis data for every 6 hour interval from August 23 through August 31, 2005. |

TRMM Satellite and TMI Swath
| Title |
TRMM Satellite and TMI Swath |
| Abstract |
The Tropical Rainfall Measuring Mission (TRMM) satellite was launched on November 27, 1997, as a joint mission of NASA and the Japan Aerospace Exploration Agency, JAXA. TRMM has five Earth-observing instruments on board and circles the Earth every 92 minutes in an equatorial orbit between 35 degrees north and south latitude so that those instruments can measure precipitation in the tropics. One of the instuments, TMI, observes five frequencies of microwave emissions in a 780-kilometer wide swath along the orbit in order to measure the amount of rain and ice in the atmosphere. This animation shows the TRMM satellite orbiting for one day, August 27, 2005, showing a set of TRMM measurements at a frequency of 85.5 GHz. In this frequency band, atmospheric ice crystals scatter microwaves and so areas with ice crystals appear colder than areas with no ice. Both Hurricane Katrina, just to the west of Florida in the Gulf of Mexico, and Typhoon Talim, in the westerm Pacific between Japan and New Guinea, show up as bright swirling patterns. This measurement is just one of the TMI measurements that go into calculating the total instantaneous rainfall in the tropics. |

Hurricane Dennis |
| Description |
After striking Cuba on July 8, 2005, Hurricane Dennis had lost strength from passing over land. However in the Gulf of Mexico, it recovered and strengthened into a powerful Category 4 storm once again during the early morning hours of July 9th, with maximum sustained winds back up to 125 knots (144 mph). Fortunately for residents in the Florida panhandle, Dennis weakened just before making landfall due to the storm's passage over slightly cooler water. Dennis made landfall around 3:30 p.m. CDT on July 10th just east of Pensacola, Florida, as a Category 3 storm with maximum sustained winds of 120 mph. This image shows Hurricane Dennis at 22:41 UTC (5:31 p.m. CDT) on July 10th, just after the storm had made landfall. The eye is already open to the south as hurricanes tend to quickly weaken over land, and almost all of the rain is occurring north and east of the center (green and blue areas). Rain rates in the center of the swath are from the TRMM Precipitation Radar (PR), the only radar measuring precipitation from space. 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). This image shows a rejuvenated Dennis with maximum sustained winds back up to 90 knots (104 mph). The eye is well formed and contains intense 2-inch-per-hour rain rates (dark red area) in the northeastern part of the eyewall, an indication that strong heating is occurring in the core and is reinvigorating the system. The Tropical Rainfall Measuring Mission (TRMM) satellite has been monitoring the progress of Dennis since it formed in the eastern Caribbean. Launched in 1997 to measure rainfall over the Tropics, TRMM continues to prove itself as an excellent platform for observing tropical cyclones.

Hurricane Katrina Erodes the U.S. Gulf Coast |
| Description |
Gulf Coast cities weren't the only land surfaces to take a beating from Hurricane Katrina in August 2005. Barrier islands stretching from Texas to Florida were also scoured by the wind and waves of the powerful storm. Permanent changes to the shape and elevation of Timbalier Island and its northeastern companions are visible in this pair of infrared-enhanced images from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite. Timbalier Island, the largest island pictured here, sits at the interface between the Gulf of Mexico (south) and Terrebonne Bay (north) along the Louisiana coast southwest of New Orleans. Compared to the image from 2000 (bottom), a large swath of bright sand dominates the eastern side of Timbalier Island in the September 13 image, having either been piled there or exposed by waves and storm surge. To the east-northeast, two small, curving islands have disappeared completely, while farther north, the fierce seas turned two small slots in a barrier island into a single large gap.

Hurricane Rita
| Title |
Hurricane Rita |
| Description |
A tropical depression formed in the Bahamas on September 17, 2005. Once it was organized enough to have winds of over 62 kilometers per hour (39 miles per hour), it was classified as a tropical storm and given the name Rita, becoming the 17th named storm system of the 2005 hurricane season. With the season not yet over, 2005 is already the 5th most active storm season since naming records were started in 1851. According to the National Hurricane Center, 21 tropical storms formed in 1933, 19 developed in 1995 and 1887, and 18 formed in 1969. Rita is also the earliest "R" named storm in a season. Rita crossed the threshold to tropical storm status around 5:00 p.m. (local time) on September 18, 2005. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image of Rita roughly fives hours earlier at 11:40 a.m. while the storm was still an organizing tropical depression. The classical spiral structure of a hurricane is not yet fully formed, nor is there a well-organized eye of the storm, but these nascent features of the developing system are apparent already. Forecasters are particularly concerned about Rita as it is projected to pass through the Florida Key Islands as it reaches hurricane strength. The storm track projections as of September 19 have it crossing the Gulf of Mexico to make landfall in the general vicinity of southern Texas, but forecasting hurricanes several days in advance is still an uncertain science and there are fears that Rita could turn in the Gulf and head into areas recently battered by Katrina.

Hurricane Rita |
| Description |
After the immense devastation brought by Hurricane Katrina, all eyes were on Hurricane Rita as it passed over the Florida Keys and the Gulf of Mexico. Rita formed from a tropical disturbance east of the Turks and Caicos Islands into a depression (TD #18) on September 17, 2005. The system moved west through the Caicos and strengthened into a tropical storm on the 18th before entering into the southern Bahamas. Category 2 Hurricane Rita was passing between the Florida Keys and Cuba when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image at 2:35 p.m. Eastern time on September 20, 2005. At the time, Rita had peak sustained winds of 160 kilometers per hour (100 miles per hour), with hurricane-strength winds extending well away from the storm's center, including settlements in the Key Islands and in Cuba's capital, Havana. The large image provided above has a resolution of 250 meters per pixel. The image is available in additional resolutions from the MODIS Rapid Response Team.

Hurricane Rita
| Title |
Hurricane Rita |
| Description |
The onslaught from the 2005 hurricane season continued with the arrival of Hurricane Rita, the second Category 5 storm to threaten the Gulf of Mexico in less than a month. As it was passing south of the Florida Keys on September 20, 2005, Hurricane Rita was in the process of slowly intensifying from a Category 1 storm into a Category 2 storm. However, upon entering the Gulf of Mexico, Rita tapped into a deep layer of very warm water located in the southeast part of the Gulf associated with the Loop Current. This allowed Rita to undergo a process known as rapid deepening, which transformed it into a powerful Category 5 hurricane with the 3rd lowest air pressure ever recorded in an Atlantic Basin storm. Fortunately, as Rita moved across the Gulf away from the loop current, it slowly began to weaken. The Tropical Rainfall Measuring Mission (TRMM) satellite observed Rita at 13:45 UTC (9:45 am EDT) on September 23, 2005 as the hurricane was passing south of the central Louisiana coast. The center of the storm lies within the TRMM Microwave Imager (TMI) swath. Areas of very heavy rain (dark red areas) associated with an outer rainband are approaching the the Louisiana coast. The eyewall is not as symmetrical as in earlier observations, one sign of a weakening storm. Rita, however, was still strong with sustained winds of 220 kilometers per hour (140 miles per hour) when this image was taken. The TRMM satellite is one of many being used to monitor hurricanes and typhoons. Launched in November of 1997 to measure rainfall over the tropics, TRMM has proven to be a valuable platform for observing tropical cyclones and can provide unique images and information on these storms. TRMM is a joint mission between NASA and the Japanese space agency JAXA. Images produced by Hal Pierce (SSAI/NASA GSFC) and captioned by Steve Lang (SSAI/NASA GSFC). |

Rita formed from a tropical disturbance east of the Turks and Caicos Islands into a depression (TD #18) on September 17, 2005. The system moved west through the Caicos and strengthened into a tropical storm on the 18th before entering into the southern Bahamas. This image shows the horizontal distribution of rain intensity within Rita measured by the Tropical Rainfall Measuring Mission's (TRMM) sensors. Rain rates in the center part of the swath are from the TRMM Precipitation Radar (PR), the only radar capable of measuring precipitation from space. The PR can provide fine-resolution rainfall data and details on the vertical structure of the storm. 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 image was taken at 08:28 UTC (4:28 a.m. EDT) on September 20 as Rita was passing through the Florida Straits. Although the center of Rita does not fall within the PR swath, it is obvious from TRMM that Rita is becoming better organized. A ragged eye is present, surrounded by areas of moderate rain (green areas) with good banding in the outer rainbands, all signs that the storm's circulation is improving. Rita was still a tropical storm at the time of this image, with sustained winds of 110 kilometers per hour (70 miles per hour). By early afternoon the same day, Rita would become a Category 2 hurricane as it passed south of the Florida Keys and headed for the Gulf of Mexico. The TRMM satellite is one of a number of satellites being used to monitor Hurricane Rita and storms like it. Launched in November of 1997 to measure rainfall over the tropics, TRMM has proven itself to be a valuable platform for observing tropical cyclones, which include hurricanes and typhoons.

Hurricane Wilma
| Title |
Hurricane Wilma |
| Description |
Hurricane Wilma was still gathering strength when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite took this image at 11:55 a.m. Eastern Daylight Time, on October 18, 2005. At that time, Wilma was rapidly building in power and size. While lacking the classic, tightly wound spiral of a well-developed hurricane, Wilma was becoming a force to be reckoned with. Less than 24 hours later, Hurricane Wilma exploded in strength to the very top of the wind strength scale as a Category 5 hurricane. When this image was taken, Wilma's sustained winds were 120 kilometers per hour (75 miles per hour). Just 18 hours later, they were 280 km/hr (175 mph)! At that point, Wilma became the most powerful storm in terms of both wind speeds and air pressure ever measured in an Atlantic hurricane. Wilma also set records by becoming the 21st named storm of the 2005 Atlantic Hurricane season. This made 2005 the most active hurricane season on record, tied with 1933. Wilma's projected course on October 19 had the storm entering the Gulf of Mexico between western Cuba and the Yucatan Peninsula, then heading eastward across southern Florida.

| Description |
Hurricane Wilma remained a powerful Category 4 storm when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite took this image at 12:25 p.m. Eastern Daylight Time, on Friday, October 21, 2005. Two days earlier, Wilma had surged from tropical storm to Category 5 hurricane in record time. Winds around the eyewall of the storm were raging at 280 kilometers per hour (175 miles per hour). National Oceanographic and Atmospheric Administration (NOAA) aircraft had also measured a record-low air pressure of 882 millibars in the center of Hurricane Wilma, making it the most intense hurricane ever observed in the Atlantic basin. Since then, Wilma has lost some of her history-making strength, but this is little comfort to those in her path. In this image, the storm eye is about to cross Cozumel, a small island just off the Yucatan Peninsula coast. Winds were peaking at 230 km/hr (145 mph) as the eyewall passed over the island, and hurricane-strength winds extended for 130 kilometers (85 miles) from the storm's center. As of Friday afternoon, Wilma was projected to continue into the Gulf of Mexico, bringing powerful winds and heavy rain to both western Cuba and the Yucatan Peninsula before turning toward southern Florida. Florida residents have already begun to prepare for the storm's arrival.

Hurricane Wilma
| Title |
Hurricane Wilma |
| Description |
After setting the all-time record for the lowest recorded pressure in the Atlantic basin as a powerful Category 5 hurricane in the western Caribbean, Hurricane Wilma weakened to a still-powerful Category 4 storm. On October 21, 2005, Wilma slowly crossed over Cozumel as a strong Category 4 hurricane with sustained winds reported at up to 230 kilometers per hour (144 miles per hour) by the National Hurricane Center (NHC). The center of Wilma then drifted over the far northeastern tip of the Yucatan Peninsula delivering torrential rains and strong winds. Before being caught up in the westerlies, Wilma stalled out over the Yucatan, resulting in a sustained period of heavy rain and flooding. The rainfall was observed by the Tropical Rainfall Measuring Mission (TRMM) satellite. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center provides estimates of rainfall over the global tropics. MPA rainfall totals due solely to Wilma are shown for October 17-25, 2005, with storm symbols marking the storm track. Rainfall totals on the order of 300 to 400 millimeters (12 to 16 inches: darker red areas) are located over the northeastern part of the Yucatan Peninsula. After drifting over the Yucatan and weakening to a Category 2 storm, Wilma was picked up by a mid-latitude weather system known as a "trough." The storm accelerated off to the northeast across the southeastern Gulf of Mexico toward Florida, where it made landfall on the morning of October 24 just south of Marco Island. Wilma raced across southern Florida with winds in excess of 160 km/hr (100 mph) in just 6 hours. This quick transit kept rainfall totals down. MPA rainfall amounts over Florida are generally 150 mm (6 inches or less: green areas). TRMM is a joint mission between NASA and the Japanese space agency, JAXA.

Hurricane Wilma
| Title |
Hurricane Wilma |
| Description |
When Wilma became a named tropical storm on October 17, 2005, it tied a record dating back to 1933 for the most named storms in a season. When Wilma became a hurricane on October 18, it tied the record dating back to 1969 for the most hurricanes in a season. However, when Wilma shot from a tropical storm to a Category 5 hurricane on the morning of October 19, it broke the all-time record for the lowest pressure ever measured in the Atlantic Basin. A hurricane's central pressure is an indicator of its intensity—the lower the pressure, the more intense the storm. The Tropical Rainfall Measuring Mission (TRMM) satellite observed Wilma approaching the Yucatan Peninsula at 00:55 UTC on October 21, 2005 (8:55 pm EDT October 20, 2005). This 3-D perspective of Wilma shows a cut-away view of the eye, with cloud height on the top right side of the storm and rain rates in the lower left side of the storm. TRMM measures the cloud height with radar, which detects the location of precipitation (and therefore clouds). In this image, clouds tower over 10 kilometers above the ocean around the eye. The deep ring of red at the base of the eye shows that heavy rain is falling in the same area. TRMM reveals that Wilma had a well-defined, closed inner eye of intense rain surrounded by larger concentric rings of more moderate rain. (The concentric rings are easier to see in the version of the image that does not include the 3-D cloud height overlay, available here.) The sharply curved features in the rain field surrounding the inner eye are the mark of well-developed, intense circulation. At the time of the image, Wilma was a Category 4 storm with maximum sustained winds reported at 240 kilometers per hour (150 miles per hour) by the National Hurricane Center. At its height, Wilma had sustained winds of 280 km/hr (175 mph). At the time these images were taken, Wilma was drifting very slowly to the northwest towards Cozumel, Mexico. The storm was expected to enter the Gulf of Mexico as a weaker hurricane before making landfall along the west coast of Florida. The TRMM satellite is one of many satellites monitoring hurricanes and typhoons. Launched in November of 1997 to measure rainfall over the Tropics, TRMM has a number of instruments that are valuable for observing tropical cyclones. In these images, rain rates in the central portion of the swath are from the TRMM Precipitation Radar (PR). Rain rates in the outer swath are from the TRMM Microwave Imager (TMI).

In these images, rain rates in the central portion of the swath are from the TRMM Precipitation Radar (PR). 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).TRMM [ http://trmm.gsfc.nasa.gov/ ] is a joint mission between NASA and the Japanese space agency JAXA.

Hurricane Wilma Floods Flori
…
| Title |
Hurricane Wilma Floods Florida |
| Description |
Dark pools of water covered sections of Florida the day after Hurricane Wilma cut diagonally across the state. The patterns of flooding shown in this image are more a reflection of land use than the intensity of the storm. Wilma moved from the Gulf of Mexico in the west, over the Everglades, and then pounded the populated eastern shore as it made its exit into the Atlantic. The Category 3 hurricane brought heavy rain, which caused the inland flooding seen here. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image on October 25, 2005. Shown in false color to increase the contrast between water and land, the image presents water in black and blue, vegetation in bright green, and clouds in pale blue and white. The lower image, taken on September 14, 2005, shows southern Florida under normal conditions. The most obvious flooding is in the Everglades, where the wetlands readily soaked up the downpour. Elevated roads form pale strips of green through the wetlands, which are dark with water in the wake of the storm. Between the Everglades and Lake Okeechobee is a lighter green arch of agricultural land. Dark squares hint at the possibility of flooded fields, but the presence of water in a few fields in the September image also suggests that some of the flooding may be intentional. Along the eastern shore of the peninsula, it is as if someone drew a line to mark out the edge of the wetlands from the pale green, grey, and tan grid of cities, including Miami and Fort Lauderdale. In fact, the line defines the boundary of Everglades National Park in the south. To the east of the park, the wetlands have been drained as cities sprung up. Here, no flooding is obvious, but the image shows signs of run-off. The Atlantic is bright blue with sediment. The sediment may have entered the water with flood water draining into the sea, it may be from storm-eroded beaches, or it may be sediment from the ocean floor brought to the surface with the churning of the sea under Wilma's winds. The bright ocean color in the Gulf of Mexico west of Florida is almost certainly caused by sediment from the ocean floor.
