| Description |
This pair of images of the Long Island, New York region is a comparison of an optical photograph (top) and a radar image (bottom), both taken in darkness in April 1994. The photograph at the top was taken by the Endeavour astronauts at about 3 a.m. Eastern time on April 20, 1994. The image at the bottom was acquired at about the same time four days earlier on April 16, 1994 by the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) system aboard the space shuttle Endeavour. Both images show an area approximately 100 kilometers by 40 kilometers (62 miles by 25 miles) that is centered at 40.7 degrees North latitude and 73.5 degrees West longitude. North is toward the upper right. The optical image is dominated by city lights, which are particularly bright in the densely developed urban areas of New York City located on the left half of the photo. The brightest white zones appear on the island of Manhattan in the left center, and Central Park can be seen as a darker area in the middle of Manhattan. To the northeast (right) of the city, suburban Long Island appears as a less densely illuminated area, with the brightest zones occurring along major transportation and development corridors. Since radar is an active sensing system that provides its own illumination, the radar image shows a great amount of surface detail, despite the night-time acquisition. The colors in the radar image were obtained using the following radar channels: red represents the L-band (horizontally transmitted and received), green represents the L-band (horizontally transmitted and vertically received), blue represents the C- band (horizontally transmitted and vertically received). In this image, the water surface - the Atlantic Ocean along the bottom edge and Long Island Sound shown at the top edge - appears red because small waves at the surface strongly reflect the horizontally transmitted and received L-band radar signal. Networks of highways and railroad lines are clearly visible in the radar image, many of them can also be seen as bright lines in the optical image. The runways of John F. Kennedy International Airport appear as a dark rectangle in Jamaica Bay on the left side of the image. Developed areas appear generally as bright green and orange, while agricultural, protected and undeveloped areas appear darker blue or purple. This contrast can be seen on the barrier islands along the south coast of Long Island, which are heavily developed in the Rockaway and Long Beach areas south and east of Jamaica Bay, but further to the east, the islands are protected and undeveloped. |

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. |

Hurricane Charley
| Title |
Hurricane Charley |
| Description |
The state of Florida has suffered its second direct hit by a tropical cyclone in as many days. On Thursday August 12, 2004, Bonnie came ashore in the Florida panhandle near Apalachicola as a tropical storm. Charley, however, became far a more dangerous Category 4 storm before it slammed into the southwest coast of Florida. Just as it did with Bonnie, the Tropical Rainfall Measuring Mission (TRMM) satellite followed Charley's progress across the Caribbean and Cuba, which suffered a direct hit. The images and data collected by TRMM can provide valuable estimates of storm location and storm intensity to the NOAA Tropical Prediction Center (also known as the National Hurricane Center). Similar to Bonnie, Charley began as a tropical depression near the Windward Islands. Tropical depression number three (TD #3) formed on August 9th, 2004 just to the southeast of Grenada. TD #3 then moved west-northwest into the lower eastern Caribbean and strengthened into a tropical storm on the morning (local time) of the 10th. The image shown above was taken at 05:43 UTC (1:43 am EDT) on 10 August 2004. The image displays the horizontal distribution of rain intensity obtained from the TRMM satellite. Rain rates in the center part of the swath are from the TRMM Precipitation Radar (PR), the first and only precipitation radar in space. The PR can provide fine resolution rainfall data and details on the vertical structure. 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 shows Charley just before it became a named tropical storm. The storm appears rather small with no apparent banding in the rain field. But, most of the rain (green moderate and blue light) is concentrated near the center and IR data (white background) indicates that there is good outflow with the storm. Charley continued moving west-northwest into the central Caribbean and slowly strengthened into a minimal Category 1 hurricane on the afternoon (local time) of the 11th with maximum sustained winds reported at 65 knots (75 mph) based on measurements by an Air Force Reserve Hurricane Hunter Aircraft. At this point, Charley was just south of Jamaica. The storm now began to curve towards the right taking a more northwestward track as it passed around the western side of a subtropical ridge to its north. Charley continued to slowly intensify. Early on the afternoon of the 12th (local time), Charley became a Category 2 hurricane with sustained winds of 85 knots (98 mph). Charley then turned even more to the north ahead of an upper-level trough and headed straight for western Cuba. On the evening of the 12th of August, Charley passed just to the east of the Isle of Youth and slammed into western Cuba where it crossed the island just west of Havana before emerging into the southeastern Gulf of Mexico. The image taken at 04:32 UTC (12:32 am EDT) on Friday August 13 shows Charley, directly over Cuba. The PR missed the center of the storm but a perfectly symmetrical ring of moderate rain (green circle) marks the center of Charley by the TMI. The rain field appears tightly concentrated near the center which is surrounded by an area devoid of rain known as a dry slot showing where drier air has been entrained into the storm's circulation. At the time of this image, Charley's sustained winds were 90 knots (104 mph). After coming off of Cuba, Charley intensified into a powerful Category 4 storm, with sustained winds measured at 145 mph, before slamming into the southwest coast of Florida near Captiva Island.

Hurricane Dean
| Title |
Hurricane Dean |
| Description |
The 2007 Atlantic hurricane season had been running for several months before it saw its first hurricane, Dean. Dean began as a wave-like disturbance in the cloud bands off South America, which gathered together to form a storm system on August 13. By August 18, Dean had grown in power to become a Category 4 hurricane, [ http://www.nhc.noaa.gov/aboutsshs.shtml ] swirling in the Caribbean Sea. The storm caused great damage to Jamaica and Grand Cayman Island, among other Caribbean islands, and as of August 19, it was forecast to come ashore on the Mexican Yucatan Peninsula not far from the border with Belize. Forecasters at the National Hurricane Center [ http://www.nhc.noaa.gov/index.shtml? ] were also expecting the storm to continue to gather power to Category 5 strength. While weather and Earth science satellites are known for getting a perspective on storms as they orbit the Earth, they were not the only sensors viewing Hurricane Dean from high above. Astronauts aboard the International Space Station and the crew of the Space Shuttle "Endeavour" passed over the storm on August 18. These two photographs were taken by astronauts on "Endeavour" moments from each other. The first is a close-up of the eye of the storm, the second is a wider-angle view, both taken by a handheld camera around noon local time. Hurricane Dean showed a deep and well-defined eye at the center of the storm, with powerful thunderstorms around the eyewall sending up tall towers of clouds. In the close-up view, these towering clouds appear to be casting shadows on the cloud deck below them. The deep eye of the storm has a clear three-dimensional shape in these oblique angle photographs, but the camera angle does not allow us to see down the bottom of the storm. At the time of these photographs, Hurricane Dean was passing just south of Jamaica as a Category 4 storm with sustained winds as high as 240 kilometers per hour (150 miles per hour).

Hurricane Dean |
| Description |
Hurricane Dean was the first hurricane of the 2007 Atlantic Hurricane Season. The storm system formed off the coast of South America on August 13. It traveled west, building strength from the warm waters as it headed towards the South American coast and the southern arc of the Caribbean Islands. By August 17, it had grown in power to become a Category 3 hurricane, [ http://www.nhc.noaa.gov/aboutsshs.shtml ] and forecasters were calling for it to potentially gain yet more strength as it passed over the warm waters of the Caribbean Sea. Dean was projected to cause major damage. Mexican authorities, according to news sources, were warning residents in the Yucatan Peninsula of the danger of the coming storm, which was projected to strike the peninsula. The storm might also brush against the islands of Hispaniola, Jamaica, and Cuba among others. Some forecasters were concerned about the possibility of Dean developing into super storm in the Gulf of Mexico, where storm surge and waves as well as winds might pose significant dangers to the oil and gas platforms. This data visualization of the hurricane shows observations from the QuikSCAT satellite on August 16, 2007, at 6:55 p.m. local time (21:55 UTC). At this time, Dean was poised to cross the Windward Islands of the Caribbean, while grazing the coast of Venezuela on the South American mainland. Peak winds were around 160 kilometers per hour (100 miles per hour, 85 knots) at this time, according to Unisys Weather's Hurricane information page, [ http://weather.unisys.com/hurricane/ ] making Dean a Category 2 hurricane. The image depicts wind speed in color and wind direction with small barbs. White barbs point to areas of heavy rain. QuikSCAT measurements of the wind strength of Hurricane Dean and other tropical cyclones can be slower than actual wind speeds. QuikSCAT's scatterometer sends pulses of microwave energy through the atmosphere to the ocean surface and measures the energy that bounces back from the wind-roughened surface. The energy of the microwave pulses changes depending on wind speed and direction. To relate the radar signal to actual wind speed, scientists compare measurements taken from buoys and other ground stations to data the satellite acquired at the same time and place. Because the high wind speeds generated by cyclones are rare, scientists do not have corresponding ground information to know how to translate data from the satellite for wind speeds above 50 knots (about 93 km/hr or 58 mph). Also, the unusually heavy rain found in a cyclone distorts the microwave pulses in a number of ways, making a conversion to exact wind speed difficult. Instead, the scatterometer provides a nice picture of the relative wind speeds within the storm and shows wind direction.

Hurricane Dean |
| Description |
Dean may have been the first Atlantic hurricane of the 2007 season, but days after first forming, it was also classified among the strongest hurricanes recorded. Dean became a Category 5 hurricane [ http://www.nhc.noaa.gov/aboutsshs.shtml ] before coming ashore on Mexico's Yucatan Peninsula on August 21. Dean began as a wave-like disturbance in the cloud bands off South America, which gathered together to form a storm system on August 13. Fueled by the deep warm waters of the Caribbean, Dean quickly grew into a major hurricane, reaching its peak just before coming ashore. As it traveled across the Caribbean, the storm also caused great damage to Jamaica, Grand Cayman Island, and other Caribbean islands. This data visualization of the hurricane shows observations from the QuikSCAT satellite on August 20, 2007, at 5:31 p.m. local time (23:31 UTC). At this time, Dean was in the Gulf of Mexico between Cuba, Jamaica, and the Central American peninsula heading towards the Yucatan Peninsula. Peak winds were around 250 kilometers per hour (155 miles per hour, 135 knots) at this time, according to Unisys Weather's Hurricane information page. [ http://weather.unisys.com/hurricane/ ] With these wind speeds, Dean just reached Category 5 status. The image depicts wind speed in color and wind direction with small barbs. The highest wind speeds, shown in purple, surround the center of the storm. The strongest winds on the north side of the eyewall are depicted in pink. Areas of heavy rain, shown with white barbs, correspond with stronger winds. QuikSCAT measurements of the wind strength of Dean and other tropical cyclones can be slower than actual wind speeds. QuikSCAT's scatterometer sends pulses of microwave energy through the atmosphere to the ocean surface and measures the energy that bounces back from the wind-roughened surface. The energy of the microwave pulses changes depending on wind speed and direction. To relate the radar signal to actual wind speed, scientists compare measurements taken from buoys and other ground stations to data the satellite acquired at the same time and place.

The image depicts wind speed in color and wind direction with small barbs. White barbs point to areas of heavy rain. The center of the storm is dominated by purple, indicating high wind speeds. Pale pink circles the eye where winds were off the scale. Dark red and orange areas spread some distance from the eye: Dean was a large and powerful storm. Dean began as a wave-like disturbance in the cloud bands off South America, which gathered together to form a storm system on August 13. By August 18, Dean had grown in power to become a Category 4 hurricane, [ http://www.nhc.noaa.gov/aboutsshs.shtml ] swirling in the Caribbean Sea. The storm caused great damage to Jamaica and Grand Cayman Island, among other Caribbean islands, and as of August 19, it was forecast to come ashore on the Mexican Yucatan Peninsula not far from the border with Belize. Forecasters at the National Hurricane Center [ http://www.nhc.noaa.gov/index.shtml? ] were also expecting the storm to continue to gather power to Category Five strength. When QuikSCAT measured the storm on August 20, 2007, at 8:04 a.m. local time (14:04 UTC), Dean was in the Gulf of Mexico between Cuba, Jamaica, and the Central American peninsula heading towards the Yucatan Peninsula. Peak winds were around 240 kilometers per hour (150 miles per hour, 130 knots) at this time, according to Unisys Weather's Hurricane information, [ http://weather.unisys.com/hurricane/ ] making Dean a powerful Category Four hurricane. QuikSCAT measurements of the wind strength of Dean and other tropical cyclones can be slower than actual wind speeds. QuikSCAT's scatterometer sends pulses of microwave energy through the atmosphere to the ocean surface and measures the energy that bounces back from the wind-roughened surface. The energy of the microwave pulses changes depending on wind speed and direction. To relate the radar signal to actual wind speed, scientists compare measurements taken from buoys and other ground stations to data the satellite acquired at the same time and place. Because the high wind speeds generated by cyclones are rare, scientists do not have corresponding ground information to know how to translate data from the satellite for wind speeds above 50 knots (about 93 km/hr or 58 mph). Also, the unusually heavy rain found in a cyclone distorts the microwave pulses in a number of ways, making a conversion to exact wind speed difficult. Instead, the scatterometer provides a nice picture of the relative wind speeds within the storm and shows wind direction. NASA image courtesy of David Long, Brigham Young University, on the |

Hurricane Dennis
| Title |
Hurricane Dennis |
| Description |
The swirling clouds of Tropical Storm Dennis span from the northern tip of Venezuela to the southern half of the island of Hispaniola in this Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) image. NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image on July 6, 2005, at 10:05 a.m. local time (15:05 UTC) when Dennis was building to winds of 110 kilometers per hour (70 mph). The storm was moving northwest across the Caribbean and should pass between the eastern arm of Haiti and Jamaica, hammering both with four to eight inches of rain. The National Hurricane Center [ http://www.nhc.noaa.gov/ ] predicts that Dennis may become a major hurricane—Category 3 or higher—by July 8. This image is available in additional resolutions from the MODIS Rapid Response System.

Hurricane Dennis
| Title |
Hurricane Dennis |
| Description |
Hurricane Dennis threaded its way between Jamaica and Haiti on a direct course for Cuba on July 7, 2005. The storm now has the distinctive hurricane form, with a well-defined eye surrounded by bands of swirling clouds. At 10:50 a.m. local time (15:50 UTC), when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA?s Terra [ http://terra.nasa.gov/ ] satellite took this image, Dennis was just below a Category 3 hurricane, with winds of 175 kilometers per hour (110 miles per hour) and stronger gusts. Less than an hour before this image was taken, the storm?s small dark eye was about 105 kilometers (65 miles) northeast of Kingston, Jamaica, and 170 kilometers (105 miles) south-southeast of Guantanamo, Cuba. The National Hurricane Center reports that Dennis is traveling northwest at about 24 kilometers per hour (15 mph). A storm of this size is a threat not just because of its powerful winds: Dennis is expected to produce heavy rain and coastal and inland flooding. Five to ten inches of rain may fall over Haiti, the Dominican Republic, Jamaica, Cuba, and the Cayman Islands, with as much as 15 inches falling in parts of Jamaica. Heavy rainfall can trigger flash floods and mudslides in mountainous regions. The storm will probably also raise tide levels by five to seven feet and generate large and dangerous waves. Dennis is expected to strengthen as it moves north towards the Gulf Coast of the United States. For official storm warnings and additional information, please visit the National Hurricane Center [ http://www.nhc.noaa.gov/ ].

Hurricane Emily
| Title |
Hurricane Emily |
| Description |
Hurricane Emily is shown here in the Carribbean north of Venezuela on July 14, 2005. The image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite at 17:20 UTC (13:20 Eastern Daylight Time). At this time, it was a well developed and powerful hurricane with winds over 150 kilometers an hour (85 knots). It passed through the chain of islands known as the Windward Islands, causing one death in the city of St. George?s on Grenada. It is building up towards a Category 4 hurricane, the second strongest storm on the Saffir-Simpson intensity scale. Projections take it glancing off Jamaica, striking the Yucatan Peninsula in Mexico, and continuing across into the Gulf of Mexico to make landfall again somewhere near Brownsville, Texas on the border with Mexico and the United States. Predicting hurricane strength and intensity is challenging, and Emily might be either stronger or weaker than expected, and it may not stay on its predicted course. The hurricane has already become somewhat stronger than first anticipated. NASA image created by Jesse Allen, Earth Observatory, using data obtained from the MODIS Rapid Response team. |

Hurricane Emily |
| Description |
Hurricane Emily had come ashore in Mexico on July 20, 2005, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA?s Aqua [ http://aqua.nasa.gov/ ] satellite captured this image. The image shows the storm at 3:05 p.m. local time, roughly one day after Emily made landfall. The storm is bringing much needed rain into the parched Rio Grande drainage basin, though the arrival of this water as a deluge poses dangers and challenges even as it refills low water reservoirs slightly. Emily is a record-setting storm for many reasons. When it formed on July 11, Emily became the earliest fifth named storm on record. As it moved through the Caribbean, Emily intensified into a powerful Category 4 storm with winds over 250 km/hr (150 mph) and gusts as high as 300 km/hr (184 mph), making it the most powerful storm to form before August. The previous record was set by Hurricane Dennis, which ripped through the Caribbean during the first week of July 2005. Emily?s Category 4 status also made 2005 the only year to produce two Category 4 storms before the end of July. Emily is responsible for five deaths through the Caribbean, as well as considerable damage in places as far apart as the Lesser Antilles Islands and Jamaica to Mexico?s Yucatan Peninsula. Tornadoes spawned by Emily have also caused some damage in southern Texas. The MODIS Rapid Response Team provides this image in multiple resolutions.

Hurricane Emily was spinning through the Caribbean south of Jamacia on July 16, 2005, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite captured this image at 15:45 UTC (11:45 a.m. Eastern Daylight Time). At this time, Emily was a well-developed hurricane with winds over 230 kilometers an hour (125 knots) and gusts as high as 285 km/hr (155 knots). As shown in this satellite image, the storm is passing roughly east to west well south of Jamaica (around 160 kilometers, or 100 miles), but the heavy rains in the storm?s outer bands fell on an already sodden island still recovering from Hurricane Dennis, which similarly glanced the island on July 7. Emily?s rains caused flooding, which has resulted in four deaths on the island. Tourists in the Yucatan Peninsula are being evacuated from resort areas and beaches as the hurricane continues on track to make landfall there during the morning of July 18, 2005.

Hurricane Ivan
| Title |
Hurricane Ivan |
| Description |
With wind speeds topping 260 kilometers per hour (160 mph), Hurricane Ivan is roaring through the Caribbean as a deadly Category 5 storm. Early on September 9, 2004, the SeaWinds scatterometer aboard NASA's QuikSCAT satellite saw through Ivan's swirling clouds to measure wind speed 10 meters above the ocean surface. The result was this multi-colored image of the storm. Purple in the center of the storm shows the highest wind speeds, and green fringes around the outside of the storm show the lowest wind speeds. The black barbs indicate wind speed and direction at QuikSCAT's nominal 25 km resolution, white barbs indicate areas of heavy rain. Ivan strengthened after plowing over Grenada on Tuesday, September 7. The storm is forecast to move northwest over Jamaica and Cuba, then on to Florida. For more information, please visit the National Hurricane Center [ http://www.nhc.noaa.gov/ ]. NASA's Quick Scatterometer (QuikSCAT [ http://winds.jpl.nasa.gov ]) spacecraft was launched from Vandenberg Air Force Base, California on June 19, 1999. QuikScat carries the SeaWinds scatterometer, a specialized microwave radar that measures near-surface wind speed and direction under all weather and cloud conditions over the Earth's oceans. In recent years, the ability to detect and track severe storms has been dramatically enhanced by the advent of weather satellites. Data from the SeaWinds scatterometer is augmenting traditional satellite images of clouds by providing direct measurements of surface winds to compare with the observed cloud patterns in an effort to better determine a hurricane's location, direction, structure, and strength. Specifically, these wind data are helping meteorologists to more accurately identify the extent of gale-force winds associated with a storm, while supplying inputs to numerical models that provide advanced warning of high waves and flooding.

Hurricane Ivan |
| Description |
The Tropical Rainfall Measuring Mission [ http://trmm.gsfc.nasa.gov/ ] (TRMM) satellite flew over Hurricane Ivan as the storm struck several islands in the Caribbean between September 8 and September 13, 2004. Three times during its voyage through the Caribbean, Ivan reached Category 5 on the Saffir/Simpson scale, the strongest possible category. Ivan is the first Category 5 hurricane in the Caribbean since Mitch in the 1998. In the above image, the shades of gray show the cloud height with white indicating the highest clouds. Colors contours indicate the surface rainfall rate. A sequence of TRMM overflights shows the persistence of Hurricane Ivan?s strong eyewall. The eyewall survived the encounter with Jamaica on September 11, and developed into a double eyewall as Ivan struck Grand Cayman Island on the following day. The eyewall remained strong as the northern rainband struck Cuba?s Isle of Youth on September 13. A well organized eyewall is frequently a sign of an intense hurricane. TRMM [ http://trmm.gsfc.nasa.gov ] is a joint mission between NASA and the Japanese Aerospace Exploration Agency (JAXA).

This photo of Hurricane Ivan was snapped as the International Space Station passed over the eye of the storm on Saturday, September 11, 2004, about 15 minutes after 23:00 GMT (7 p.m. EDT). At the time, Ivan was wobbling west off its predicted course, its eye just missing Jamaica. The storm was a powerful and dangerous Category 5 storm with sustained winds reaching to 270 kilometers per hour (165 mph) and higher gusts. With tropical storm-force winds extending 280 kilometers from the eye, Ivan covers nearly the entire visible portion of the Earth in the above photo (22160). Portions of the ISS hardware (solar arrays) appear in the upper right corner.
