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 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.

| Description |
QuikSCAT Science Team [ http://winds.jpl.nasa.gov/ ], and the Jet Propulsion Laboratory., The 2007 Atlantic hurricane season had three named storms, but no hurricanes until the middle of August, when Tropical Storm Dean formed. By August 20, when the QuikSCAT satellite captured the data used to make this image, Dean was an extremely powerful Category 4 [ http://www.nhc.noaa.gov/aboutsshs.shtml ] hurricane. 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.

Hurricane Ivan |
| Description |
Hurricane Ivan continues to churn quickly across the Caribbean Sea, moving northwest at about 20 kilometers per hour (13 mph). In this image, captured by the Sea-viewing Wide Field of View Sensor (SeaWiFS [ http://seawifs.gsfc.nasa.gov/SEAWIFS.html ]) on September 10, 2004, the storm is approaching Jamaica and Cuba, seen obliquely on the left edge of the image. At the time this image was taken, Ivan?s winds had decreased to 220 kilometers per hour (140 mph), and the storm was producing 15 to 25 centimeters (6 to 10 inches) of rain. Ivan was expected to hit Jamaica late on September 10, and then move north over Cuba and into Florida. For information about Hurricane Ivan, please visit the National Hurricane Center [ http://www.nhc.noaa.gov/ ].

Hurricane Wilma
| Title |
Hurricane Wilma |
| Description |
On the morning of October 19, 2005, National Oceanographic and Atmospheric Administration (NOAA) aircraft measured a pressure of 882 millibars in the center of Hurricane Wilma—the lowest pressure ever measured in an Atlantic hurricane. This low pressure earned Wilma the status of the strongest hurricane ever recorded in the Atlantic. As of October 20, the storm was moving northward through the western Caribbean Sea and toward the Yucatan Channel, which separates Mexico from Cuba. Predictions at that time were that once Wilma moved into the Gulf of Mexico, westerly winds would begin steering the storm toward Florida. In this image, Wilma is sprawled across the entire western Caribbean Sea, with bands of clouds reaching from the Yucatan Peninsula and Honduras (left and lower left, respectively) all the way to Cuba and Jamaica (upper right and center right edge). The image is one frame of an animation that shows the development of the storm between 8:15 p.m. (Eastern Daylight Time) on October 18 and 4:45 p.m. on October 19 (00:15 to 20:45 UTC on October 19). At the beginning of the animation, the core of the storm is a smaller, bright disk of clouds off the coast of Honduras. Over the course of the animation, Wilma grows larger and spins and wobbles its way west-northwest. Thunderstorms embedded in the hurricane's spiraling cloud bands explode and then subside over the course of the animation. This image shows visible data collected by NOAA's Geostationary Operational Environmental Satellite (GOES), combined with land surface data collected by NASA's Moderate Resolution Imaging Spectroradiometer instrument. The animation uses GOES infrared data during the nighttime part of the animation (up until about 8:45 a.m on October 19) and visible data in the daytime portion.
