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 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 |
| Description |
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 as Observed by NASA's Spaceborne Atmospheric Infrared Sounder (AIRS) |
| Original Caption Released with Image |
Hurricane Ivan is the most powerful hurricane to hit the Caribbean in 10 years. On September 7 and 8 it damaged 90 percent of the homes in Grenada and killed at least 16 people as it swept over Grenada, Barbados and the other islands in the area. By Thursday morning on September 9, Ivan's sustained winds reached 160 mph making it a rare category 5 hurricane on the Saffir-Simpson scale. By Monday September 13, Ivan is blamed for 67 deaths and skirts western Cuba with winds clocked at 156 mph. The National Hurricane Center predicted the eye of Ivan will make landfall across Mobile Bay in Alabama late Wednesday or early Thursday. These images of Hurricane Ivan were acquired by the AIRS infrared, microwave, and visible sensors on September 15 at 1:30 pm local time as the storm moves in to Alabama. Ivan at category 4 strength is about 150 miles south of Mobile, Alabama and is moving north at 14 mph. Maximum sustained winds are reported to be at 135 mph and extend 105 miles from the center, while tropical storm-force winds extend 290 miles from the center. Ivan pounded the Gulf coast all day Wednesday, and is expected to make landfall between midnight and 3am in Mobile Bay, Alabama. This image shows how the storm looks through an AIRS Infrared window channel, and reveals a very large eye - about 75 km (50 miles) across. Window channels measure the temperature of the cloud tops or the surface of the Earth in cloud-free regions. The lowest temperatures are associated with high, cold cloud tops that make up the top of the hurricane. The infrared signal does not penetrate through clouds, so the purple color indicates the cool cloud tops of the storm. In cloud-free areas, the infrared signal is retrieved at the Earth's surface, revealing warmer temperatures. Cooler areas are pushing to purple and warmer areas are pushing to red. The microwave image (figure 2) reveals where the heaviest precipitation in Ivan is taking place. The blue areas within the storm show the location of this heavy precipitation. Blue areas outside of the storm where there are moderate or no clouds are where the cold (in the microwave sense) sea surface shines through. The image shows that the largest area of intense convection/precipitation is in the NE quadrant, centered near New Orleans. There is a smaller but still quite intense area in the SE quadrant trailing the center of the storm that might impact the Alabama coast. Image Journal, September 13, Friday, 1:30 pm. - visible/near-infrared The Atmospheric Infrared Sounder Experiment, with its visible, infrared, and microwave detectors, provides a three-dimensional look at Earth's weather. Working in tandem, the three instruments can make simultaneous observations all the way down to the Earth's surface, even in the presence of heavy clouds. With more than 2,000 channels sensing different regions of the atmosphere, the system creates a global, 3-D map of atmospheric temperature and humidity and provides information on clouds, greenhouse gases, and many other atmospheric phenomena. The AIRS Infrared Sounder Experiment flies onboard NASA's Aqua spacecraft and is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., under contract to NASA.

The center of the storm is 170 miles (275 km) southeast of Barbados and moving west at 21 mph (33 km/hr). Maximum sustained winds near 105 mph which extend outward at this force for 70 miles (110 km).

September 8, Wednesday, 1:30 am. - microwave, 89GHz September 10, Friday, 1:30 pm. - infrared, 12micron Ivan closes in on Jamaica. With only 85 miles between the storm and the island, Ivan's winds at category 4 are sustained at 145 mph (230 km/hr). Hurricane-strength winds extend up to 60 miles from the center of Ivan, and tropical-storm force winds are up to 175 miles from the center. Ivan is now better organized and has a well-defined eye. After Ivan leaves Jamaica, it is expected to hit western Cuba, probably making landfall later Sunday as a CAT 4 hurricane.

Tropical-storm force winds are up to 205 miles from the center. The infrared image shows that the eye has grown quite large - perhaps 40 km (25 miles) across - which is sometimes an indication of weakening but may not be in this case. The surface pressure at the time of this image was estimated by the National Hurricane Center at 915 mb and falling - consistent with a very intense and strengthening hurricane. September 13, Friday, 1:30 pm. - microwave, 89GHz The microwave image shows that Ivan has again developed two distinct convective centers, separated by about 250 km. That pattern developed on September 5 and persisted for 4 days. It disappeared while the storm was passing over Jamaica, but it has now re-formed. |

Hurricane Ivan as Observed by NASA's Spaceborne Atmospheric Infrared Sounder (AIRS) |

Hurricane Ivan is the most powerful hurricane to hit the Caribbean in 10 years. On September 7 and 8 it damaged 90 percent of the homes in Grenada and killed at least 16 people as it swept over Grenada, Barbados and the other islands in the area. By Thursday morning on September 9, Ivan's sustained winds reached 160 mph making it a rare category 5 hurricane on the Saffir-Simpson scale. By Monday September 13, Ivan is blamed for 67 deaths and skirts western Cuba with winds clocked at 156 mph. The National Hurricane Center predicted the eye of Ivan will make landfall across Mobile Bay in Alabama late Wednesday or early Thursday. These images of Hurricane Ivan were acquired by the AIRS infrared, microwave, and visible sensors on September 15 at 1:30 pm local time as the storm moves in to Alabama. Ivan at category 4 strength is about 150 miles south of Mobile, Alabama and is moving north at 14 mph. Maximum sustained winds are reported to be at 135 mph and extend 105 miles from the center, while tropical storm-force winds extend 290 miles from the center. Ivan pounded the Gulf coast all day Wednesday, and is expected to make landfall between midnight and 3am in Mobile Bay, Alabama. This image shows how the storm looks through an AIRS Infrared window channel, and reveals a very large eye - about 75 km (50 miles) across.

Hurricane Ivan as Observed by NASA's Spaceborne Atmospheric Infrared Sounder (AIRS) |

Hurricane Ivan is the most powerful hurricane to hit the Caribbean in 10 years. On September 7 and 8 it damaged 90 percent of the homes in Grenada and killed at least 16 people as it swept over Grenada, Barbados and the other islands in the area. By Thursday morning on September 9, Ivan's sustained winds reached 160 mph making it a rare category 5 hurricane on the Saffir-Simpson scale. By Monday September 13, Ivan is blamed for 67 deaths and skirts western Cuba with winds clocked at 156 mph. The National Hurricane Center predicted the eye of Ivan will make landfall across Mobile Bay in Alabama late Wednesday or early Thursday. These images of Hurricane Ivan were acquired by the AIRS infrared, microwave, and visible sensors on September 15 at 1:30 pm local time as the storm moves in to Alabama. Ivan at category 4 strength is about 150 miles south of Mobile, Alabama and is moving north at 14 mph. Maximum sustained winds are reported to be at 135 mph and extend 105 miles from the center, while tropical storm-force winds extend 290 miles from the center. Ivan pounded the Gulf coast all day Wednesday, and is expected to make landfall between midnight and 3am in Mobile Bay, Alabama. This image shows how the storm looks through an AIRS Infrared window channel, and reveals a very large eye - about 75 km (50 miles) across. Window channels measure the temperature of the cloud tops or the surface of the Earth in cloud-free regions. The lowest temperatures are associated with high, cold cloud tops that make up the top of the hurricane. The infrared signal does not penetrate through clouds, so the purple color indicates the cool cloud tops of the storm. In cloud-free areas, the infrared signal is retrieved at the Earth's surface, revealing warmer temperatures. Cooler areas are pushing to purple and warmer areas are pushing to red. The microwave image (figure 2) reveals where the heaviest precipitation in Ivan is taking place. The blue areas within the storm show the location of this heavy precipitation. Blue areas outside of the storm where there are moderate or no clouds are where the cold (in the microwave sense) sea surface shines through. The image shows that the largest area of intense convection/precipitation is in the NE quadrant, centered near New Orleans. There is a smaller but still quite intense area in the SE quadrant trailing the center of the storm that might impact the Alabama coast.

Figure 1: AIRS infrared channel 2333 (2616 cm-1), Figure 2: Total Water Vapor retrieved from AIRS infrared and AMSU-A microwave data September 18, 2003 These two false-color images show Hurricane Isabel viewed by the AIRS and AMSU-A instruments at 1:30 EDT in the morning of Thursday September 18, 2003. Isabel will be ashore within 12 hours, bringing widespread flooding and destructive winds. In figure 1 on the left, data retrieved by the AIRS infrared sensor shows the hurricane's eye as the small ring of pale blue near the upper left corner of the image. The dark blue band around the eye shows the cold tops of hundreds of powerful thunderstorms. These storms are embedded in the 120 mile per hour winds swirling counterclockwise around Isabel's eye. Cape Hatteras is the finger of land north-northwest of the eye. Isabel's winds will soon push ashore a 4- to 8-foot high mound of 'storm surge' and accompanying high surf, leading to flooding of Cape Hatteras and other islands of North Carolina's Outer Banks. Also seen in the image are several organized bands of cold, (blue) thunderstorm tops being pulled into the storm center. Other thunderstorm are forming north of the islands of Jamaica, Cuba, Hispaniola and Puerto Rico near the bottom of the picture. Figure 2 shows the geographical distribution and total amount of atmospheric water vapor associated with Isabel as inferred by AIRS and AMSU-A. Very humid areas appear deep red and surround the storm's eye in the ring of thunderstorms, as seen above. The enhancement of atmospheric water vapor in the storm is maintained by evaporation from the wind-churned sea surface. In turn, the water vapor powers the thunderstorms by condensing as rain and releasing the ocean's warmth into the atmosphere to drive strong convection. This makes Isabel and other hurricanes 'heat engines,' converting ocean water's warmth into atmospheric gales. Isabel is weakening as it move ashore and loses its supply of energy from warm water, but not before raining an expected 6-12 inch thick layer of its water over an area extending from South Carolina and New England to the midwest and southern Canada. Paler blue areas in the water vapor image show less humid heights of the atmosphere, which are associated with the colder thunderstorm tops seen in the infrared image.
