NASA During this year's Atlantic hurricane season, NASA is redoubling its efforts to probe the inner workings of hurricanes and tropical storms with two unmanned Global Hawk aircraft flying over storms and two new space-based missions. NASA's airborne Hurricane and Severe Storm Sentinel, or HS3 mission, will revisit the Atlantic Ocean for the fourth year in a row. HS3 is a collaborative effort that brings together several NASA centers with federal and university partners to investigate...

HS3 Mission Identifies Area of Strong Winds And Heavy Rain In Hurricane Ingrid
2013-09-27 11:09:19

NASA One of the instruments that flew aboard one of two unmanned Global Hawk aircraft during NASA's HS3 mission was the Hurricane Imaging Radiometer known as HIRAD. HIRAD identified an area of heavy rains and and likely strong winds in Hurricane Ingrid by measuring surface wind speeds and rain rates using its rectangular antenna to track activity on the ocean’s surface. NASA's Global Hawk 871 is the over-storm Global Hawk that carried HIRAD on a flight over Hurricane Ingrid on Sept....

Gabrielle's Remnants And New Tropical Storm Humberto Investigated By NASA
2013-09-09 12:53:05

NASA Tropical Depression Nine formed yesterday, Sept. 8 in the far eastern Atlantic, and NASA's Aqua satellite saw it strengthen into Tropical Storm Humberto today, Sept. 9 at 5 a.m. EDT. As that storm strengthened, the remnants of the once-tropical-storm Gabrielle continued to struggle near the Bahamas as NASA's HS3 mission investigated. Tropical Storm Humberto is affecting the Cape Verde Islands, so there's a tropical storm warning in up for the southern islands of Maio, Santiago,...

Global Hawk Aircraft Takes A Look At Saharan Air Layer And Tropical Storm Erin Remnants
2013-08-24 04:20:17

redOrbit Staff & Wire Reports - Your Universe Online One of NASA’s two Global Hawk unmanned aircraft recently investigated the Saharan Air Layer (SAL) in the Eastern Atlantic Ocean as part of the ongoing Hurricane and Severe Storm Sentinel (H3) mission, officials from the US space agency revealed on Friday. In addition to studying this intensely dry, warm and sometimes dust-laden layer of the atmosphere which often overlies the cooler, more-humid surface air of the Atlantic Ocean,...

New Doppler Radar Will Measure Rain And Wind On This Summer's HS3 Mission
2013-08-01 09:29:29

NASA Most aircraft carrying Doppler radar look like they've grown a tail, developed a dorsal fin, or sprouted a giant pancake on their backs. But when the unmanned Global Hawk carries a radar system this summer, its cargo will be hard to see. The autonomous and compact High-altitude Imaging Wind and Rain Profiler, or HIWRAP, a dual-frequency conical-scanning Doppler radar, will hang under the aircraft's belly as it flies above hurricanes to measure wind and rain and to test a new method...

Long-Lived Hurricane Nadine Thoroughly Investigated By NASA's HS3 Mission
2012-10-05 15:19:29

NASA's Hurricane and Severe Storm Sentinel or HS3 scientists had a fascinating tropical cyclone to study in long-lived Hurricane Nadine. NASA's Global Hawk aircraft has investigated Nadine five times during the storm's lifetime. NASA's Global Hawk also circled around the eastern side of Hurricane Leslie when it initially flew from NASA's Dryden Research Flight Center, Edwards Air Force Base, Calif. to the HS3 base at NASA's Wallops Flight Facility, Wallops Island, Va. on Sept. 6-7, 2012....

NASA's Hurricane Mission A Reality Due To Cutting-Edge Technology
2012-09-26 08:00:00

Cutting-edge NASA technology has made this year's NASA Hurricane mission a reality. NASA and other scientists are currently flying a suite of state-of-the-art, autonomously operated instruments that are gathering difficult-to-obtain measurements of wind speeds, precipitation, and cloud structures in and around tropical storms. "Making these measurements possible is the platform on which the instruments are flying," said Paul Newman, the deputy principal investigator of NASA's Hurricane and...

Tropical Storm Nadine's 'Birth' Attended By NASA Global Hawk And Satellites
2012-09-13 07:55:22

Tropical Depression 14 strengthened into Tropical Storm Nadine while NASA's Hurricane Severe Storm Sentinel Mission, or HS3 mission, was in full-swing and NASA's Global Hawk aircraft captured the event. While the Global Hawk was gathering data over the storm, NASA satellites were also analyzing Nadine from space. NASA's Global Hawk landed back at Wallops Flight Facility, Wallops Island, Va., after spending a full day gathering data from the 14th Atlantic Tropical Depression that...

Unmanned Aircraft To Study Hurricanes
2012-06-04 04:43:33

Beginning this summer and over the next several years, NASA will be sending unmanned aircraft dubbed "severe storm sentinels" above stormy skies to help researchers and forecasters uncover information about hurricane formation and intensity changes. Several NASA centers are joining federal and university partners in the Hurricane and Severe Storm Sentinel (HS3) airborne mission targeted to investigate the processes that underlie hurricane formation and intensity change in the Atlantic...
