The dimensions of the Global Hawk were exaggerated by a factor of 10 so the viewer could see the UAV. The Global Hawk actual dimensions are 44.4 ft (13.5 m) length by 116.2 ft. (35.4 m) wingspan by 15.2 ft (4.6 m) height. The movie starts as the Global Hawk flies over Hurricane Karl to reveal a hot tower. Hot towers are important to understanding hurricane intensification because they can carry hot moist air through the high layer of cirrus clouds above a hurricane. Hot towers are hard to study because they go so high and they do not last very long. The structure of this storm is seen through reflectivity data where dbz is between 25 and 40. The HIWRAP data is colored based on the height from the surface. Red shows 12 km above sea level, orange is 10 km, yellow is 7.5 km, green is 6 km, and blue is under 6 km.

"description": "NASA scientists are investigating key questions about hurricanes in a new mission from the skies. This August, the East Pacific Origins and Characteristics of Hurricanes, or EPOCH, mission will fly over East Pacific storms to better understand how they form and intensify. EPOCH will conduct up to six 24-hour science flights using the Global Hawk unmanned aircraft. Three of the flights are being supported through a partnership with the NOAA UAS Program. Data will be collected using three instruments (EXRAD, HAMSR, and AVAPS) aboard the aircraft that will map out the 3-D patterns of temperature, pressure, humidity, precipitation, and wind speed - key factors that influence hurricane behavior. NASA scientists use a combination of ground, modeled, and satellite data to re-create multi-dimensional pictures of hurricanes and other major storms in order to study complex atmospheric interactions. || ",
