Hurricane Jeanne Cloud Height and Motion
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
After causing widespread destruction on Puerto Rico, Haiti, and the
Dominican Republic, Hurricane Jeanne was weakened to Tropical Storm
status for several days before it regained strength over the Bahamas as
a Category 2 hurricane. When Jeanne made landfall in U.S. territory on
September 26, it was the fourth major hurricane of the 2004 Atlantic
hurricane season to strike Florida. These visualizations of Hurricane
Jeanne on September 24 were captured by NASA’s Multi-angle Imaging
SpectroRadiometer (MISR). The still panels include a natural-color view
from MISR’s 26° forward-viewing camera (left) and a
two-dimensional map of cloud-top heights (right). In addition, a
#8220;multi-angle fly-over” is provided as an animation using
views from all nine MISR cameras.
The nine camera views which make up the animation were acquired over an
interval of about 7 minutes, and have been processed to give an
approximate perspective view. The cloud height map was produced by
automated computer recognition of the distinctive spatial features among
images acquired at different view angles. Two-dimensional maps of cloud
height such as these offer an opportunity to compare simulated cloud
fields against actual hurricane observations. Results indicate that
clouds within Jeanne had attained altitudes of more than 16 kilometers
above sea level. The height field pictured here is uncorrected for the
effects of cloud motion. Wind-corrected heights have higher accuracy but
sparser spatial coverage.
The Multi-angle Imaging SpectroRadiometer observes the daylit Earth
continuously and every 9 days views the entire globe between 82 degrees
north and 82degrees south latitude. The MISR Browse Image Viewer provides access to
low-resolution true-color versions of these images. These data products were generated
from a portion of the imagery acquired during Terra orbit 25372. The
still image panels cover an area of about 400 kilometers by 884
kilometers, and utilize data from within blocks 68 to 71 and within
World Reference System-2 path 10.
