A classical intense hurricane is shown in this view of Juliette,
captured by the Multi-angle Imaging SpectroRadiometer on
September 26, 2001.
On the left is a true-color image produced by MISR's
nadir (vertical-viewing) camera. Impressive spiral arms wrapped
around the eye are apparent. Several areas of convective cloud can
be discerned along the arms. The eye of the storm is centered at
18.8N latitude and 109.8W longitude (about 480 kilometers south of
Cabo San Lucas, Mexico). On the right is the cloud-top height field
derived using automated computer processing of the data from multiple
MISR cameras. Relative height variations are well represented, such
as the clearing within the storm's eye. The stereoscopic data
processing algorithm used to generate these results is still being
refined. Future versions of this product may show modest changes in
the height values compared to the preliminary values displayed here.
Areas where heights could not be retrieved are shown in black. The
observations cover a 380-kilometer swath width, and were acquired
during Terra orbit 9442.
On September 25, Air Force reconnaissance aircraft recorded minimum
sea level pressures of 923 millibars -- the lowest measurement for
an eastern North Pacific hurricane since 1973. According to the
National Hurricane Center, deep convection surrounding Juliette's eye
began to weaken on the morning of September 26. The strength of this
potentially dangerous hurricane continued to diminish over the next
few days as the storm approached cooler waters. It travelled in a
north-northwest direction over the Pacific Ocean until reaching
the tip of Baja Peninsula, where the heaviest rainfall and winds
were confined. Juliette was downgraded to a tropical storm on
September 29, and to a tropical depression on September 30. The National Hurricane Center predicted Juliette's cyclonic circulation to be mostly dissipated by October 4.
Eyes, look your last!
Arms, take your last embrace!
