At approximately 0553 UTC (1:53 am EDT), on 2 Aug 2006, CloudSat flew over
the eye of Typhoon Prapiroon as it approached southern China.
The upper image is from the MODIS instrument on the NASA Aqua satellite,
to give an idea of how the storm looked from the top. The bottom image is
from NASA's new CloudSat satellite. The CloudSat radar flies in an
on-orbit formation with the Aqua satellite, approximately one minute
behind, as part of the A-Train constellation of satellites.
The red and purple areas indicate large amounts of cloud water. The blue
areas along the top of the clouds indicates cloud ice, while the wavy blue
lines on the bottom of the image indicate intense rainfall. Notice that
the solid line along the bottom of the panel, which is the ground or ocean
surface, disappears in many of these areas of intense precipitation. It is
likely that in these areas the precipitation rate exceeds 30mm/hr (1.18
inches/hour) based on previous studies.
The CloudSat radar data will be processed to estimate the total amount of
water and ice contained in this typhoon.
