After meandering off the coast of western Australia, Cyclone Fay finally
came ashore back on the 27th of March 2004 as a powerful Category 4 cyclone
with maximum sustained winds estimated at 115 knots (132 mph). The cyclone
quickly weakened over land. The Tropical Rainfall Measuring Mission (TRMM)
satellite captured several unique images of Fay along its path (please, see
the previous TRMM story on Cyclone Fay).
The TRMM-based, near-real time Multi-satellite Precipitation Analysis
(MPA) at the NASA Goddard Space Flight Center monitors rainfall over
the global tropics. MPA rainfall totals are shown for western Australia
and the eastern Indian Ocean in association with the passage of Fay for
the period 20 to 27 March 2004. The heaviest rainfall totals are by far
and away located over the eastern Indian Ocean. The darker red areas
show rainfall totals due to Fay on the order of 12 inches in this region.
The heaviest totals appear to the right of the storm track (shown by the
white storm symbols plotted every 06Z). These heavy amounts are the product
of an intense rain band located well to the north west of the center that
was observed by TRMM starting back on the 19th of March. The highest totals
over land appear right along the coast and are on the order of 3 to 5 inches
(green areas). A swath of 1 to 2 inch amounts (blue areas) extends inland
over Western Australia.
TRMM is a joint mission between NASA and the Japanese space agency JAXA.
