From page 97...
... The National Hurricane Center and the Joint Typhoon Warning Center include TMI in their storm discussions that outline how the data have affected their warning positions or provided insight on storm structure that directly influences storm intensity estimates and/or short-term intensity trends. This appendix provides examples of how TMI data are used for intensity estimates and fixing storm locations.

... Tropical Cyclone Size and Structure: Genevieve "The latest TRMM pass at 0055 UTC indicates Genevieve may not be vertically aligned with different center fixes from the 85 GHz and 37 GHz channels. Thus the initial intensity is held at 60 knots for this advisory." (From Tropical Storm Genevieve Discussion Number 9 at 8 pm August 27, 2002.)
