Tropical Storm IDA
InfraRed Loop Water Vapor Loop
Note: The -24 degree C line (blue) of the GOES-12 water vapor channel (Ch3)
is discussed in the Ph.D. Dissertation by Melvin F. Martin, Jr.
available from the LSU Library.
Ongoing research performed by LSU Professor S.A. Hsu has further
substantiated that this line also follows closely the K-index number
of 28, indicating that thunderstorms are not likely within the
drier (shaded) areas.
