This case reviews the use of the enhanced-V signature in the GOES-IR data. Previous studies by McCann(1981) have indicated the value of real-time satellite data in detecting and monitoring severe thunderstorms.
The goal of this teletraining session is to review the correct identification and interpretation of the enhanced-V.

This training installment used the 29 March 1998 Minnesota tornado case to provide an analysis of the enhanced-V satellite signature using GOES data. This signature is an important indicator of severe weather which can be used during weather warning operations to augment radar information. Also shown are imagery from the Jarrell, Texas tornado outbreak. Of particular interest with this case, is the 1km IR AVHRR data which was available for an interesting comparison with GOES.
