Other contributors: Scott Bachmeier, Scott Lindstrom


The primary objective of this session is to maximize the information available from the GOES water vapor imagery during severe weather episodes, and how to effectively utilize this information with other available datasets.

Learning objectives:

  • 6.5 / 6.7 µm water vapor imagery
    • Identification of shortwaves / jet streaks
    • Cloud cover / clearing for destabilization
    • Identification of gravity waves
    • Storm induced dark zones
  • 7.4 µm water vapor imagery
    • Mid-level jet streaks
    • Relationship to elevated mixed layer

There is a post-training WES simulation jobsheet associated with this training.
