Pulse Thunderstorms, Overview and Warning Strategies
Warren Snyder (NWS ALY) and Michael Cammarata (NWS CAE)
1) Introduction
Objectives:
- Improve the lead time and probability of detection of severe pulse thunderstorms
- Review what pulse thunderstorms and ordinary cells are
- Identify when ordinary cells are likely to become severe
- How pulse thunderstorms effect GPRA goals
- How to warn for pulse thunderstorms using methodologies from Cerniglia and Snyder
- Best practices / operating strategies for pulse thunderstorm warning events from Columbia, SC.
2) Prerequisites
This is a basic course.
There are no prerequisites.
3) Teletraining Installation Instructions
4) Training Session Options:
A.) The interactive VISITview
training session. (To be used
with a VISIT instructor leading the session
). Click
here
to signup for teletraining. The session will last 75 minutes.
This teletraining session uses the VISITview software, where Windows PC with an Internet connection is needed.
B.) local Visitview session - This is the same version of the lesson
used in a "live" VISITview teletraining session, but no connection
is made to an external VISITview server. You may download the file
off this page and go through the lesson on your own in "local mode"
by starting the "visitlocal.bat" file. Talking points are not included
in this lesson version, but can be viewed in a separate Web browser (
or printed out beforehand).
