Detecting Low-level Thunderstorm Outflow Boundaries At Night Using GOES

Contributors*:

* Based on "Nighttime Detection of Low-level Thunderstorm Outflow Using a GOES Multispectral Image Product" by J. Dostalek et al



1) Introduction

    This case reviews the use of the GOES imager channels to detect and monitor the evolution of LTO boundaries at night. LTO boundaries have been monitored for years using the high resolution visible channel during the day. With the advent of the 3.9 micron channel on the GOES-8, -9 and –10 imager instrument, it is now possible to use the fog/stratus product to monitor the LTO boundaries during the night.

    The goal of this teletraining session is to review the use of the various GOES IR channels and products in monitoring LTO boundaries at night.

2) Prerequisites

    Prior to attending this session on low-level thunderstorm outflow (LTO) boundaries for 31 May 1996, you should review the following materials:

    • CIRA 3.9 micrometer tutorial section on fog/stratus
    • COMET SatMet1 CD-ROM module – Chapter 6 – Section 4 on the GOES 3.9 micrometer channel.
    • Markowski, Paul M., Erik N. Rasmussen, Jerry M. Straka, 1998: The Occurrence of Tornadoes in Supercells Interacting with Boundaries during VORTEX-95. Weather and Forecasting: Vol. 13, No. 3, pp. 852-859.

4) Training Session Options:

    A.) The interactive VISITview training session. (To be used with a VISIT instructor leading the session ). This session is no longer given on a regular basis, however if you want this teletraining you may send an email to visit@comet.ucar.edu to request this session. The session will last 60 minutes.

    B.) Web-based training session - a "stand alone" version viewed via a Web browser, with embedded talking points included. This lesson version may be viewed at any time. These slides are ideal for printing from the web-browser, just print preview first to choose portrait or landscape mode.

    C.) Web-based Visitview session - This version uses the VISITview software within a Web browser, may be viewed at any time. It retains all the functionality of the VISITview software which you see in a "live" teletraining session. The talking points are not included in this lesson version, but can be viewed in a separate Web browser (or printed out beforehand).

    D.) 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).
