RAMMB: VISIT Training Sessions - Mesoscale Convective Vortices

Mesoscale Convective Vortices

Objectives:

Remind you of the satellite presentation of Mesoscale Convective Vortices (MCVs)
Give hints on how to anticipate MCV genesis/decay
Discuss model performance of MCVs

Outline:

This is a basic course. There are no prerequisites.

LMS students - to begin the training, use the web-based video or audio playback options below (if present for this session).

Web-based video that can be taken at anytime (streamed, not recommended for low-bandwidth users). Be sure to have your speakers on and the volume loud enough to hear the presentation. For students who initiated this course in the NWS Learning Center (LMS), certificates of completion can be obtained from the learning center's "My Transcript" page upon completion of the associated quiz.
Audio playback (recommended for low-bandwidth users) - This is an audio playback version in the form of a downloadable VISITview and can be taken at anytime. Certificates of completion for NOAA employees can be obtained on the E-Learning Management System LMS

Create a directory to download the audio playback file (120 MB) from the following link: http://rammb.cira.colostate.edu/training/visit/training_sessions/mesoscale_convective_vortices/mesoscale_convective_vortices_audio.exe

After extracting the files into that directory click on either the visitplay.bat or visitauto.bat file to start the lesson. If both files are present, use visitauto.bat
Live VISIT teletraining (with an instructor leading the session). Check the VISIT Training Calendar to signup for teletraining. The session will last 75 minutes. This teletraining session uses the VISITview software, where a Windows PC with an Internet connection is needed.

Please follow the teletraining installation instructions to install the session

Talking points are available for this lesson and may be printed out to easily review the session in detail at any time.
