Cyclogenesis: Analysis Utilizing Geostationary Satellite Imagery
Dan Bikos, John Weaver, Roger Weldon, Toby Carlson, David Vallee
The objectives of this session are:
- Examine various conceptual models of cyclogenesis (basic, split flow, cold air, instant occlusion and in-stream)
- Learn to utilize a blend of conceptual models, satellite imagery, and NWP output in diagnosing cyclogenesis
This is a basic course. There are no prerequisites.
Training Session Options
LMS students - to begin the training, use the web-based video, YouTube 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 (96 MB) from the following link: http://rammb.cira.colostate.edu/training/visit/training_sessions/cyclogenesis/cyclogenesis_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
