Other Contributors: Greg Byrd, Bill Bua, Jeff Waldstreicher
This is a more advanced session designed to build on the first VISIT Lake-Effect Snow 1 teletraining. The topics covered will include:
- Mesoscale Model limitations:
- Horizontal resolution
- Convective paramaterization schemes best for lake-effect snow
- Initialization / model spinup
- RUC characteristics
- Lake Aggregate Effects:
- Description of lake aggregate effects along with case studies to apply principles
This is an advanced course.
If you are not familiar with the basics of lake-effect snow please review the recorded audio version of the introductory VISIT Lake-Effect Snow 1 training session on your own.
Training Session Options
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 (90 MB) from the following link: http://rammb.cira.colostate.edu/training/visit/training_sessions/lake-effect_snow_2/lake-effect_snow_2_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
- Talking points are available for this lesson and may be printed out to easily review the session in detail at any time.
