Introduction


The objective of this session is to better understand and utilize techniques for predicting the risk of convective downbursts using GOES sounder derived product data.

Training Session Options


NOAA/NWS students – to begin the training, use the web-based videoYouTube video, or audio playback options below (if present for this session). Certificates of completion for NOAA/NWS employees can be obtained by accessing the session via the Commerce Learn Center

  1. 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.

    Create a directory to download the audio playback file (32 MB) from the following link: http://rammb.cira.colostate.edu/training/visit/training_sessions/convective_downbursts/convective_downbursts_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

  2. Live VISIT teletraining (with an instructor leading the session). Check the VISIT Training Calendar to signup for teletraining. The session will last 60 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
