Convective Cloud-top Cooling

Scott Lindstrom


This is training that focuses on cloud-top cooling (CTC), and it replaces previous training on UW Convective Initiation as that product has evolved. The most significant cloud-top cooling is inferred to be the most intense growing convection, and that cooling correlates well with future NEXRAD signals. Vertical cloud growth detected from satellite by cooling brightness temperatures is what CTC keys on.

  1. How clouds can give early convective information
  2. How does the UW Cloud-Top Cooling algorithm work
  3. Examples
  4. How can CTC be used in conjunction with synoptic and mesoscale awareness to anticipate future development in NEXRAD
This is an experimental GOES-R Proving Ground Product designed to foster GOES-R readiness.


This is an intermediate course. There are no prerequisites.

Training Session Options

NOAA/NWS students - to begin the training, use the web-based video, YouTube 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. 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. Also be sure that you are using a flash enabled browser.
  2. 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 (74 MB) from the following link:

    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

  3. Live VISIT teletraining (with an instructor leading the session). Check the VISIT Training Calendar to signup for teletraining. The session will last 45 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
