Lightning Meteorology I examines electrification and cloud-to-ground (CG) lightning activity in typical warm season thunderstorms, both isolated storms and mesoscale convective systems. The broad objective of this teletraining course is to utilize CG lightning data in nowcasting / forecasting these storms.
Specific course objectives are:
- to gain a basic understanding of the ice-ice collisional charging mechanism
- to know the gross distributions of electrical charge in thunderstorms
- to understand how charge distributions control the production of negative and positive CG strikes (-CGs and +CGs
- to identify minimum thresholds in radar reflectivity and satellite cloud top temperature associated with CG lightning
- to use -CGs and +CGs to monitor storm lifecycle and convective and stratiform precipitation
- to integrate lightning data with sounding, satellite and radar data
This is a basic 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
- 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.
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 (30 MB) from the following link: http://rammb.cira.colostate.edu/training/visit/training_sessions/lightning_meteorology_1/lightning_meteorology_1_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.
