Regional and Mesoscale Meteorology Branch

Introduction:

Learning Objectives:

1. To learn what a regional satellite cloud composite is.
2. To find out what types of cloud composites can be created.
3. To find out how cloud composites fit into the forecast process.

Background:

This module reflects how one can create and use cloud composites on a regional scale to assist with everyday forecasting tasks. Cloud composites refer to a shorter time span than cloud climatology. This module highlights simple techniques used to create the cloud composites and regional applications used to visualize weather patterns – all from the diurnal geostationary satellite.

Training Session Options:

LMS students – to begin the training, use the Web-based Video or Audio Playback options below.
Note: Be sure to have your speakers on and the volume loud enough to hear the presentation.

1. Web-based Video training session
2. Audio playback – This VISITview file contains recorded audio and annotations and can be taken at anytime.

   Create a directory to download the audio playback file (it is about 59 MB in size) from the following site:
   ftp://rammftp.cira.colostate.edu/SHyMet/course_materials/forecasters/clim_shymet_dec2010.exe
   OR
   ftp://ftp.ssec.wisc.edu/visit/audio/clim_shymet_dec2010.exe

   After extracting the files into that directory click on the visitplay.bat file to start the lesson.
