This lesson presents some of the key characteristics of Mesoscale Convective Systems(MCS). These include MCS initiation, synoptic scale pattern recognition and parameter evaluation, precipitation distribution, and movement. The objectives of this teletraining class are to illustrate how forecasters can better predict MCS development and evolution. These objectives are directly beneficial to forecasters because they apply them to operations. Specifically, these benefits can help forecasters anticipate potential heavy rain situations and severe thunderstorm development often associated with MCSs.


This is a basic course. There are no prerequisites.
