Synthetic Imagery in Forecasting Severe Weather

Dan Bikos and Dan Lindsey


This training session is part of a series that focuses on applications of synthetic imagery from the NSSL 4-km WRF-ARW model. In this training session we'll consider applications of the synthetic imagery towards severe weather events. The primary motivation for looking at synthetic imagery is that you can see many processes in an integrated way compared with looking at numerous model fields and integrating them mentally.

This is an experimental GOES-R Proving Ground Product designed to foster GOES-R readiness.

This session was updated in March 2015 to reduce the length from 50 to 30 minutes, and add some notes regarding the synthetic 4-km NAM-Nest imagery interpretation. The previous (50 minute) version contains more cases, and can be found below in the "References/Additional Links" section.


This is an intermediate course. It's recommended that you take the following training session first: Water Vapor Imagery Analysis for Severe Weather
