GOES-R Cyclogenesis Potential Vorticity Concepts

Introduction

This module is part of the satellite foundational course for GOES-R (SatFC-G). This particular module covers potential vorticity concepts applied to extra-tropical cyclogenesis.

Learning objectives:

1. Review the concept of “potential vorticity (PV) thinking” and how it related to cyclogenesis
2. Discuss satellite identification of “PV anomalies”
3. Discuss which ABI bands can be helpful in viewing PV anomalies
4. Examine a case study

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 Learning 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.

2. YouTube video:

3. Download video (recommended for low-bandwidth users) – This is an audio playback version in the form of an Articulate Presenter video and can be taken at anytime.

   Create a directory to download the video file from the following link: http://rammb.cira.colostate.edu/training/visit/training_sessions/goes_r_cyclogenesis_potential_vorticity/goes_r_cyclogenesis_potential_vorticity_articulate.zip

   After extracting the files into that directory click on either the presentation.html OR index.html file and the video will begin to play in your browser.

Original Pre-Launch Version

This version of the training module debuted in the Fall of 2016 which included Himawari and pre-GOES-R era GOES imagery. Formats include:

• Articulate Presenter Video
• Articulate Download (zip file)
• Youtube video
