Cyclogenesis: Analysis utilizing Geostationary Satellite Imagery

Other contributors: Brian Motta, Donald Moore, Stephen Jascourt, NWSFO BOX, SEW and MHX

Introduction

The objectives of this session are:

• Examine various conceptual models of cyclogenesis (basic, split flow, cold air, instant occlusion and in-stream).
• Learn to utilize a blend of conceptual models, satellite imagery, and NWP output in diagnosing cyclogenesis

Training Session Options:

• A.) Audio playback – This VISITview file contains recorded audio and annotations and can be taken at anytime. Certificates of completion for NOAA employees can be obtained through your Science Operation Officer or training point of contact.
