Weather Seminar Videos 2020

Weather is a chaotic, turbulent, system. It's of critical interest to ocean voyagers, of course, and our understanding of it has advanced rapidly in recent years, thanks, in part, to dramatic advances in measurement, analysis, and communications technology. These advances have resulted in much better information available to the mariner in planning and executing a voyage.

CCA staged a full day of intensive weather seminars to help understand and make use of this information. The presentations were recorded and are offered here as voice-over-slideshow videos.  These will give you maximum information with least fuss.
