Focus Session: Anatomy of a Mid-latitude Storm

Anatomy of a Mid-latitude Storm: blue water or brown water, they affect us all

Anatomy of a Mid-latitude Storm Presentation (PDF)

Whether on a long trans-oceanic voyage, a run down the coast, visiting ports on the Great Lakes, or taking passengers on short day cruises, sailing vessels are exposed to the weather conditions produced by mid-latitude storms.  These conditions include strong winds, heavy rain (or snow), building seas, thunderstorms, and fog.  Mid-latitude (or extratropical storms) are common, large in scale, often develop quickly, can undergo explosive intensification, impact large areas of the ocean, and move rapidly. Fortunately, the formation, evolution of conditions, and possible impacts are better understood and more predictable than ever before.  This talk will walk through the evolution of an ocean storm from prediction (in advance of formation) to maturity using the forecast and analysis products that are available from NOAA.  Focus will be on anticipating conditions in various portions of the storm and heavy weather avoidance.
