Advanced Scatterometry (ASCAT) plots derived from MetopB and MetopC, above, shows a pulse of winds associated with a Gulf of Tehuantepec wind event. Gales are widespread, and winds up to 45 knots are plotted. When Tehuano Gap Winds occur in clear skies (as in this example), the effect on the sea state can... Read More
