Tehuano

From Glossary of Meteorology



Tehuano

A Spanish term frequently used to denote a burst of strong offshore (southward) wind, lasting a day or more, that blows from the Gulf of Mexico across the Gulf of Tehuantepec.

Tehuano events are associated with winter surges of cold air that spread southward from the United States across the Gulf of Mexico behind strong weather fronts. Tehuanos produce much local cooling of the gulf waters and frequently cause anticyclonic warm-core ocean eddies to form and propagate west-southwestward near 12°–14°N.
