Euroclydon (or in Latin: Euroaquilo) is a cyclonic tempestuous northeast wind which blows in the Mediterranean, mostly in autumn and winter. It is the modern Gregalia (Gregale) or Levanter. From the Ancient Greek word eurokludōn [εὐροκλύδων], from Euros (Eurus, meaning east wind) and either the Ancient Greek word akulōn (akylōn, meaning north wind), or kludon (meaning a surging wave from the verb kluzo meaning to billow) or the Latin word aquilō (aquilon). Euroclydon is not to be confused with the term nor'easter, which is a separate storm system that forms in the northeastern portion of the United States.
