pampero
From Glossary of Meteorology
A cold squally south or southwest wind over the pampas of the Argentine and Uruguay, which sets in with the passage of a cold front; the South American counterpart of a norther.
It is often accompanied by squalls, thunderstorms, and a sudden drop of temperature. The pampero seco is rainless; the pampero sucio brings a duststorm.
Compare minuano;
see zonda.
