From AMS Glossary
(Also spelled popogaio.) A violent northeasterly fall wind on the Pacific coast of Nicaragua and Guatemala.
It consists of the cold air mass of a norte that has overridden the mountains of Central America and, being a descending wind, brings fine clear weather. Papagayos are most frequent and strongest in January and February, often lasting three or four days. They weaken between 7 and 10
and freshen again, sometimes to gale force, in the evening and early night.
