Abstract

A "friagem" is a cold front which moves northward from southern Brazil to the Caribbean coast of South America. A set of composite satellite pictures (2) of the American sector of the southern hemisphere as well as the recorded of daily temperatures in a secondary forest near Manaus are presented. The low temperatures and strong winds associated with this phenomenon have a profound effect on the environment of Amazonia.

Resumo

No período de 3 a 14 de julho de 1969 a temperatura do ar foi medida em duas altitudes em uma capoeira da Reserva Florestal Ducke, Estrada Manaus - Itacoatiara (Km — 26). Do dia 10 até o dia 13 a temperatura foi influenciada por uma onda fria (friagem) caida no local e cujo desenvolvimento foi observado por satélite (fotografado). No início da friagem, a temperatura baixou nos dois níveis até 15°C voltando após algumas horas a apresentar variações devido ao movimento turbulento das camadas de ar.
