DIFERENÇAS ASSOCIADAS À OSCILAÇÃO DECENAL DO PACÍFICO NAS RELAÇÕES INTERANUAIS DE PRECIPITAÇÃO NA AMÉRICA DO SUL E TEMPERATURA DA SUPERFÍCIE DO MAR
Resumen
Diferenças entre as fases fria e quente da Oscilação Decenal do Pacífico (ODP) nos padrões de correlação entre precipitação sobre a América do Sul e índices de temperatura da superfície do mar (TSM) nos oceanos tropicais adjacentes são analisados. Estes períodos são de 1948 a 1976 e de 1977 a 2002. Índices de TSM são usados para representar as variações de TSM no Pacífico equatorial leste (PEL), no Atlântico tropical norte (ATN), Atlântico tropical sul (ATS) e no Atlântico sudoeste (ASO). Diferenças marcantes nos padrões de correlação são notadas entre os dois períodos analisados.Citas
