AbstractOndas quase estacionárias (OEs) são ondas que podem ser observadas no estado médio da atmosfera. Este trabalho visa mostrar o comportamento das OEs em fevereiro de 2005, quando houve ocorrência de intensa seca no sul, sudeste e centro-oeste do Brasil. Foram utilizados dados de geopotencial de reanálise NCEP-DOE e de precipitação do GPCP. Foi observada uma grande amplificação da onda 3 que atuou intensificando a circulação anticiclônica no sul da América do Sul, e esteve associada a um evento de bloqueio. ABSTRACT: Quasi-stationary waves can be observed in the mean state of the atmosphere. The objective of this study is to show the behavior of these waves during February 2005, when an intense drought occurred in southern, southeastern and central Brazil. NCEP-DOE reanalyses data and GPCP data were used in the study. A strong intensification of wave 3 was observed, which was related to the intensification of an anticyclonic circulation over southern South America and was associated with a blocking situation..
