| Abstract | O verão de 2003/2004 foi bastante chuvoso na região central do Brasil (Regiões Sudeste e Centro-Oeste, e o sul da Região Nordeste), posicionando-o entre os cinco verões mais chuvosos dentro dos últimos 45 anos. Foram observados 5 episódios da Zona de Convergência do Atlântico Sul (ZCAS) altamente influenciados pelas ondas intrasazonais que predominaram na atmosfera do planeta. Neste trabalho foram utilizadas anomalias normalizadas diárias de altura geopotencial em 200hPa ), Radiação de Onda Longa Emergente (ROLE) e chuva interpolada sobre a América do Sul para diagnosticar as relações entre a Oscilação de Madden-Julian, o padrão de teleconexão Pacific South American (PSA) e a ZCAS. Os resultados mostraram que em dezembro, a OMJ esteve associada ao PSA criando condições de grande escala favoráveis ao desenvolvimento de aglomerados convectivos que atingiram a região sul do Brasil. Em janeiro, a OMJ esteve associada a um trem de onda subtropical de característica zonal, que favoreceu a formação de três episódios da ZCAS. Em fevereiro, assim que a convecção associada à OMJ retorna à Indonésia, o PSA volta a se estabelecer mantendo uma situação de grande escala favorável à formação e sustentação de dois episódios da ZCAS. ABSTRACT: The 2003/2004 austral summer was very rainy in the central portions of Brazil (Southeast and Central-West Regions, and southern NEB) ranking it among the five rainiest summer from the last 45 years. Five episodes of South Atlantic Convergence Zone (SACZ) occurred during this summer highly influenced by the intraseasonal waves that prevailed over the planet. This work has used daily normalized anomalies of geopotential heigh at 200 hPa (NCEP/NCAR Reanalysis) and Outgoing Longwave Radiation (ROL), plus interpolated rain over the whole South America to diagnoses the relationships among the Madden-Julian Oscillation (MJO), the Pacific South America (PSA) pattern of teleconnection and the SACZ. The results have shown that during December the MJO has been associated to the PSA, maintaning favorable large scale conditions to the occurrence of convective clusters that stroke the southern Brazil. In January, the MJO has been associated to a zonal wave train located almost entirely in the subtropical belt. This wavetrain has maintained appropriated conditions to the development of three SACZ episodes. In february, as soon as the MJO convective phase has returned to the Indonesian region after had traveled the globe around the equator, the PSA returns to keep a large scale pattern that actively participate in two others SACZ episodes. |
