| Abstract | Este trabalho analisa as condições meteorológicas que levaram à ocorrência de uma intensa onda de calor na região subtropical da América do Sul, com temperaturas máximas superiores aos 40*C imediatamente à leste dos Andes, na última semana de Janeiro de 2003. Para isso, os termos da Equação Termodinâmica foram avaliados a partir de simulações numéricas realizadas com o modelo regional Eta/CPTEC. O forte aumento da temperatith foi provocado pelo aquecimento por compressão adiabática, produto da subsidência, e pelo aquecimento superficial imediatamente a leste dos Andes. A análise da Equação Ornega Quase-Geostrófica permitiu estabelecer que a subsidência de grande escala se deveu fundamentalmente ao avanço de uma crista de onda longa nos níveis meios da atmosfera. Além disso, as observações e as simulações numéricas apontam para a ocorrência de subsidência forçada (vento Zonda) a leste dos Andes, associada ao deslocamento de um cavado de onda curta imerso na crista de onda longa, à aproximação de uma frente fria e ao deslocamento para o sul da Baixa Termo-orográfica. Esse fato, muito pouco freqüente no verão, em combinação com os processos descritos anteriormente, explicaria a ocorrência de recordes históricos de temperatura no oeste da Argentina. ABSTRACT: This work analyzes the meteorological conditions that caused the occurrence of an intense heat wave over subtropical South America, with temperatures higher than 40°C immediately to the east of the Andes, during the last week of January 2003. To that purpose the terms of the thermodynamic equation were evaluated through numerical simulations performed with the Eta/CPTEC regional model. The strong temperature increase was caused by adiabatic warming (subsidence) as well as by the net positive surface heat fl ux, especially to the east of the Andes. The qualitative analysis of the Quasi-Geostrophic Omega Equation revealed that the large-scale subsidence was the result of the cold horizontal temperature advection and the advance of a wide ridge at midlevels. Additionally, the presence of forced orographic subsidence (Zonda wind) is evident from observations and numerical simulations in connection with the passage of a short trough immerse in the wider ridge, the approach of a cold front and the southward progress of the thermal-orographic low. Since this phenomenon is quite uncommon during summer, its incidence in combination to the other processes previously described would explain the occurrence of extreme maximum temperatures over western Argentina.. |
