             abstract = "The aim of this study was to analyse the characteristics of an 
                         intense rainfall event that occurred in the Para{\'{\i}}ba do 
                         Sul river basin, southeast Brazil, in early 2000. Rainfall data 
                         from conventional meteorological stations and automatic weather 
                         stations, satellite images and datasets from the Climate Forecast 
                         System Reanalysis, National Centers for Environmental Prediction, 
                         were employed. After the arrival of a cold front in the state of 
                         S{\~a}o Paulo on 1 January, the first episode of the South 
                         Atlantic convergence zone (SACZ) of the year was established, 
                         lasting for 8 days. A dipole blocking pattern over the state of 
                         Rio Grande do Sul and Uruguay, with a cold core cyclone and a warm 
                         core anticyclone in the upper troposphere, weakened the westerly 
                         flow from the Pacific, favouring slow displacement of the SACZ. 
                         Intense moisture fluxes from the southern Amazon and tropical 
                         South Atlantic converged over southeast Brazil providing copious 
                         amounts of moisture for convective activity during the first 4 
                         days of January 2000. The most notable aspect of this event was 
                         the development of a cyclonic vortex embedded in the SACZ (CVES) 
                         in the Atlantic Ocean, with a warm core in the lower troposphere 
                         and a cold core at higher levels, which intensified rain in the 
                         study region. After the weakening of the blocking on 4 January, 
                         the CVES moved southeastward in the Atlantic. The symmetry of the 
                         CVES and conditions of the thermal gradient in the lower and 
                         higher troposphere suggest that the system presented subtropical 
                         characteristics during the first few days and became an 
                         extratropical cyclone later.",
