| Resumo | Center for Weather Forecast and Climate Studies, National Institute for Space Reseach, Cachoeira Paulista, Brazil AB: Persistent weather conditions associated with synoptic systems and large scale features, which cause extreme precipitation events can reflect on monthly and seasonal values above or bellow climatological average. These cases cause intense damage in agriculture, cattle rising and urban areas. Periods of extreme dry conditions affect also the agriculture and disturb the water resources to hydroelectricity power. The La Plata Basin, in South America has large areas of agriculture in Brazil, Uruguay, Paraguay and Argentina and is also the location of Itaipu, the largest hydroelectricity power in South America. Therefore, monthly and seasonal precipitation wet and dry extremes in the region have a profound effect on the economy and society. The La Plata Basin extends from 15S to 37S and it is influenced by different precipitation regimes. The northern sector has a well defined annual cycle with maximum precipitation in summer and minimum in winter, while the southern sector has a uniform and less amount of precipitation during the year. The northern sector is affected mainly by the South Atlantic Convergence Zone and frontal systems, while the southern sector is influenced by frontal systems, cyclonic vortices and mesoscale convective systems. The objective of this study is to identify extreme precipitation in the two sectors of La Plata Basin and the associated atmospheric characteristics (seasonal, monthly and daily) in the period of 1979 to 2001. Observed precipitation is analyzed from GPCP data, atmospheric features from ERA40 reanalysis and SST from NOAA extended reconstructed SST. CPTEC/COLA AGCM T62L28 results are obtained from a 50 years climate simulation, initiated in 1950, and the same period of 1979 to 2001 is analyzed. Extreme precipitation months and seasons are selected based on Standardized Precipitation Index (SPI) to select extreme, severe and moderate precipitation cases. The extreme cases, both monthly and seasonal, display the opposite relation between northern and southern LPB sectors in both observations and model simulation. Large scale characteristics of anomalous SST, Sea Level Pressure and geopotential anomalies, as well the wind flow at low and high levels are analyzed for the monthly and seasonal extremes. Timeseries of daily precipitation anomalies for extreme monthly precipitation representing each season shows the extreme events and the associated synoptic and mesoscale systems.
