                         Although there are many works in the literature about the 
                         occurrence of extreme precipitation events in the southern South 
                         America, its relationship with the Low-Level Jet East of the Andes 
                         (SALLJ) is less studied. The aim of this study is to investigate 
                         the relationship of the daily extreme precipitation events with 
                         the position, intensity and duration of the SALLJ. Hereby, it 
                         concentrates on the components of the circulation, convection and 
                         moisture transport of the Amazon region towards the south of the 
                         continent, focusing especially on the La Plata basin region. 
                         Precipitation data from approximately 1500 surface stations and 
                         the reanalysis gridded data of the NCEP-NCAR for the period 
                         November to March, from 1979 to 1998, are used in this study. An 
                         extreme event is defined here when daily rainfall exceed the 95th 
                         percentile. In order to identify the SALLJ events the Bonner 
                         criterion 1 was applied in site 20°S-60°W. The related dynamic 
                         aspects to the patterns observed in the atmospheric circulation 
                         since the surface up to high tropospheric levels for the 
                         simultaneous and unbalanced days of occurrence of extreme 
                         precipitation events and of the SALLJ had been analyzed through 
                         composites of diverse anomaly fields. It was found that the 
                         extreme events and the SALLJ are well correlated with each other 
                         as well as with high and low frequency systems from 
                         midlatitudes..",
