                         that show that the Low Level Jet East of the Andes (hereafter, 
                         LLJ) is responsible for most of the moisture and energy transport 
                         between these two basins, and the LLJ is a components of the South 
                         American Monsoon System. Studies using reanalises and other 
                         observational data sets have started to show some characteristics 
                         of the LLJ. A field experiment was implemented during the austral 
                         summer of 2003 to perform high resolution observations in the 
                         characteristics of the LLJ. A science team involving scientists 
                         from Brazil, USA, Bolivia, Argentina, Paraguay and Peru is working 
                         on the analysis of series of detailed and high resolution surface, 
                         upper-air and remote sensing observation, in order to answer this 
                         science question: What is the role of the LLJ on the moisture 
                         transport from the Amazon to the La Plata basins? More specific 
                         science issues include: the synoptic variability of the LLJ; the 
                         spatial structure and time variability from diurnal to 
                         intraseasonal time scales; the role of the of the LLJ in the 
                         intraseasonal variability of precipitation along the South 
                         Atlantic Convergence Zone; the role of the LLJ in the dynamics of 
                         the Mesoscale Convective Complexes over the La Plata Basin; the 
                         interannual variability of the LLJ; the dependence of the LLJ in 
                         relation to SST anomalies in the Pacific and Atlantic; the 
                         representation of the LLJ in atmospheric models; and the coupling 
                         between the occurrence or not of LLJ episodes and rainfall in the 
                         Andean region, east of the Andes, and southern Brazil-northern 
                         Argentina.The extension and upgrading of the current observational 
                         network will allow for better and more frequent surface and 
                         upper-air directed towards a better understanding of the LLJ, 
                         based on a combination of observation and monitoring of 
                         circulation and fluxes associated to the LLJ, complemented by 
                         regional and global models. Using observations from this field

                         NCEP we studied case studies, seasonal variability as well as 
                         interannual and interdecadal variability of the LLJ and its
