abstract = "The Low Level Jet East of the Andes (LLJ) represents a mesoscale
circulation feature located to the East of the Andes, and which
maximum speed is on the first 2 km in the vertical. The LLJ brings
moisture from the Amazon basin into the La Plata basin, and seems
to be stronger in summer, producing rainfall in the southeaster
South American region. We present some results of the SALLJEX
field Campiagn of summer 2003, expl,aining some of the opbserved
features of the LLJ, as well as upper and low-level circulation
for seasonal means and SALLJ composites during the warm and cold
seasons. On the circulation characteristics, SALLJ composites
during the warm season show the enhanced low-level meridional
moisture transport coming from equatorial South America as well as
an upper level wave train emanating from the West Pacific
propagating towards South America. The intensification of the warm
season LLJ obeys to the establishment of an upper-level ridge over
southern Brazil and a trough over most of Argentina. The
circulation anomalies at upper and lower levels suggest that the
intensification of the LLJ would lead to an intensification of the
South Atlantic Convergence Zone SACZ later on, and to a
penetration of cold fronts with an area of enhanced convection
ahead at the exit region of the LLJ.",
