Abstract

The transient behavior of meridional moisture transport across the South American continent is examined with the reanalysis data provided by the European Centre for Medium-range Weather Forecasts (ECMWF). The results show clearly the effects of the valley between the Andes and the Brazilian Plateau in canalizing the southward moisture transport: an intense jet is episodically formed in this valley. The synoptic variability of this low-level jet and its relation to the large-scale atmospheric circulation are studied.
