SALLJEX project description

South American Low-Level Jet Experiment


The South American Low-Level Jet Experiment (SALLJEX), a component of the CLIVAR/VAMOS program, is an internationally coordinated effort in order to contribute to the understanding of the role of the South American Low-Level Jet in moisture and energy exchange between the tropics and extratropics and related aspects of regional hydrology, climate and climate variability.


The goals are to improve short and long term prediction by obtaining an improved temporal and spatial structure description of the low-level jet, evaluate the veracity of numerical representation of the low-level jet, and determine improvements of the initial state representation and model parameterizations required to improve prediction .
