| Resumo | The Andes mountain range has an important influence on the atmospheric currents in South America. Part of the trade-wind is deflected southward by the mountain barrier and form a low level wind current that extends from Amazon region to the north of Argentina and adjacent areas. Sometimes the wind velocity in this current is so high that can characterize as a Low Level Jet (LLJ). The mean wind speed in the LLJ region is around of 9 m/s during the summer mouth, but it is not constant. There is a large diurnal variation, having a maximum at night time that can exceed 15 m/s. The LLJ is responsible for the transportation of large amounts of heat and humidity from Amazon region to severe weather systems in downstream LLJ areas. There are many proposed theories to explain the LLJ mechanism, including inertial oscillation due to frictional decoupling at night, baroclinicity produced by the inclined boundary layer over the slope terrain, large scale baroclicity, interaction with upper-level jets, etc. In this study, the South America LLJ is investigated from the point of view of eddy kinetic energy. Four terms of Eddy Kinetic Energy tendency are analysed: The Ageostrophic flux converge (AFC), the Baroclinic conversion (BRC), the Barotropic conversion (BRT) and Kinetic Energy Convergence (KEC). These terms were calculated using meteorological fields from Global NCEP/NCAR Reanalysis, which were performed with the inclusion of high-resolution data in the period from January to February of 2003, during the South American Low-Level Jet Experiment (SALLJEX). The results show that AFC has a strong diurnal variation and it is the dominant term in LLJ. The other components have significant influence too, especially in the longer time scale, from 2 to 5 days.In general the BRC and BRT modules the LLJ intensification, indicating influences from large scale systems. |
