Resumen:
A dry, hydrostatic, three-dimensional primitive
equation model is used to evaluate the mechanical effect
of the Andes mountains on the South American low-level
flow (LLF). The model simulations reproduce the evolution
of a baroclinic wave over the continent under winter and
summer conditions. In both seasons as a consequence of the
interaction between the basic flow and the Andes, northerly
LLF was reproduced east of the Andes which resembles the
main characteristics of the observed flow. Moreover,
seasonal changes of cyclone activity have a significant
impact on the location of maximum LLF and its alignment,
which exhibits a NW-SE orientation during winter and more
meridional orientation in the warm season.
