Descripción
Global maps of potential wave energy per unit mass, recently performed with the Global Positioning System (GPS) Radio Occultation (RO) technique and different satellite missions (CHAMP and SAC-C since 2001, GRACE and COSMIC since 2006) revealed in Argentina, at the eastern side of the highest Andes Mountains, a considerable wave activity (WA) in comparison with other extra-tropical regions. The main gravity wave (GW) sources in this natural laboratory are deep convection (mainly during late Spring and Summer), topographic forcing and geostrophic adjustment. The mesoscale numerical WRF (Weather Research and Forecasting) 2.1.2 model was used to simulate the atmospheric parameters during two representative RO events showing apparent intense WA in this region. The significance of the relative position of the RO lines of sight, the line of tangent points and GW phase surfaces during each event is discussed in relation with the apparent WA detected. The GPS RO technique may not be by itself reliable enough to quantify and locate WA of single events. Nevertheless, it should be considered a useful tool to observe the global WA from statistical studies. We also discuss the relative contribution of high and medium intrinsic frequency mountain waves regularly observed, coexisting with inertio gravity waves, their origin and propagation characteristics. © 2009 COSPAR.
