Resumen:
An estimation of the ionospheric wave activity seasonal variability, derived from several years of FORMOSAT 3/ COSMIC GPS (Taiwan?s Formosa Satellite Mission 3/Constellation Observing System for Meteorology - Global Positioning System) radio occultation electron density data, is presented. A systematic enhancement at the eastern side of the Andes range with respect to the western side is observed. A fitting method to remove the wavelike component from each measured profile and estimate the wave activity is applied. The differential effect introduced by the action of orography on the generation, to the eastern side of the Andes, of mountain waves mainly during wintertime with respect to summertime deep convection waves, or even secondary waves, is analyzed.
