Resumen:
An estimation of the ionospheric wave
activity seasonal variability, derived from several years
ofFORMOSAT 3/ COSMIC GPS (Taiwan's Formosa Satellite Mission
3/Constellation ObservingSystem for Meteorology - Global
Positioning System) radio occultation electron density datais
presented. A systematic enhancement at the eastern side of the
Andes range with respect tothe western side is observed. A
fitting method to remove the wavelike component from eachmeasured
profile and estimate the wave activity is applied. The
differential effect introducedby the action of orography on the
generation to the eastern side of the Andes of mountainwaves
mainly during wintertime with respect to summertime deep
convection waves, or evensecondary waves, is analyzed.
