Resumen:
The gravity wave activity on a global scale between 10 and 27 km was analyzed by using temperature profiles retrieved from GPS occultation events detected with SAC-C and CHAMP satellites. Examples of its variability with altitude, longitude, latitude and time are presented for different wavelength ranges. A particular attention is given to gravity wave generation in the Andes Range region, in connection with the forcing of the mean wind by the mountains, and in the equatorial region, in possible connection with convective activity. A clear signature, possibly related to mountain wave generation, is seen above Andes mountains, between 30 and 40S. It is also appreciated the global enhanced wave activity in equatorial regions during the winter hemisphere.
