Resumen:
Using data from two Fabry-Perot Interferometers located in Cajazeiras (6º 53 '25 "S; 38º 33' 19" O) and in São João do Cariri (7º 23 '27 "S; 36º 31' 58" O) observe the occurrence of oscillations with periods of days in the equatorial thermosphere for the period from October to December 2010 and 2011. To verify the existence of these oscillations, fixed times were chosen on an observation night, the data used for zonal and southern wind are from 20h (Local Time-HL), with a time resolution of one hour. In parallel, data on temperature and ionospheric parameters hmF2 and FoF2 observed through measurements of the ionosphere located at INPE-Fortaleza were analyzed, as well as magnetic activity data for the same period of wind data. The main characteristics found in the 2010 and 2011 wind fields were: Amplitude between 19.76-38.78m / s and 17.68-2.51m / s, for zonal and southern wind data, respectively, for the year 2011. The analysis of the ionospheric and magnetic activity parameters presented the same spectral characteristic observed in the zonal and southern wind data, suggesting a cause-effect mechanism.
