We have begun to study the relationship between the activity of thunderstorms and ionospheric oscillation. This work was carried out during the period of 0 to 6 UTC of 10 November 2018 in the central region of Argentina. The Total electron Content (TEC)was computed from GNSS measurements provided by RAMSAC network stations and the atmospheric electrical activity data provided by the World Wide Lightning Location (WWLLN).We found that some TEC variations show oscillations with periodicities of 25-30 minutes and amplitude from 0.1 to 0.2 TECU; and sometimes oscillatory variations with periods of approximately 4 minutes and amplitudes below 0.1 TECU are superimposed. According to Lay et al, 2013, 2015;the first ones could be related with gravity waves, while the second one is could be considered acoustic waves.
