Diurnal variation of gravity wave type oscillations at midlatitudes in the ionospheric F region.
Original language description
We investigate the short-term fluctuation in the period range from 15 to 180 minutes in the electron density variations of the F region ionosphere. Electron density profiles obtained at the ionospheric stations of Pruhonice (49.9 N, 14.5 E) and Ebro (40.8 N, 0.5 E) at five minute time sampling have been used for this analysis. The diurnal changes of the activity of the acoustic gravity wave fluctuations (AGW) show a clear enhancement during and several hours after sunrise. The periods of such AGW's areabout 60 to 75 minutes and these waves propagate vertically through the ionosphere from from a source located at an altitude of 180 - 220 km. The most likely source for these events seems to be passage of the Solar terminator.
