Using the data of the ionospheric vertical sounding in Almaty, the response of various parameters of the nighttime F layer to the passage of an atmospheric gravity wave, generated during the large magnetic storm on July 24-25, 2004, is studied. The analysis of the phase relations between the variations in the electron density at the F layer maximum ( NmF), the layer maximum height ( hmF), and the layer half-thickness showed that they are determined by the slope of the wave phase front. It is shown that the half-thickness of the layer changes in anti-phase with the variations in NmF2. The known fact that the amplitudes of variations in the critical frequencies of the F 2 layer are smaller than the amplitudes of electron density variations at fixed heights is explained.
