Results of GAIA simulation at South Africa at 13:42 LT on 8 January, 2011: (Left) altitude–latitude cross section of (top) meridional wind and (bottom) electron density perturbations and altitude–latitude variation of a magnetic field (taken from GAIA model) line with constant dip angle (~ 45°) at 250 km is also shown (black dotted lines) in these figures. (Right) Altitude profiles of standard deviation of (top) meridional wind and (bottom) electron density variations. The standard deviations are averaged over 20–30° S latitudes
