Fig. 5.

The behavior of the TEC, zonal and meridional components of the electric field, meridional component of the thermospheric wind, and the ratio n(O)/n(N₂) in the vicinity of the Greece earthquake epicenter obtained in the model GSM TIP. The left panel—calculation results at the setting of additional eastward electric field (solid lines). The right panel—calculation results at the setting of potential irregularity connected with vertical electric field (dotted lines), IGWs (solid thin lines) and the superposition of these two mechanisms (solid thick lines). Light circles—quiet conditions.
