Short summary

Using model–data analysis we emphasize a new result – formation of the positive daytime disturbances in foF2 and TEC at middle and low latitudes due to n(O)/n(N₂) enhancement during the recovery storm phase. The spatial extent of this phenomenon depends on the longitudinal sector. The positive disturbances in the electron content at heights of 800–20 000 km at high latitudes can appear simultaneously with the negative disturbances in TEC and foF2 due to electron and neutral temperature heating.
