%X Partial reflection measurements at middle latitudes in the vicinity of Kharkiv have been used to study the effect of strong thunderstorms on parameters of the ionospheric D-region. It is shown that during thunderstorms the electron number density *N* in the lower D region (*z* < 70 km) often increases to *N* < 8·10^{3} cm^{-3}; while in the higher part (*z* > 80 km ) no changes occur. Possible variations of the electron-molecule collision frequency are investigated.
