Travelling ionospheric disturbances in the ionized regions of the earths atmosphere have been investigated using a CW doppler phase-path sounding array. A description of wave characteristics such as periods and wavelengths for medium scale TIDs is given. An apparent correlation between TIDs and occurrence of sporadic E was examined in the light of internal atmospheric gravity wave theory. The results of the present investigation were compared with those of earlier results. It can be concluded from this study that near the solstices, TIDs in both hemispheres travel in approximately the same direction, away from the pole. Near the equinoxes, TIDs in the Northern Hemisphere travel approximately in the westward direction, while those in the Southern Hemisphere travel eastward.
