Abstrakt: Results of observations of traveling ionospheric disturbances (TIDs) by the multipath continuous HF Doppler sounding system operating in Taiwan are presented. We analysed one-year long period of measurements from April 2014 to March 2015 and investigated horizontal velocities and azimuths of propagation of medium scale traveling ionospheric disturbances (MSTIDs) with periods from 4 min to 60 min. Horizontal velocities range from ≈ 100 m s−1 to ≈ 300 m s−1 and MSTIDs propagate preferentially south-eastward in the local winter and preferentially northward in the local summer. The disturbances rarely propagate with azimuth in the range of 200–290◦ .
