| Zusammenfassung |
| We investigate propagation directions and horizontal velocities of gravity waves (GWs) in low-latitude ionosphere.
GWs are observed by the multi-point continuous Doppler sounding system installed in Taiwan (24°N 121°E).
Based on measurements over one year, the seasonal dependence of GWs properties is investigated.
Compared to the mid-latitude observations, no distinct seasonal dependence of GWs' directions is observed.
The propagation between west and south-west directions was not observed.
Typical observed horizontal velocities are in the range from 100 m/s to 200 m/s. |
