| Research Abstract |
Characteristics of ionospheric disturbances were studied by analyzing data of ground-based observations and satellite in-situ measurements. In this study, ionospheric disturbance which often appears during a solar minimum period was investigated in detail. I found that thermospheric winds would play an important role for the generation of the ionospheric disturbances. I also investigated characteristics of ionospheric disturbance observed following an great earthquake. It is found that both acoustic waves and gravity waves caused the ionospheric disturbances.
