 note = {P(論文), A terdiurnal 8hr period component is often observed in the radar and optical measurements of wind and temperature field at mesospheric heights. This might be either a global tidal wave of the 3rd harmonics of diurnal tide or locally confined gravity wave component or normal mode Lamb waves. Observationally, it has been found that in winter it is more evident and stable with longer vertical wavelength than in summer. Here, a brief overview is given in view of the latitudinal comparison of modeled and recently observed terdiurnal components, mostly at higher latitudes which might reflect higher order modes and relevant generation mechanism either by solar direct drive or by non-linear interaction or by local agent.},
