英文摘要 | Mesospheric winds from two longitudinal sectors at 53◦N latitude are combined to investigate quasi‐two‐days waves (Q2DWs) and their nonlinear interactions with tides. In a summer 2019 case study, we diagnose the zonal wavenumber m of spectral peaks at expected frequencies through two dual‐station approaches, a phase differencing technique (PDT) on individual spectral peaks and a least‐squares procedure on family‐batched peaks. Consistent results from the approaches verify the occurrences of Rossby‐gravity modes (m=3 and 4 at periods T=2.1d and 1.7d), and their secondary waves (SWs) generated from interactions with diurnal, semi‐diurnal, ter‐diurnal and quatra‐diurnal migrating tides. We further extend the PDT to 2012–2019, illustrating that Q2DWs exhibit significant interannual variability. Composite analysis reveals seasonal and altitude variations of the Rossby‐gravity modes and their SWs. The Rossby‐gravity modes maximize in local summer, whereas their 16hr and 9.6hr SWs appear more in winter. |
