| Abstract | The nonlinear interaction between tides and planetary scale waves contributes to the short-term variability of the MLT dynamics and is a pathway for the coupling between the neutral atmosphere and the ionosphere-thermosphere (I-T) system. By using MLT wind measurements carried out at Cariri (7.4oS, 36.5oW) and at Ascension Island (7.9oS, 14.4oW) we have investigated the nonlinear interaction between an ultrafast Kelvin wave (UFKW) and the diurnal tide. Along with the signature of an UFKW (∼0.25 cycle/day), we observed periodic oscillations in the zonal wind, at both Cariri and Ascension Island, consistent with the secondary waves generated via the nonlinear interaction between the UFKW and the diurnal tide (1 cycle/day). In addition, we observed the modulation of the diurnal tide amplitude in the zonal wind at the period of the UFKW. At Cariri only the 0.75 cycle/day secondary wave related to the difference between the frequencies of the diurnal tide (1 cycle/day) and the UFKW was observed. On the other hand, at Ascension, both secondary waves related to the sum (1.25 cycle/day) and difference (0.75 cycle/day) between the diurnal tide and UFKW frequencies were observed. The vertical structure of these periodic oscillations also exhibited distinct behavior. At Cariri, the 0.75 cycle/day secondary wave exhibited a well-defined vertical structure with downward phase progression, indicating upward propagation with vertical wavelength of 44 km. On the other hand, at Ascension, while the 0.75 cycle/day secondary wave did not exhibit clear phase progression, either downward or upward, the 1.25 cycle/day secondary wave exhibited downward phase progression, and then upward propagation, with vertical wavelength of approximately 20 km. In this paper we will present and discuss in more details the characteristics and possible impacts of the nonlinear interaction in the mesosphere-thermosphere-ionosphere system. | |||
