abstract = "In the past decade, understanding of the day-to-day variability of
the ionosphere induced by waves propagating from bellow has
considerably been advanced. More recently, several studies have
pointed out that the secondary waves arising from the nonlinear
interaction between tides and planetary waves could significantly
impact the ionosphere. From the meteor radar wind at Cariri
(7.4°S, 36.5°W) and ionossonde measurements at Fortaleza (3.9°S,
38.4°W) we investigated the presence and effects of secondary
waves in the Brazilian equatorial MLT and ionosphere. We found an
evidence of the nonlinear interaction between an ultra-fast Kelvin
wave and the diurnal tide in the MLT wind. We identified a 1.3-day
secondary wave arising from this interaction and found it to
propagate upward with a relatively long vertical wavelength ( 44
km), which may allow it to penetrate into the ionosphere. From the
ionossonde measurements at Fortaleza we found indications of the
modulation of the F-layer height by the 1.3-day secondary wave. In
this paper, we will present and discuss details of this study.",
