                         days have been observed in the meteor radar zonal wind at Cariri 
                         (7.4°S, 36.5°W), in the ionospheric minimum virtual height h'F and

                         reveal that the 34-day oscillation was observed for all of these 
                         data during the period from March 1 to 11, 2005. From the 
                         characteristics of the downward phase propagation (wavelength of 
                         \∼40 km), longitudinal and latitudinal extension, we 
                         conclude that this oscillation must be a 3.5day Ultra Fast Kelvin 
                         (UFK) wave. This is the first report of clear evidence of 
                         propagation of a UFK wave from the stratosphere to the ionosphere. 
                         The UFK wave could have an important role in the day-to-day 
                         variability of the equatorial ionosphere evening uplift.",
