The equatorial electrojet (EEJ) as well as the upper thermospheric zonal wind derived from CHAMP measurements exhibit a 4-peaked longitudinal structure that can be attributed to the eastward propagating diurnal tide with zonal wavenumber 3 (DE3). The former one is observed at 105 km altitude, the latter one at 400 km altitude. Yet both quantities exhibit the same DE3 inter-annual variation with a two year peak-amplitude modulation. Interestingly, DE3 is excited in the tropical troposphere in deep convective clouds and its influence on upper atmospheric parameters was not anticipated before. In this study we're going to present the CHAMP observed DE3 amplitudes in the EEJ and zonal wind and compare it to the DE3 zonal wind amplitudes in the mesosophere lower thermosphere and at 400 km altitude calculated with a physics-based empirical model based on Hough Mode Extension fits to TIMED tides. Further attention will be given to other nonmigrating tides such as the eastward propagating diurnal tide with zonal wavenumber 2 (DE2).
