                         driven by the 2-day wave in the tropical MLT region has been 
                         investigated. The problem is studied from an observational point 
                         of view. Three different types of data were analyzed in order to 
                         detect and extract the 2-day wave signals. The 2-day wave event 
                         during the period from 1 December 2002 to 28 February 2003 was 
                         identified in the neutral winds by radar measurements located at 
                         four tropical stations. The 2-day variations in the ionospheric 
                         electric currents (registered by perturbations in the geomagnetic 
                         field) and in the F-region electron densities were detected in the 
                         data from 23 magnetometer and seven ionosonde stations situated at 
                         low latitudes. Two features for each kind of wave were 
                         investigated in detail: the variation with time of the wave 
                         amplitude and the zonal wave number. The results show that the 
                         westward propagating global 2-day wave with zonal wave number 2 
                         seen in the ionospheric currents and in F-region plasma is forced 
                         by the simultaneous 2-day wave activity in the MLT region. The 
                         main forcing agent in this atmosphere-ionosphere coupling seems to 
                         be the modulated tides, particularly the semidiurnal tide. This 
                         tide has a larger vertical wavelength than the diurnal tide and 
                         propagates well into the thermosphere. The parameter that appears 
                         to be affected, and thus drives the observed 2-day wave response 
                         of the ionosphere, is the dynamo electric field.",
