                         driven by the 5-day Rossby W1 and 6-day Kelvin E1 waves in the low 
                         latitude MLT region has been investigated. Three different types 
                         of data were analysed in order to detect and extract the ~6-day 
                         wave signals. The NCEP geopotential height and zonal wind data at 
                         two pressure levels, 30 and 10 hPa, were used to explore the 
                         features of the ~6-day waves present in the stratosphere during 
                         the period from 1 July to 31 December 2004. The ~6-day wave 
                         activity was identified in the neutral MLT winds by radar 
                         measurements located at four equatorial and three tropical 
                         stations. The ~6-day variations in the ionospheric electric 
                         currents (registered by perturbations in the geomagnetic field) 
                         were detected in the data from 26 magnetometer stations situated 
                         at low latitudes. The analysis shows that the global ~6-day Kelvin 
                         E1 and ~6-day Rossby W1 waves observed in the low latitude MLT 
                         region are most probably vertically propagating from the 
                         stratosphere. The global ~6-day W1 and E1 waves seen in the 
                         ionospheric electric currents are caused by the simultaneous 
                         ~6-day wave activity in the MLT region. The main forcing agent in 
                         the equatorial MLT region seems to be the waves themselves, 
                         whereas in the tropical MLT region the modulated tides are also of 
                         importance.",
