Abstract content <br> &nbsp; (Max 300 words)

The mesosphere/lower thermosphere and thermospheric F-regions are dynamically coupled through thermospheric winds, tides and waves. The regular fluctuations in the earth's magnetic field on quiet days are caused
by dynamo-induced currents which flow in the ionosphere/thermosphere system.The ionospheric dynamo is driven by tidal winds from the lower atmosphere.
This paper presents simultaneous mesosphere/lower thermosphere and upper thermospheric region wind observations during a quiet magnetic period using
data from TIMED and CHAMP satellites.
