Wind variations in the lower and upper thermosphere have been compared during a magnetic quiet period. 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. 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. The upper thermospheric winds from two time local sectors are observed to be faster than the lower thermospheric winds
