摘要: The daily variations in ionospheric drift velocities are examined from incoherent scatter measurements at Millstone Hill. data with ∑ Kp > 24 behave differently those low magnetic activity and basically follow the convection pattern but have large day-to-day variations. influence of conjugate point is discussed, solar cycle conjunction geomagnetic Ionospheric currents calculated by using a semidiurnal neutral wind model good agreement ground-based magnetograms for activity, E region appears to be applicable only this case.
