Abstract
The responses of low latitude ionospheric drifts to three levels of geomagnetic activity for high and low solar activities have been investigated by analyzing the plasma drifts data obtained by Meridian Project Hainan station (19.5°N, 109.1°E) during 2003-2016. Results show that the daytime dominant westward drifts do not change much with magnetic activities in all seasons. The near sunrise and nighttime dominant eastward drifts decrease with the increase of magnetic activities and are more significantly in equinox, less in summer. The daytime weakly upward drifts are independent of magnetic activities and seasons. The enhanced sunset upward decrease with magnetic activities only in equinox. The vertical drifts before midnight are suppressed in equinox and reversed in winter for magnetic disturbance, but have no obvious response in summer. The downward drifts from midnight to sunrise are basically reduced with the increase of the magnetic activities in all seasons. The effects of magnetic and solar flux on drifts in Hainan follow closely with Jicamarca. However, there are some differences in amplitude and phase, which may be caused by difference in solar cycle, geographical and detection techniques.
