Abstract利用2003-2016年期间子午工程海南站(19.5°N,109.1°E)数字测高仪观测到的电离层等离子体漂移数据,分析了高低两种太阳活动条件下纬向和垂直向漂移对近磁静、中等磁扰和强磁扰三种地磁活动水平的响应特性.结果表明:日间纬向漂移各季节均以西向为主,随地磁活动无明显变化,白天日出附近和夜间漂移在各季节均以东向为主,随地磁活动增强而减弱,减弱程度在分季最大,在夏季最小;日间垂直漂移在零值附近变化,且不受地磁活动和季节影响,日落附近漂移仅在分季受到地磁活动的抑制,午夜前垂直漂移在分季受到抑制,在冬季因强磁扰而反向,夏季无明显规律,子夜至日出后垂直漂移在各季节随地磁活动增强而减小.与赤道区Jicamarca相比,两地漂移对地磁活动的响应相近,但在幅度和相位上存在差异,这可能是两地区的地理位置、背景电场和风场结构等不同造成的.
Other AbstractThe 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.
