中性风对赤道电离异常的影响
The effect of neutral wind on the Equatorial Ionization Anomaly
摘要
Abstract
Using the electron density in topside ionosphere inferred from GRACE satellite observations during medium-high solar activities,variations of Equatorial Ionization Anomaly(EIA)with local time and longitude were studied.Furthermore,the effect of neutral wind on the EIA development was investigated.The results show that the variation of EIA strength depends on local time and longitude,which is similar with the longitudinal variations of plasma bubble.EIA strength is mainly related to the electron density above the trough,and relationship between EIA strength and density above the trough also depends on local time and season.Neutral wind plays an important role in the development of EIA.关键词
