摘要
本文利用欧洲非相干散射雷达数据,分析研究了电离层不同等离子体参量对大气重力波的响应之间的关系.应用这种关系,发展了一种在垂直于地磁场的电场可以忽略等简化假设下,由电子密度和离子沿场速度的同时测量数据,反演求解较高(约250km以上)F区中引起TID的重力波传播参数的方法.用此法对一典型TID事件进行分析计算,所得结果与全波解数值研究结果很好符合.
Relationships between ionospheric responses to atmospheric gravity waves in different plasma quantities are investigated with the help of European Incoherent Scatter radar data. Making use of the relationships and the simultaneous measurements of electron densityand field-aligned ion Velocity, an inversion method is developed under the assumptions of a negligible electric field perpendicular to the geomagnetic field and some others to determine the propagation parameters of GW's inducing TID's in the higher F-region (above about 250km). This method is utilized for a typical TID event and the result is in good agreement with that obtained by numerical studies of full-wave solution.
