摘要
综述和介绍了由TIROS—NOAA系列卫星资料制定高纬沉降粒子能流和电离层积分电导经验模式的方法,绘制了不同粒子沉降活动的Pedersen和Hall电导在磁纬-磁地方时坐标内的等值线分布图.同时给出了不同季节内受太阳电磁辐射控制的电导等值线分布.具体地分析了电导经验模式与磁层-电离层耦合过程的内在联系。
An empirical model of height-integrated Pedersen and Hall conductance inferred from the TIROS-NOAA satellite dare are introduced and reviewed.The contours of both Pedersen and Hall conductance are drawn with the magnetic latitude-magnetic local time coordinates between 45°-90°GM and 0-24 MLT for discrete levels of particle precipitation. Similar contours of conductance controlled by solar irradiation in different seasons are also shown with same coordinates but for 9°-90°GM and 0-24 MLT. The internal relationship between the magnetosphere-ionosphere coupling and conductance model is investigated too.
