An information-theoretic approach for detecting causality and information transfer is used to identify interactions of solar activity and interplanetary medium conditions with the Earth's magnetosphere-ionosphere systems. A causal information transfer from the solar wind parameters to geomagnetic indices is detected. The vertical component of the interplanetary magnetic field (Bz) influences the auroral electrojet (AE) index with an information transfer delay of 10 min and the geomagnetic disturbances at mid-latitudes measured by the symmetric field in the H component (SYM-H) index with a delay of about 30 min. Using a properly conditioned causality measure, no causal link between AE and SYM-H, or between magnetospheric substorms and magnetic storms can be detected. The observed causal relations can be described as linear time-delayed information transfer.
一种用于检测因果关系和信息传递的信息论方法被用于识别太阳活动和行星际介质条件与地球磁层-电离层系统之间的相互作用。检测到从太阳风参数到地磁指数的因果信息传递。行星际磁场（Bz）的垂直分量以10分钟的信息传递延迟影响极光电集流（AE）指数，并以约30分钟的延迟影响由H分量对称场（SYM-H）指数测量的中纬度地磁扰动。使用经过适当条件设定的因果关系度量，未检测到AE与SYM-H之间或磁层亚暴与磁暴之间的因果联系。观测到的因果关系可描述为线性时延信息传递。
