Observation evidence for the entropy switch model of substorm onset
《Earth and Planetary Physics》2022年第2期161-176,共16页YunXiang Song ChuXin Chen 
supported by the National Natural Science Foundation of China(Grant No.NSFC41974204)。
The cause of substorm onset is not yet understood. Chen CX(2016) proposed an entropy switch model, in which substorm onset results from the development of interchange instability. In this study, we sought observationa...
