摘要:Based on the Van Allen Probe A observations from 1 October 2012 to 31 December 2014, we
develop two empirical models to respectively describe the hiss wave normal angle (WNA) and amplitude
variations in the Earth’s plasmasphere for different substorm activities. The long-term observations
indicate that the plasmaspheric hiss amplitudes on the dayside increase when substorm activity is
enhanced (AE index increases), and the dayside hiss amplitudes are greater than the nightside. However,
the propagation angles (WNAs) of hiss waves in most regions do not depend strongly on substorm
activity, exc
