英文摘要 | With Van Allen Probes data, we present the observational support for whistler waves guided by the plasmapause based on a case study and statistical analyses. Due to the combined effects of inhomogeneous magnetic fields and plasma densities, whistler waves near the inner edge of plasmapause (plasmasphere side) will be guided by a HDD‐like (HDD, high density duct) density gradient, and tend to have very small wave normal angles (WNAs ≤20°). In contrast, whistler waves around the outer edge of the plasmapause (plasmatrough side) guided by a LDD‐like (LDD, low density duct) density gradient, tend to have quite large WNAs (≥∼60°). Moreover, the statistical analysis reveals the remarkably different properties of whistler waves around inner and outer edges of plasmapause. We suggest that the plasmapause density gradients may play a significant role in the distribution of whistler waves. |
