Frequency‐Dependent Responses of Plasmaspheric Hiss to the Impact of an Interplanetary Shock

Geophysical Research Letters, 2021
Plasmaspheric hiss waves are essential for the pitch‐angle scattering and precipitation of energetic electrons and interplanetary shocks may affect these waves.

Prompt responses of magnetospheric whistler-mode waves to solar wind dynamic pressure pulses

Frontiers in Astronomy and Space Sciences, 2023
Whistler-mode waves play a critical role in shaping the Earth’s radiation belts, and their spatiotemporal distribution is vital for forecasting and modeling geospace weather.

Nonlinear wave growth theory of coherent hiss emissions in the plasmasphere [PDF]

Journal of Geophysical Research: Space Physics, 2015
AbstractRecent observations of plasmaspheric hiss emissions by the Van Allen Probes show that broadband hiss emissions in the plasmasphere comprise short‐time coherent elements with rising and falling tone frequencies. Based on nonlinear wave growth theory of whistler mode chorus emissions, we have examined the applicability of the nonlinear theory to ...

An empirical model of the global distribution of plasmaspheric hiss based on Van Allen Probes EMFISIS measurements

Earth and Planetary Physics, 2020
Using wave measurements from the EMFISIS instrument onboard Van Allen Probes, we investigate statistically the spatial distributions of the intensity of plasmaspheric hiss waves.

Survey of ELF-VLF plasma waves in outer radiation belt observed by Cluster STAFF-SA experiment [PDF]

Annales Geophysicae, 2008
Various types of plasma waves have profound effects on acceleration and scattering of radiation belt particles. For the purposes of radiation belt modeling it is necessary to know statistical distributions of plasma wave parameters.

The interactions between ULF waves and cold charged particles in the Earth's magnetosphere

地球与行星物理论评, 2022
In the solar wind-magnetosphere coupling processes, many kinds of plasma waves can be excited in the Earth's magnetosphere including ULF waves, hiss waves, chorus waves, etc. Among these waves, ULF waves are featured by the lowest wave frequency (1 mHz～1

Scattering of energetic electrons through nonlinear cyclotron resonance with coherent whistler-mode hiss emissions [PDF]

, 2022
Recent observations have revealed that plasmaspheric hiss consists of many discrete waves called “hiss elements”. However, the interaction of energetic electrons (10 keV to several MeV) with the plasmaspheric hiss has only been simulated by the ...
