Key result
Modeling of auroral hiss propagation showed that quasielectrostatic waves form two wave beams in the meridional plane, and scattering at 800-1300 km altitudes can cause the observed locality.
Why the study?
The study was conducted to analyze propagation conditions explaining the locality of the auroral hiss illuminated area observed on the ground through modeling and comparison with observed results.

Comparison
Auroral hiss propagation modeling from the source region to the ground vs observed results
Design
Propagation modeling and observational comparison study
Scattering model may account for auroral hiss locality; leaves open need for in-situ validation before wider adoption.
We present the results of the auroral hiss propagation modeling from the source region to the ground and its comparison with the observed results. We analyzed propagation conditions explaining locality of the auroral hiss illuminated area observed on the ground. It is shown that quasielectrostatic waves with random amplitudes, phases and wavenormals directions representing the auroral hiss propagating to the ground form two wave beams in the meridional plane. The scattering of these waves at altitudes of 800–1300 km can cause the observed locality of the illuminated area.
