摘要：
Abstract: Results are presented from modeling the propagation of the auroral hiss from the region of its source to the ground and comparing it to observations. An analysis is performed of the conditions of propagation that explain the locality of the illuminated area of the auroral hiss observed on the ground. It is shown that quasi-electrostatic waves with random amplitudes, phases, and wave normal 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 could be responsible for the relatively small size of the illuminated area. © 2023, Allerton Press, Inc.
