Аннотация

A numerical model of auroral hiss propagation from the region of its generation to the ground surface is developed for the interpretation of results from ground-based high-latitudinal VLF observations. The model includes modules describing the statistical properties of electrostatic whistler waves generated due to Cerenkov resonance at the heights of 6000–20 000 km, the propagation of these waves in the magnetosphere to the region of upper ionosphere (under 5000 km), which is filled with small-scale irregularities of electron concentration, the scattering of electrostatic waves from these irregularities into the transition cone, and further propagation of the waves through the lower ionosphere down to the ground surface. The modeling results agree with the observations.
