Numerical modeling of the high-latitude F-layer anomalies

Abstract

The results of a detailed numerical study of the behaviour of the convective polar ionosphere are presented. The developed theoretical model produces three-dimensional distribution of electron density, electron and ion temperature. The effects of auroral particle precipitation on the density and temperature structures are studied for winter and low solar activity conditions. The high-latitude ionospheric features, such as ‘the tongue of ionization’, ‘the main trough’, ‘the polar ionization peak’, ‘the auroral ionization peak’, ‘the high-latitude ionization hole’, ‘the tongue of electron temperature’, ‘the high latitude minima of electron temperature’, and ‘the ion temperature hot spot’ are obtained from calculations.
