Numerical Simulation of the Influence of the may 2-3, 2010 Geomagnetic Storm on HF Radio-Wave Propagation in the Ionosphere

摘要

This study is devoted to HF radio wave propagation in the ionosphere during the May 1-3, 2010 geomagnetic storm. The research results were obtained by using two models, namely, the GSM TIP environment model developed at WD IZMIRAN and the radio-wave propagation model developed at I. Kant BFU. For certain selected frequencies we show the effect of the geomagnetic storm on the radio wave propagation. We give examples of a HF radio-wave path in the channels between the F-1 and F-2 layers of a high-latitude ionosphere and the F-2 and F-3 layers of a lowlatitude ionosphere. Characteristics of these layers may significantly affect the interpretation of the oblique sounding ionograms.
