Abstract :
This work studies variations of HF characteristics and ionospheric parameters recorded over mid-latitude paths of Russian East-Siberian region during magnetic storms on May 15, 1997, and September 24, 2006. The sharp wave-like changes of maximum observed frequencies (MOF) were recorded during the main phase of investigated storms. Assuming that observed MOF variations can be produced by ionospheric disturbances propagating from the northern to the southern latitudes simulation of HF propagation conditions was carried out.
