Summary: | In this paper our attention is focused on relations between radio signal
propagation characteristics and temperature changes in D-region after solar
X-flare occurrence. We present temperature dependencies of electron plasma
frequency, the parameter that describes medium conditions for propagation of
an electromagnetic wave, and the refractive index which describes how this
wave propagates. As an example for quantitative calculations based on
obtained theoretical equations we choose the reaction of the D-region to the
solar X-flare occurred on May 5th, 2010. The ionospheric modelling is based
on the experimental data obtained by low ionosphere observations using very
low frequency radio signal. |
