SINOPSIS

Energy of solar eclipses significantly influences the variation of geophysical fields and leads to a change of processes in the subsystems of the Earth and to disturbance of the existing interactions between them. Observations of each solar eclipse allow specifying related physical processes and their impact on the radio waves propagation in the troposphere. The effects of the solar eclipse are widely discussed in the scientific world, but at present day the studies of radio wave propagation in the troposphere during a solar eclipse are absent. The results of observations of the interaction between solar eclipses and levels of microwave radio signals in a variety of conditions, including land and sea over-the-horizon radio communication, as well as a geostationary satellite to Earth radio path and others are presented in the paper. In order to analyze conditions that accompany these phenomena, the method of superposed epochs comprising correlation, spectral and dispersion analysis of measured values is used. It is shown that the signal level change occur in the direction of increasing in most cases. The presented study extends the knowledge about the influence of the Sun on the propagation of radio waves in the atmosphere.
