| Abstract: | A deep-water station is constructed for measuring the vertical component of the electric field on the surface-bottom base. A long-term experiment of measuring the vertical component in Lake Baikal is carried out. The measured signal fully reflects (due to the absence of the telluric component) variations in total flows in the range of periods from a few hours to tens of days. The coefficient of internal turbulent friction is estimated from the divergence between theoretical and experimental periods of the inertial flow. The detection of spectral maximums corresponding to variation periods of the hard component of solar radiation is the most important result of the present study. Possibly, this fact is direct evidence for the global electric circuit closure under suitable regional conditions. |
