Paper Abstract

Diurnal variations of radio noise intensity (14.88 kHz) registered in Yakutsk in June 2009-2014 is 10 dB, March - 9 dB, September - 8.7 dB, December - 7.3 dB. Diurnal variations of intensity of radio station VLF signals, radio noise intensity and the number of lightning discharges in Yakutsk are compared. VLF noise variations in summer 5-10 UT defined local thunderstorm activity. The period 11-20 UT for receiving radio noise defined distant thunderstorm cells in Western Siberia, the territory between Hinggan, Buretsky and Stanovoy mountaines. Radio signals from these areas propagate in similar paths like signals Novosibirsk and Khabarovsk navaid stations. The attenuation variations from a solar activity minimum to the maximum are estimated. Taking into account the changes of propagation attenuation of 1.2 dB (signal Khabarovsk) from a minimum to a maximum of solar activity in July, the power of VLF radio noise at a minimum on 7.6 dB greater than at solar activity maximum.
