METHOD AND DEVICE TO MONITOR THUNDERSTORM ACTIVITY ON EARTH SURFACE IN REAL TIME MODE Russian patent published in 2012 - IPC G01W1/16 

FIELD: measurement equipment.

SUBSTANCE: method includes registration of signals of an extremely low frequency electromagnetic field generated by spark electric discharges and induced in a resonator Earth-ionosphere. Signals are exposed to spectral analysis based on models of extremely low frequency field resonances spreading in the cavity of Earth-ionosphere. As a result of spectral analysis, characteristics are identified, which depend on distance and intensity of spark electric discharges, which are then compared to parameters of the model data base. These models selected as best approximation make it possible to restore location and intensity of spark electric discharges. A device making it possible to restore location and intensity of spark electric discharges is equipped with two inductive magnetic antennas (A_x, A_y), perpendicular one to the other and arranged along directions of north-south and east-west on the earth surface or closely to the surface under the earth. Antennas (A_x, A_y) are connected by shielded wires with a unit that registers signals of observation. The unit comprises two identical tracks of a signal, an amplifier (G_x and G_y), a filter (BPF_X, BPF_y), analogue to digital converters (A/C_x, A/C_y), and also a control module (uP). Signals are sent to an electronic control module of a PC, programmed to perform logics of spectral analysis of extremely low frequency signals and detection of characteristics that depend on the distance to the source and its intensity.

EFFECT: development of a method and a device for global monitoring of thunderstorm activity on the entire Earth surface.
