<p>A process and apparatus for the day-or-night monitoring of weather phenomena by means of the analysis of the movements of air masses, wherein the movements are determined by monitoring and receiving the multi-band VLF electromagnetic radiation generated in the atmosphere with directionally selective receivers. The received frequencies are then compared with values which have been correlated with atmospheric events. Means are provided for displaying the predictive results for events occurring up to 500 km away from the VLF receivers - typically updatable within seconds - in at least two stages according to the (near or far) range desired or the type of electrical polarization.</p> |
