Effects of electromagnetic wave propagation over the Caribbean from satellite broadband data

To study electromagnetic signals and search for functional connections with sources of disturbances of natural and anthropogenic origin, digital equivalents of recording observations in the frequency range from 20 Hz to 20 kHz on satellites over the Caribbean are used. Graphs of the dependence of the number of signals per minute on time along the satellite orbit are plotted. Fractionally dispersed whistlers at frequencies below 1 kHz (ELF fdw) ranged from 30 to 100% of the total number of fdw. This estimate coincides with the results of ground-based observations of the ELF atmospherics (“tails”) under different conditions. There was an increased frequency of occurrence of fdw and ELF fdw during the action of typhoons in the Pacific Ocean, especially at the stage of depression, and hurricanes in the Atlantic, in the area located on both sides of the meridian passing through the Brazilian anomaly. These results are confirmed by the work of other researchers.
