Radio atmospheric a distance where luminosity is visible and thunder can be heard (typically about 10 km), these electromagnetic impulses are the only sources of direct information about thunderstorm activity on the ground. Transients electric currents during return strokes (R strokes) or intracloud strokes (K strokes) are the main sources for the generation of impulse-type electromagnetic radiation known as sferics (sometimes called atmospherics). While this impulsive radiation dominates at frequencies less than about 100 kHz, (loosely called long waves), a continuous noise component becomes increasingly important at higher frequencies. The longwave electromagnetic propagation of sferics takes place within the Earth-ionosphere waveguide between
Waves Radio In addition to these, a weekly news magazine programme, Making Waves, is broadcast on Sunday evenings from 6.00pm - 7.00pm. The Sportsdesk, a daily round up of sports news, is broadcast at 5.20pm on weekdays. On Saturday afternoons scores and results are updated from 2-6pm on the Sportsmix. 1. History Waves Radio Waves Radio is a local radio station based in Peterhead, North East Scotland. The station is on air 24 hours a day with live shows from 6am till 10pm (apart from "a wave of hits" from 6pm-7pm on weekdays which is automated). Waves Radio was born in 1990
