Record number: 2, Textual support number: 1 CONT
Atmospherics are heard as a quasi-steady background of crackling noise (static) on certain radio frequencies, such as those used to broadcast AM radio signals. Since any acceleration of electric charge leads to emission of electromagnetic radiation, and since the several processes involved in propagation of lightning lead to very large charge accelerations, the lightning channel acts like a huge transmitter, sending out radiation with frequencies of the order of 10 kHz. 7, record 2, English, - atmospherics

Bruit de fond. On constate également que jusqu'aux bandes UHF, les ondes propagent de nombreux parasites et bruits divers qui se superposent aux signaux. Cela commence dans les longues ondes(LW ou AM) sujettes aux parasites atmosphériques(éclairs, etc), cela s’étend aux VHF sensibles aux aurores et aux traînées d’ionisation des météores pour s’atténuer vers 500 MHz environ. Il faut donc monter en fréquence pour s’abstraire de ces problèmes. 4, record 2, French, - parasites%20atmosph%C3%A9riques

Among the natural field EM [electromagnetic] methods are the AFMAG (audio-frequency magnetic field), the AMT (audio-magnetotelluric), and the magnetotelluric methods, which make use of the electromagnetic energy in selected frequency ranges from natural sources such as lightning discharges and ionospheric oscillations. 1, record 4, English, - audio%2Dfrequency%20magnetic%20field

The first "passive transmitter" AEM system, AFMAG was introduced in 1958. This system utilised a natural audiofrequency magnetic field arising from atmospheric discharges as the source of the primary field. 3, record 4, English, - audio%2Dfrequency%20magnetic%20field
