atmospheric noise

Atmospheric noise is generated in the atmosphere by lightning

and static discharges, which result in a constant noise. Since many thunderstorms and lightning bolts are constantly discharging globally, the interference potential changes due to field strength fluctuations.

Atmospheric noise is subject to seasonal fluctuations, since in certain regions of the world more lightning strikes the earth at certain times of the year, and less in other months. Atmospheric noise is noticeable in radio transmissions in the HF range.
