A sferic, or radio atmospheric signal, is an electromagnetic impulse that occurs as a result of a lightning strike.
That's an important observation when it comes to using the tools we have available, especially since both airborne weather radar and sferics like a Stormscope or Strikefinder are real-time devices.
By tracking strike rate, sferics give instantaneous information on a storm's maturity level and of all the detectors we've tried, Avidyne's TWX670 has the best overall featureset for the price.
Very Low Frequency (VLF) sferics are electromagnetic impulses with frequencies between 1 kHz and 100 kHz, which are generated by lightning discharges.
The limitations on sferics are severalfold, but the biggest for our purposes is that the distance to a strike is essentially estimated based on the strength of the signal; the weaker the energy, the further away it's assumed to be.
These "sounds of lightning" are known as sferics. Fortunately for those seeking to detect the distance and location of lightening, the character of a sferic varies in a known way with distance and path of propagation.
As always, those images should be considered only for advance planning: We've never recommended using them to navigate actual weather--even when backed up by a sferics device.
To decide if sferics is worth the expense for your mission, you need to understand how datalink differs from sferics and the lighting products you're might be receiving via datalink.
