Description:
The use of lightning (SFERICS) detection has long been dreamed of as a low cost supplement to radar for thunderstorm detection and tracking. Kohl and Miller (1963), Taylor (1973), Graff and O'Malley (1975) have shown a connection between surface severe weather and stories responses. Kohl and Miller showed the relation between rapid sferics increases and the onset of severe weather. Taylor showed how sferics burst rates at 3 MHz increasing at an exponential rate signified the onset of a tornado. Graff and O'Malley tied. Together the periodicity of sferics increases and decreases to the periodicity of severe weather events.

A simple sferics device can he constructed using an A.M. radio and a strip chart recorder. The primary use of this type of sferics unit would be to alert the radar operator to developing convection. Weak electrification begins during the early transition phase from tower cumulus (TCU) to cumulonimbus (CB) (Kohl, 1962). An increase in sferics during a period of no echoes on the PPI could alert the radar operator to look for developing thunderstorms above the freezing level.
