-IC strokes are negative intercloud or intracloud
strokes. Most IC strokes in a typical storm are of the
positive variety. A higher percentage of -IC strokes
(or flashes, when in flash mode) is usually an
indication of a severe storm.
Counters | Percent changes | CG strokes ±%
Toggle the display of the CG ±% counter. CG strokes
are cloud-to-ground strokes.
This counter shows the percentage change in the CG
stroke rate (or flash rate, when in flash mode)
between 60 seconds ago and now.
A sudden change in the CG stroke rate may indicate
unusual storm activity.
Counters | Percent changes | +CG strokes
±%
Toggle the display of the +CG ±% counter. +CG
strokes are cloud-to-ground stroke with positive
polarity. Positive CG strokes occur with much greater
frequency in severe storms. Very distant storms
detected by your detector are necessarily more
severe, and therefore will seem to consist of mainly
+CG strokes.
A sudden change in the +CG stroke rate (or flash rate,
when in flash mode) may indicate unusual storm
activity.
