Etymology: "Keraunic" comes from Greek "keraunos," meaning "thunderbolt" or "lightning," and it appears in English in the sense of relating to thunder and lightning. The prefix "iso-" comes from Greek "isos," meaning "equal," so the compound as a whole points to something like "equal in thunderstorm activity." That is exactly what the term describes: maps drawn with lines (isolines) joining places that record the same number of thunderstorm days or lightning strikes per year, so that each region can be compared against others with the same storm frequency. The rest of the compound is a straightforward pairing of an established Greek-derived adjective with a common scientific prefix. Meteorologists use the word as a technical label for these maps, which is where its meaning is most clearly defined and where it is used most often.
