SAN FRANCISCO--Data from a 1996 Colorado experiment is illuminating a new class of lightning flashes thousands of times faster than those previously observed. NCAR scientist Eric Defer is analyzing data on a set of short-duration intracloud flashes that can play out as quickly as 23 millionths of a second, and perhaps even faster than that. (Intracloud flashes average about a quarter of a second in duration. Cloud-to-ground lightning flashes can last more than a second.) He presented his findings this week at the annual meeting of the American Geophysical Union.
