Observations of prolific transient luminous event production above a mesoscale convective system in Argentina during the Sprite2006 Campaign in Brazil

Cummer, Steven (AMER GEOPHYSICAL UNION, 2010)

On the night of 22-23 February 2006, 444 transient luminous events (TLEs), 86% sprites, were observed above a prolific mesoscale convective system (MCS) over Argentina, as part of the third sprite campaign in Brazil. GOES ...
Polarity and energetics of inner core lightning in three intense North Atlantic hurricanes

Cummer, Steven (AMER GEOPHYSICAL UNION, 2010)

We use the World Wide Lightning Location Network (WWLLN), low-frequency magnetic fields measured at Duke University, and storm intensity data (winds and central pressure) to examine the polarity and energetics of lightning ...
