abstract = "The Upward Lightning Triggering Study (UPLIGHTS) is a three-year
National Science Foundation-funded field project that is taking
place in Rapid City, South Dakota, from April 2012 to September
2014. Three upward flashes that occurred within a 20-min period
were all triggered by a preceding +CG (cloud-to-ground) flash. In
each case, in-cloud brightening following the +CG propagated
toward the towers prior to upward leader initiation. Supporting
electric-field data suggested that the approaching in-cloud
brightening was horizontally propagating negative-leader
development occurring during the +CG continuing current, and that
the electric-field change created by the approaching negative
leaders caused the initiation of upward positive leaders from the
towers. Although none of the 10 towers had current sensing
instrumentation, it is likely that a large majority of the upward
flashes were upward negative lightning. The research may result in
improved detection of upward lightning by lightning location
systems.",
