Abstract

Some data of currents of lightning events measured in Morro do Cachimbo Station during the period 2008-2012 are presented, comprising 9 downward negative first strokes (4 of them pertaining to multiple-stroke flashes), 8 unconnected upward leaders developed in response to downward negative leaders approaching the ground and 5 negative upward lightning. The current waves of all negative upward lightning are presented along with an example of representative waves for first stroke and unconnected upward leader currents. Parameters of such currents are summarized.
