abstract = "Studies of upward flashes from tall structures around the world
have been reported since 1939. The characteristics of the
triggering mechanism and of the upward flashes are of increasing
interest to wind power turbines, telecommunication toware and
power distribution companies. Observations of upward flashes in
Brazil are recent. Since 2012, upward events were observed in all
different seasons of year. They initiate on several towers in Sao
Paulo, a city in southeast Brazil at an average elevation of
around 800 meters above sea level and a flash density of 15
flashes/kmē.year. Some of the towers are located on top of
buildings or hills. In this study, we will present some
characteristics of these upward flashes, based on high speed video
observation: flash duration, presence of subsequence of return
stroke, previous lightning events, initial continuous current
pulses and the presence recoil leader.",
