abstract = "The study of lightning is a topic that has gained significant
attention in the scientific community. By monitoring the periods
of higher flash incidence, it is possible to issue alerts with
information about the intensity, duration and severity of the
storm, so that preventive measures can be taken in order to
minimize the impacts of severe weather phenomena. In this context,
the objective of this study was to identify extreme events of
lightning that occurred in the state of S{\~a}o Paulo, in
Southeastern Brazil, during 2011-2013 and analyze the correlation
between intra-cloud and cloud-to-ground lightning in these events.
Lightning data used in this study are from the Brazilian lightning
detection Network - BrasilDAT. Extreme events were selected using
the Method of Percentiles, applied to the data of intra-cloud and
cloud-to-ground lightning in 13 (thirteen) cities spatially
distributed within the state of S{\~a}o Paulo. We considered the
extreme events as those days when the number of both types of
discharges were higher than Percentile 98. As a result, we obtain
31 cases, with total lightning occurrence exceeding 10.000. For
these events, we found a characteristic intra-cloud to
cloud-to-ground ratio that can be used to identify these extreme
events.",
