Description:

This work evaluates how clouds evolve to thunderstorms in terms of microphysical characteristics to produce the ﬁrst intracloud (IC) and cloud-to-ground (CG) lightning ﬂashes. Observations of 46 compact isolated thunderstorms during the 2011/2012 spring-summer in Southeast Brazil with an X-band polarimetric radar and two- and three-dimensional Lightning Location Systems demonstrated keyparameters in a cloud ’s vertical structure that produce the initial electri ﬁcation and lightning activity. The majority (98%) of the ﬁrst CG ﬂashes were preceded (by approximately 6 min) by intracloud (IC) lightning. The most important aspect of the observations going into this paper, which came originally from the visualexamination of a large number of thunderstorms, is that an initial positive differential re ﬂectivity ( Z DR)
