Lightnings serve as an important charge transporter between cloud and ground, and emit sferics those
propagate in the ground-ionosphere cavity. The question on how global lightning activity might change in the
future as a result of the global warming has attracted great attention. During the three-year observation of
ISUAL/FORMOSAT-2, besides upper atmospheric transient luminous events more than 60,000 lightnings which
exceeded the trigger threshold were recorded. In this presentation, the distribution, occurrence rate, and
seasonal variation of these lightnings at local time between 22:30 and 23:00 will be reported, and compared with
that of the OTD/LIS experiment (Christian, et al., 2003). Our results may suggest that intensive lightnings are
possible more efficient to generate elves, and the production efficient is assessed in this presentation.
