摘　　要：A review of the state of knowledge and phenomenology on the site of the greatest atmospheric electrical activity in the world,known as the Catatumbo Lightning,located southeast of Lake Maracaibo(Venezuela),is presented.A microphysical model is presented to explain the charging process through electrical displacement within the cells of the cloud,incorporating the role of the self-polarization of ice and methane molecules as pyroelectric aerosol,which accounts for the phenomenology and is consistent with electrification in thunderstorm.It is concluded that the pyroelectric model allows to explain the phenomenology of the rapid discharges of the flashes in the Catatumbo lightning and could be applied in outer planetary lightning.
