The convective storm season with associated lightning activity over this region is short hut intense, with a strong peak in cloud-to-ground lightning during July. The maximum area of lightning activity is influenced by local moisture sources and by topography. The diurnal distribution of cloud-to-ground flashes indicates that most of the lightning was linked to thunderstorms initiated by daytime heating. The...
