Lightning Activity Observed in Upper and Lower Portions of Storms and Its Relationship to Storm Structure from VHF (Very High Frequency) Mapping and Doppler Radar,

Abstract

Space-time mapping of VHF sources reveals lightning processes for cloud-to-ground (CG) and for large intracloud (IC) flashes are confined to an altitude below about 10 km and closely associated with the central high reflectivity region of a storm. Another class of IC flashes has been identified that produces a splattering of small sources within the main electrically active volume of a storm and also within a large divergent wind canopy at the top of a storm. There is no apparent temporal association between the small high altitude IC flashes occurring almost continuously and the large IC and CG flashes sporadically occurring in the lower portions of storms.
