Tropical Lightning: Electromagnetic Characterization C.O.P.T. 81 Experiment (Tropical Deep Convection)
Abstract
In 1981, the National Telecommunications Research Center (C.N.E.T.) participated in the characterization of the tropical lightnings in the IVORY COAST. In this communication, we present all the electromagnetic measurements results. Two methods were used during this campaign. A time-domain analysis (already used in temperature country, in ST. Privat d'Allier), characterized the radiated signals by lightning return-strokes and these emitted by intra-cloud discharges, the most numerous ones one tropics). From the results obtained, we can effectively define the two types of discharges. A harmonic analysis was made of the instantaneous spectrum evolution during the different lightning phases. During this COPT campaign, we perfected the measurement method for future campaigns, as TRIP 82 (Thunderstorm Research International Program) the first results of which are presented. The data obtained allow us to understand better the physical lightning discharge process and to define the VHF-UHF environment of electronic equipment.
