Global Variation in Atmospheric Electric Field on the Sea Surface
Year: 1970
Type: article
Abstract: An analysis of the global nature of atmospheric electric field on the ocean is presented on the basis of measurement on the research vessel, Hakuho-Maru. The daily averages of electric field ranging 50 to 140 v/m give a latitude dependence, that they are higher as much as 25％ in high latitude than in low latitude, in spite of widely dispersed values. On the other hand, the diurnal course of electric field displays more or less a typical variation in phase with the thunderstorm activity integrated over the entire globe. Some changes in the hours that give the maximum field in daily courses, when they are averaged for every 10 degrees latitude section, seem to suggest the regional effect due to the distance from thunderstorm areas acting as the generator of global atmospheric electrical circuit.
