- Twelve years of continuous measurements of atmospheric electrical activity in México`s Tropical Highland O. Troncoso Lozada Biología lightning electrical discharges Atmospheric electricity Atmospheric electric activity measurements have been recorded continuously by a punctual lightning systemat a tropical highland observatory from 1988 onwards, and were analyzed to obtain lightning statisticalconfident results for thunderstorms occurrence on the leeward side of the southern mountain ridge of MéxicosValley. Shown, as examples, are individual profiles of the atmospheric electrical activity, associated withsevere storms. The results make clear that the fastest possible sequence of electrical measurements is requiredto obtain significant and application oriented data in connection with a whole series of thunderstorms takinginto account the mean time variation of the atmospheric electricity measurements at an altitude of 2270 m a.s.l.The seasonal variation indicates that the lightning flash peak currents were found to be larger in summer withless than 10% occurring in the autumn and winter. With rainfall data from a network of 66 stations, weobtained a significant correlation with the lightning frequency. Special attention was undertaken concerningthe question of the atmospheric electrical activity and climate at the Valley of México. 2004 artículo científico 0187-6236 https://www.redalyc.org/articulo.oa?id=56517201 en http://www.redalyc.org/revista.oa?id=565 Atmósfera application/pdf Universidad Nacional Autónoma de México Atmósfera (México) Num.2 Vol.17
