The atmospheric electric field In a clean sky day the atmosphere is home of a electric field with intensity of 100 V/m, produced of a superficial negative discharge. When a storm is approaching discharges are distributed as shown in picture: the clouds base is strongly negative, so, given its closeness to the ground of 2-3 Km. It is forming an electric field of about 1000 V/m with a potential difference between clouds and ground of 2 – 3 millions Volts. http://www.vlf.it/nrs/nrs.htm TEPA-2015, October 5-9, Byurakan, Armenia
