FEASIBILITY OF MEASURING VERTICAL ELECTRIC FIELDS IN CUMULUS CLOUDS USING A HOT-AIR BALLOON AND A HELICOPTER.
Abstract
A hot-air balloon was used but rejected; a helicopter was also used for measuring electric fields in clouds. Dynamic variations of electric field were detected within growing cumulus clouds; these variations are caused by internal advective and convective motions. Because the magnitudes of the field changes are small, a constant redistribution of space charge carried aloft in the updraft is suggested. A recommendation is made that complete electrical evaluation of cumulus clouds be made: from nucleation to cumulo-nimbus development. A high-performance helicopter should be utilized. (Author)
