Electric Field Remote Sensing


Thunderstorm electric fields are produced by charge separation on water and ice particles in the updrafts in an active storm. The resulting charge structure is position- and time-dependent as updrafts and downdrafts rearrange charges, charging processes generate further charge separation, and lightning discharges neutralize portions of the storm. Unfortunately, little is known beyond this coarse picture. Additional measurements of the electric field would therefore be very useful.
