Use of dual-polarization radar to map three-dimensional electric 
fields in clouds.

Abstract:

We propose to demonstrate the ability to map electric fields in 
clouds not producing lightning by using dual polarization radar, a 
technique we demonstrated in 1991 at Kennedy Space Center. This 
technique utilizes behavior of the large ice-crystal population in 
a thunderstorm as an indicator of electric fields: ice crystals 
become aligned with the electric field when the field is 
sufficiently strong. Dual-polarization radar can detect the degree 
and direction of alignment.

We will develop an economical strategy for adding an 
electrification hazard detection modification to existing surface-
based and airborne weather radars. The ability of existing radars 
to evaluate storm lightning potential would offer a significant 
enhancement in margin of safety to aircraft operations, missile 
launches, explosives handling, and recreational activities. 
Providing airline pilots with the capability to accurately predict 
the development of regions of intense electrical and convective 
activity will further improve safety and comfort for the traveling 
public.
