Abstract : Electrical alignment of precipitation particles was detected in an electrified storm using the co- and cross-polar channels of the radar. The radar receiver chain was upgraded and modern signal processing and display equipment added. The system was taken to Kennedy Space Center for final checkout and data- gathering independently and in conjunction with the CaPE program. Using the cross-polar correlation magnitude and phase displays as a guide, it was possible to accurately predict the outset of electrification and attendant lightning discharges, and to determine when a storm would no longer produce lightning. Several publications documenting the effect are included. A patent on the cross- polar correlation technique is being sought.
