The present study describes estimation of charge and electric field based on the precipitation particle distribution measurement in thundercloud. An X band multi parameter (MP-X) radar and a multi LF sensor network (BOLT) as lightning detectors were used. Polarization parameters obtained from MP-X radar were used to perform the precipitation particle distinction. Distinguished particle distribution from the polarization parameters including graupel gives particle size distribution, and electric charge amount in the collision of graupel and ice crystals. By solving the Poisson equation with charge amount obtained, the electric potential and the electric field have been calculated.
In fact, the present study shows possibility to predict lightning by using MP-X radar through calculating charge and electric field in real time.
