The effect of ice nucleation on thunderstorm charge structure

Base on existing two-dimensional convective cloud model, this work adopts a nucleation scheme associated with aerosols to replace the original ice crystals nucleation empirical formula and the two kinds of schemes are used for simulation contrast test with sample, respectively. Simulation results show that: (1) Compared to the original scheme, the charges of new scheme increase and its charge distribution region expands. (2) Charge of the new scheme occurs earlier than the original scheme and there is inverted dipolar charge structure in the new scheme. (3) Two schemes form two different charge structures.
