A Comparative Study of Prelightning Thunderstorm Electrification with Different Noninductive Charging Mechanisms
非感应起电参数化方案的对比性研究

To provide further insight into the applicability of noninductive charging mechanisms to the modeling of intracloud electrification,three different parameterizations of noninductive charging were introduced into the 3D dynamics-electrification coupled model,and electrical evolution before the first lightning was simulated with hailstorm happened on 10 June 2005 in Changchun.The numerical results show that the main charging process moves upward with the development of cloud,and charges accumulated at the-20 ...
