Comparison of Two Parameterization Schemes for Noninductive Mechanism before the First Discharge in a Simulated Single Cell Storm
雷暴云首次放电前两种非感应起电参数化方案的比较

A three-dimensional dynamic-electrification coupled model is used to investigate noninductive electrification before the first discharge in a single cell of thunderstorm.Two laboratory-based parameterizations of noninductive graupel-ice charge separation,S91 and SP98,are compared.The evolution characteristics of noninductive charge separation regions,polarity,magnitude,structure and their relationships with effective liquid water content,environment temperature,hydrometeor distribution,and convection are an...
