Numerical Simulation of Main Negative Charge Area Parameters for Upward Negative Cloud-to-ground Lightning

  • 摘要: 在经典偶极性电荷结构下,结合已有的闪电放电参数化方案及中国气象局雷电野外科学试验基地的广州高建筑物雷电观测站(Tall-Object Lightning Observatory in Guangzhou,TOLOG)观测分析结果,不断调整主负电荷区参数进行二维高分辨率闪电模拟试验,讨论自持型上行负地闪与云中闪电之间的相互竞争关系以及有利于自持型上行负地闪始发的云中电荷结构。数值模拟结果表明:自持型上行负地闪始发与电荷结构存在一定关系,在主负电荷区越高的情况下,始发自持型上行负地闪需要的主负区电荷密度与电荷分布范围越大。对于不同类型的闪电始发条件,推测存在自持型上行负地闪始发的主负电荷区高度阈值,当主负电荷区高度高于该值时,随着主负区电荷量的不断累积,会始发起始于云中的闪电而不是自持型上行负地闪,当主负电荷区高度低于该值时,电荷的不断积累会导致自持型上行负地闪始发。
