运用Meso-nhm模拟Helsdon and Farley参数化方案的研究

迄今为止，被提出的几种雷暴云起电机制中，最受认可且被认为最重要的是冰—冰碰撞的非感应( NIC： Non-inductive Ice-ice Collision)起电机制。Reynolds et al.(1957)最先开始了NIC 机制的云室试验，类似的试验均以直径较小(通常小于5 mm)的淞附探头代表霰(将霰、冰雹和冻滴统一视为霰)，测量其与冰晶(将冰晶和雪统一视为冰晶)碰撞过程中电荷的转移情况。大量的试验结果表明，霰或冰晶上的转移电荷的极性和量级取决于很多因素。

Application Research Meso-nhm simulation Helson and Farley parameterization schemes

So far,several have been proposed thunderstorm electrification scheme,the most recognized and are considered the most important ice - ice collision of a non-inductive(NIC:Non-inductive Ice-ice Collision)electrification mechanism.Reynolds et al.(1957)first began to cloud chamber experiment NIC mechanism,similar trials are smaller diameter (typically less than 5 mm) is attached to the probe on behalf of sleet Song (the sleet,hail,sleet and freezing droplets are regarded as the) was measured with ice (the ice and snow are regarded as the transfer case ice crystals) charge during a collision.A large number of experimental results show that the charge transfer sleet or ice on the polarity and magnitude depends on many factors.
