Meso-nh起电参数化方案研究进展

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。这些影响因素包含碰撞粒子的大小、相对降落末速、云温、液态水含量等,它们都对非感应起电率都有所影响。当在参数化方案中考虑的因素不同时,每次碰撞时所转移电荷的数量和极性均有所差异。

Progress in the electrical parameters of the program from the Meso-nh

A large number of experimental results show that the charge transfer sleet or ice on the polarity and magnitude depends on many factors.These factors contain the size of the colliding particles, relative to the end of the landing speed,temperature and cloud liquid water content,etc.,which are non-inductive power rate has affected right.When the factors considered in the parameterization scheme is not the same each time the collision transfer charge amount and polarity were different.
