摘要本文概述了一个一维的高度相关的冰仓模型，该模型具有详细的微物理过程，其中冰的碎裂是通过边缘过程产生的。利用该模式模拟了不同云团和云顶温度条件下，二次冰产生过程对云内粒子大小分布的影响。模式模拟的结果揭示了云上升气流通过延长冰粒在云中的停留时间和提供足够大的过冷水滴来增加冰粒浓度的总体效果。结冰速率较低的云比结冰速率较高的云更有效。雾气碎裂机制引发的水流星粒度分布演化表明，大冰粒与过冷水滴之间的相互作用增加了初级冰谱的“第二极大值”。
Abstract This paper outlines a one-dimensional, heightdependent bin model with detailed microphysical processes in which ice splinters are produced by a riming process. The model is then applied to simulate the shift of particle size distribution effected by the secondary ice production process within clouds with different generating cells and cloud top temperatures. The result of model simulations reveals the general effects of cloud updrafts on increasing ice particle concentration by extending the residence time of ice particles in clouds and providing sufficiently large supercooled water droplets. The rimesplintering mechanism is more effective in clouds with lower ice seeding rates than those with higher rates. Evolutions of hydrometeor size distribution triggered by the rime-splintering mechanism indicate that the interaction between large ice particles and supercooled water drops adds a “second maximum” to the primary ice spectra.
