抽象。在一个小块模式框架下，发展了一个混合箱微物理方案，以研究天然气溶胶粒子和不同类型的吸湿催化材料如何影响降水的形成。引入一个新的参数来描述不同的种子粒子的液滴尺寸分布的演变的影响。利用混合箱块模式进行的100多个数值试验结果表明：（a）Ostwald成熟效应对云底附近雨滴谱分布的展宽有很大贡献。这种效应的效率随着上升气流速度的降低而增加。(b)吸湿引晶的效率只有在引晶颗粒的尺寸在粗颗粒尺寸范围内时才是显著的。水溶性背景粗颗粒的存在降低了接种的效率。(c)由于播种的大小分布的有效加宽取决于控制情况下的水滴的大小分布的宽度，但这种关系并不像在冰川播种的情况下那么简单。
Abstract. A hybrid bin microphysical scheme is developed in a parcel model framework to study how natural aerosol particles and different types of hygroscopic seeding materials affect the precipitation formation. A novel parameter is introduced to describe the impact of different seeding particles on the evolution of the drop size distribution. The results of more than 100 numerical experiments using the hybrid bin parcel model show that: (a) The Ostwald-ripening effect has a substantial contribution to the broadening of the drop size distribution near the cloud base. The efficiency of this effect increases as the updraft velocity decreases. (b) The efficiency of hygroscopic seeding is significant only if the size of the seeding particles is in the coarse particle size range. The presence of the water-soluble background coarse particles reduces the efficiency of the seeding. (c) The efficient broadening of the size distribution due to the seeding depends on the width of the size distribution of water drops in the control cases, but the relation is not as straightforward as in the case of the glaciogenic seeding.
