摘　　要：为检验新旧配方三七炮弹的增雨效果,选用中国科学院大气物理研究所的三维层状云催化模式对河南省春季的一次层状云过程进行模拟,分析新旧配方催化后云体的动力过程和微物理特征,并与未催化情形进行对比。得出新配方的增雨效果优于旧配方;催化后冰相粒子出现时间提前且含量增加,特别是用新配方催化后云体反应更加激烈。In order to verify the effect of precipitation enhancement with 37 shells of new and previous prescriptions, using 3d-stratiform model of IAP,we simulate a stratiform process occurred in Henan province in spring. By comparing dynamic process and microphysical features in unseeded cloud and seeded cloud with new and previous prescriptions, several conclusions are drawn. First, precipitation enhancement effect with new prescription is better. Second, ice phase particles appear earlier and their amount is larger in seeded cloud, especially in seeded cloud with new prescription.
