| 摘 要： | 利用中尺度非静力WRF模式对一次人工消雨过程进行了数值模拟试验。试验结果及实况资料分析表明,在大片的降水云系中对局部的降水云进行过量AgI播撒,由于潜热释放增温使得降水云内的对流加强,促使大量小冰晶在高空向四周流散,云体消散,地面降水量减弱。由此可见,选择合适的作业高度、作业部位是人工消雨取得最佳效果的必要条件。 |
| 关 键 词： | 人工消雨 过量AgI播撒 非静力WRF模式 数值模拟 |

| Abstract: | The mesoscale non-hydrostatic WRF model is used to perform a numerical simulation of the artificial rain dispersal.The results show that excessive seeding of AgI into the cloud of a large precipitation system may enhance the convection due to rising temperature caused by latent heat release,and makes a large amount of small ice crystals scattering in the upper troposphere.Thus the cloud dissipates and the precipitation on the ground decreases.Therefore,it is necessary to perform the seeding at an appropriate height and in an appropriate place of the cloud for effective artificial rain dispersal. |
| Keywords: | artificial rain dispersal excessive seeding of AgI non-hydrostatic WRF model numerical simulation |
