中文摘要:
      数值模式越来越多地应用在人工影响天气的业务工作中。文中着眼北京地区人影业务对模式预报的需求,结合地基作业的特点,初步进行了冷云催化数值模式在业务中的应用研究,结果如下:冷云催化数值模拟的初始场数据来自同化了多种观测资料的北京市气象局快速更新和多尺度分析预报系统RMAPS (Rapid-refresh Multi-scale Analysis and Prediction System)的预报结果,模拟区域覆盖北京地区所有的地面作业站点以及华北人影飞机作业区域;AgI冷云催化模块耦合在WRF Morrison双参数微物理方案中,主要考虑了冰核和云、雨滴之间的接触冻结核化以及水汽在人工冰核上的凝华核化过程。涉及的步骤包括运行控制实验、根据算法给出作业站点及作业信息运行预催化模拟和重新输入实际作业信息进行重催化模拟。通过个例的应用和对比测试可以不断优化流程算法,初步为前期地面作业方案的制定提供参考,提升了制定地面作业方案的科技水平。
英文摘要:
      Numerical models are increasingly used in weather modification applications. This paper focuses on the demand for model forecasting results in Beijing weather modification applications, and combines the characteristics of ground seeding to study the application of the cold cloud seeding numerical model. Results are as follows:the initial data of the cold cloud seeding numerical simulation come from the Rapid-refresh Multi-scale Analysis and Prediction System (RMAPS) forecast results which assimilated a variety of observation data. The simulation area covers all ground operations stations in Beijing and the North China shadow aircraft operation area. The AgI cold cloud seeding module is coupled to the WRF Morrison two-moment microphysics scheme, which mainly considers the contact freezing nucleation between ice and clouds and raindrops, and the condensation process of water vapor on artifical-ice nucleus. The running steps include running control experiments, running pre-seeding simulations based on the algorithm to give the stations and seeding information, and re-entering the actual seeding information for resimulation. Through the application of individual cases, the process algorithm is continuously modified and improved, which provides a preliminary reference for the formulation of the previous ground operation plan and greatly improves the scientific and technological level of the ground operation plan.
