新一代天气雷达常用产品在我国人工影响天气工作中的应用

Application of CINRAD Weather Radar Common Products on Weather Modification in China

随着新一代天气雷达的组网建设,常用雷达产品逐渐在人工影响天气(以下简称"人影")工作中发挥了重要作用。如利用反射率因子产品分析降水系统的移向、移速、强度以及降水性质等特征为人影作业指挥提供参考;利用径向速度产品选择人影作业的最佳时机和部位;利用垂直积分液态水含量产品识别冰雹云并指导防雹作业;综合应用多种雷达产品建立人影作业判别指标和指挥系统并进行作业效果的检验等。但是,诸多雷达产品在人影中的应用上也存在一定的差距和不足。最后,指出现有天气雷达观测网在人影中应用的局限性,并提出毫米波测云雷达、双偏振雷达以及TITAN系统等在人影工作中的应用前景和雷达观测网未来建设的发展方向。

With the network construction of CINRAD weather radar, common radar products gradually have played an important role in weather modification work. For example, analyzing the direction and speed of movement, strength and type of precipitation can provide a reference for operation command. The velocity products can assist in choosing the best operational opportunity and position. The VIL products can identify hail cloud and guide the hail suppression. By integrated application of a variety of radar products on weather modification, command sys- tems and operation parameters can be created and the effective test also can be made. However, there are some gaps and deficiencies in the application of so many products. Finally, some limitations of existing radar observation network are pointed out, but millimeter-wave cloud radar, the dual-polarization radar and the TITAN system can get more potential application. The future development direction of radar observation network is also discussed.
