- 摘要:
- 在气象领域,天气雷达是观测降水过程的主要工具。随着雷达技术的快速发展,中国新一代多普勒天气雷达开始逐渐升级改造为双线偏振雷达,提供更多的雷达偏振参量,从而更充分地分析天气过程的特征,并不断提高对暴雨、龙卷和冰雹等强对流天气过程的观测和预报能力。为了适应雷达发展过渡期的需求,方便用户使用和查看不同雷达产品,设计了基于Qt的多波段多型号雷达数据处理软件系统。最终实现反射率因子、径向速度、速度谱宽、差分反射率因子、相关系数等基本数据产品和回波顶高、组合反射率因子、垂直积分液态水等衍生产品的生成和预览功能。通过对产品效果进行验证,系统基本能满足使用需求。
- Abstract:
- In the field of meteorology,weather radar is the main tool for observing precipitation processes.With the rapid development of radar technology,the new generation Doppler weather radar in China has gradually upgraded to dual-linear polarization radar.It provides more radar polarization parameters,thus being able to more fully analyze the characteristics of weather processes and continuously improve the observation and forecast capabilities of severe convective weather processes such as heavy rain,tornado andhail.In order to meet the needs of the transition period of radar development and make it convenient for users to use and view different radar products,this paper designs a multi-band and multi-model radar data processing software system based on Qt. Finally,the basic data products such as reflectivity factor,radial velocity,velocity spectrum width,differential reflectivity factor,correlation coefficient and other derivative products such as echo tops,combined reflectivity factor and vertically integrated liquid water are generated and previewed.Through the verification of the product effect,the system can basically meet the use requirements.
