| 摘 要： | 为方便气象业务人员多角度观察雷达回波细节和空间分布情况,本文提出并实现了一个跨平台访问的可交互操作的多普勒天气雷达三维可视化分析平台。首先根据雷达基数据特点提出相邻梯形柱体间隔划分四面体的三维可视化算法,基于B/S模式进行三维可视化分析平台整体架构与设计,最终采用HTML的Canvas技术和WebGL技术实现基于Web的雷达回波的二维、三维可视化显示。试验结果表明,多普勒天气雷达三维可视化分析平台具有良好的三维可视化效果和较好交互式可视化体验,为气象工作者提供了一种有效的雷达回波分析工具。

| Abstract: | For the convenience for the meteorological personnel in the multi angle observation of radar echo in details and the spatial distribution, this paper proposes and implements a cross platform interactive 3D visualization analysis platform of Doppler weather radar. This paper proposes a visualization algorithm based on the characteristics of radar based data. Based on the B/S mode, the overall architecture and design of multi dimensional visual analysis platform are realized. The two dimensional and three dimensional visual display of the Web based radar echoes is realized by using HTML Canvas technology and WebGL technology. The experimental results show that the Doppler weather radar 3D visualization analysis platform performs well in 3D visualization and interactive visual experiences and provides an effective visual analysis tool for meteorologists. |
