【摘要】 风廓线雷达二维显示系统无法显示三维风场,针对此问题,本文研究了基于WebGL的风廓线雷达风场的三维可视化方法。文中介绍了基于WebGL的三维图形渲染技术的原理和优势,详细阐述了风廓线雷达风场的三维建模和渲染方法,在此方法的基础上,开发了B/S模式的风廓线雷达风场三维可视化系统,并介绍了系统的功能特点和优势。相对于风廓线雷达二维显示系统,三维可视化系统以更直观、逼真的形式展现了风场的空间分布,用户能够以任意视角观察三维风场,便于气象工作者分析风场辐合(辐散)、边界层辐合线,为强对流天气监测预报工作提供一种有效的技术手段。更多还原

【Abstract】 Aiming at this problem that the 2 Ddisplay systems of wind profiler radar cannot display 3 Dwind fields,the 3 Dvisualization method of of wind fields from the wind profiler radar based on WebGL is studied in this paper.The principles and advantages of 3 D graphics rendering based on WebGL are introduced,and the 3 D modeling and rendering method of wind fields from wind profiler radar are described in detail.On the basis of this method,a 3 Dvisualization system for the wind fields from wind profiler radar based on the B/S mode is developed,and the functional characteristics and advantages of the system are introduced.Compared with the 2 Ddisplay system,the 3 Dvisualization system presents the spatial distribution of the wind fields in a more intuitive and realistic form,and users can observe the 3 D wind fields from any angle of view,which is convenient for meteorologists to analyze wind convergence(divergence)and boundary layer convergence lines,and provides an effective technical means for monitoring and forecasting severe convective weather.更多还原
