摘要
采用三维可视化技术,将三维面重建算法和体重建算法引入气象雷达回波图像的分析中,同时与中国气象科学研究院国家灾害天气重点实验室开发的新一代3D组网拼图产品相结合,对2007年9号台风"圣帕"进行了三维显示。结果表明:对于单部雷达体扫产品,三维组网拼图产品能全面地掌握更大范围内雷达回波的演变过程;相对于单一的二维平面的分析显示,三维可视化技术在构建回波的空间分布状况,尤其是回波的空间结构上有更大的优势,三维可视化技术结合雷达三维组网拼图产品为雷达回波的分析提供了一种更为全面的方式。
By means of 3D visualization technology, the 3D surface reconstruction algorithm and the 3D body reconstruction algorithm are introduced into the analysis of weather radar echo images, and in combination with the weather radar 3D networking mosaic products developed by the State Key Laboratory of Severe Weather, Chinese Academy of Meteorological Science, the 3D display of the typhoon ＂Sepat＂ is realized. The results indicate that compared with single radar products, the 3D mosaic products have wider coverage in time and space; compared with 2D display, 3D Visualization has greater advantages in analyzing the spatial distribution of radar echoes, especially in analyzing the structure of radar echoes. The 3D visualization technology combined with 3D mosaic products provides a more comprehensive way for radar echo analysis.
