散乱体数据可视化:海洋水团分析的新途径

Visualization for Scattered Volumetric Data: A New Approach to Water Mass Analysis

应用科学计算可视化技术于海洋学研究在中国尚不多见。本文试图将这一技术引入物理海洋学领域。文中详细介绍了应用散乱体数据可视化划分和分析海洋水团的方法，包括适于水团分析的数据建模，可视化水团及温、盐度场总体分布及特征分布的体绘制法和等值面绘制法。最后，给出了这些方法在黄、东海毗邻海区５—６月份水团及温、盐度场分布研究中的实际应用。结论显示了科学计算可视化在海洋学研究中的应用潜力。

This paper addresses introduction of scientific visualization technology into the research on physical oceanography. It presents in detail scattered volumetric data modeling, volume rendering method and isosurface rendering method for visualizing ocean water masses and 3-D distributions of water temperatures and salinities. In the end, a case study shows the potential of applying scientific visualization to water mass analysis as well as other fields of physical oceanography.
