Abstract

Mode water forms a 3D region of seawater mass, which has similar physical characteristics values. Research and observation of mode water have a long history in physical oceanography because analysis of mode water brings the understanding of various natural phenomena. There have been various definitions of mode water, and comparison of mode water regions extracted with such various definitions is an important issue in this field. This paper presents our study on comparative 3D visualization tool for the comparison of mode water regions. We extract pairs of outer boundaries of mode water regions as isosurfaces and calculate dissimilarity values between the pairs. The tool visualizes the multi-dimensional vectors of the dissimilarity values by Parallel Coordinate Plots (PCP) and provides a user interface to specify particular pairs of mode water regions so that we can comparatively visualize the shapes of the regions. This paper introduces our experiment on a comparison of mode water regions between an observation and a simulation datasets using the presented tool.

水模态观测比较三维可视化工具

模态水形成一个三维的海水团块区域，具有相似的物理特征值。模态水的研究和观测在物理海洋学中有着悠久的历史，因为模态水的分析带来了对各种自然现象的认识。模态水的定义多种多样，用各种定义提取的模态水区的比较是该领域的一个重要问题。本文介绍了用于模态水区比较的比较三维可视化工具的研究。我们提取模态水区的外边界对作为等值面，并计算它们之间的不相似值。该工具通过平行坐标图(Parallel Coordinate Plots, PCP)将不同值的多维向量可视化，并提供一个用户界面来指定特定的模式水区对，以便我们可以比较地可视化区域的形状。本文介绍了我们使用该工具在观测数据集和模拟数据集之间进行模态水区比较的实验。
