台湾岛地处亚欧大陆和太平洋交界处,台风、东北季风等所引起的海洋灾害频繁,所以建立完备的海洋水文观测体系显得尤为重要。中国台湾自主建置完成的近海水文观测体系由资料浮标站、观测桩、潮位站、岸边气象站、雷达测波站等多种近海水文观测系统构建组成;同时,为确保观测体系的准确性和规范性,还建立了数据品质管理系统和标准化作业模式。在近海水文观测数据的分析方面,尝试应用新的数学分析方法,如通过EMD(empirical mode decomposition)方法探讨风暴潮水位变化,利用小波转换从雷达观测影像中分析近岸波浪信息,以及发展数据同化技术将观测数据应用于作业化波浪现报、预报模式。此外,近海水文观测体系在社会应用方面有着很大的发展潜质。
Taiwan Island is located at the junction of Asia and Europe and the Pacific Ocean. Typhoon and northeast monsoon have caused frequent marine disasters. Therefore, it is particularly important to establish a complete marine hydrological observation system. The offshore hydrological observation system independently constructed by Taiwan Province of China is composed of a variety of offshore hydrological observation systems including data buoy stations, observation piles, tidal stations, shore weather stations and radar stations. In addition, to ensure the accuracy of the observation system And normative, but also established a data quality management system and standard operating mode. In the analysis of offshore hydrological observation data, new mathematical analysis methods such as empirical mode decomposition (EMD) method, storm wave tide level change, wavelet analysis to analyze the coastal wave information from radar observation images and the development of data assimilation The technique applies the observed data to the present report and forecast mode of operational wave. In addition, the offshore hydrological observation system has great potential in social applications.
