Abstract

This study addresses the possibility of application of the discrete mathematical analysis (DMA) methods to develop algorithms for registration of tsunami occurrences on the basis of routine data of sea level measurements. The algorithms are based on the relationship between the regression derivative and the trend of the record: areas of positive (negative) derivatives correspond to increasing (decreasing) trends. Boundaries between these areas are extremums. The article describes three DMA-algorithms for tsunami registration, and performs a comparative analysis.

在海平面记录中登记海啸到达的 DMA 算法

摘要

本研究探讨了应用离散数学分析 (DMA) 方法开发基于海平面测量常规数据的海啸事件登记算法的可能性。算法基于回归导数与记录趋势之间的关系：正（负）导数区域对应于增加（减少）趋势。这些区域之间的边界是极值。本文描述了用于海啸登记的三种 DMA 算法，并进行了比较分析。
