摘要：

海啸数值预报技术在海啸预警、防灾减灾工作及海啸物理机制研究工作中都具有举足轻重的作用,特别是在海啸预警及海啸防灾减灾工作中扮演着重要的角色。根据海啸产生及海啸波传播的特征,分别总结了海啸源产生数值模型、海啸传播和淹没模型的研究现状,重点介绍了当前主流地震海啸数值预报模型数值预报技术的发展、预警系统建设及应用现状。旨在为下一步高精度海啸数值预报模型的研究提供指导、为实时海啸预警系统研发提供理论参考。

Numerical forecasting technology play an essential part in tsunami early warning,disaster prevention and reduction(DPR) and tsunami physical mechanism study.It has fundamental significance for tsunami early warning and DPR.Based on the tsunami generation and tsunami wave propagation characteristics,the tsunami source models,tsunami propagation and inudation models are reviewed in this paper.Some important numerical tsunami models which are now in widespread use among tsunami research community were introduced about their implementation methods and application situations.All of the above was summarized in order to provide theoretical reference and guidance for the further research of numerical model and real-time tsunami early warn-ing system.
