摘　　要：详细介绍了国家海洋环境预报中心发展的海上失事目标搜救应急预报系统。该系统基于四阶精度的拉格朗日漂移路径模型,以预报中心发展的高分辨率风场和流场数值预报的结果作为环境动力强迫条件,预报落水人员或失事船舶(渔船)的漂移轨迹,预报结果可基于Googleearth平台显示。该系统的应用有助于提高海上搜救行动的及时性和有效性,减少失事人员死亡率和失事船舶失踪率,减少经济损失,具有很高的实用价值。The marinetime search and rescue emergency forecast system, developed by National Marine Envi- ronmental Forecasting Center （NMEFC）, is introduced in this article. Based on fourth-order Runge-Kutta lagrang- ian drift method and driven by high-resolution sea surface wind and numerical current forecast system which is al- so developed by NMEFC, the system can provide drift trace of wrecks or drowning people. The forecast product can be displayed on the Google earth platform. This forecast system can improve the timeliness and effectiveness of maritime search and rescue and has proved its value in mitigating personnel casualty and economic loss.
