A modeling study has been conducted to simulate the June 13, 2013 U.S. East Coast meteotsunami event as a test of the model forecast concept. A numerical simulation based on the MOST (Method of Splitting Tsunami) model was employed for the meteotsunami propagation forecast, while the weather radar reflection imagery was used to simulate real-time input data for the atmospheric pressure-induced tsunami generation. The model tsunami was generated by a moving pressure field during 2.87 h of forcing, and the resultant tsunami was then simulated for additional 5.68 h of propagation without any forcing for a total of 8.55 h of meteotsunami evolution from generation to coastal impact. Simulated time series were compared with the measurements from sea-level coastal gages and the Deep-ocean Assessment and Reporting for Tsunami (DART) data. The model is able to reproduce in general the recorded sea-level changes in the deep ocean and at the coast in terms of arrival times and amplitudes. The model was able to predict coastal tsunami impacts that occurred from one to two hours after the model data assimilation phase ended. Therefore, this approach shows promise for developing meteotsunami model forecast capability based on measurements and data assimilation in real time, at least for meteotsunamis generated by fast-moving weather systems visible on radar reflection imagery. All the data used in this study are already available in real time, the MOST model is already implemented as a seismically generated tsunami forecast model at the Tsunami Warning Centers (TWCs), which makes transition of potential meteotsunami forecast capability to warning operations straightforward.

进行了建模研究，以模拟2013年6月13日的美国东海岸Meteotsunami事件，以对模型预测概念进行测试。利用基于MOST（海啸分裂方法）模型的数值模拟进行海啸的传播预报，同时使用天气雷达反射图像模拟大气压诱发海啸发生的实时输入数据。模式海啸是在强迫作用2.87小时内由移动压力场产生的，然后模拟了由此产生的海啸，进一步传播了5.68小时，而没有任何强迫作用，导致了从生成到沿海撞击共发生了8.55小时。将模拟的时间序列与海平面沿海测量仪的测量结果以及“深海海啸评估和报告”（DART）数据进行了比较。该模型通常能够再现到达时间和幅度方面在深海和海岸记录的海平面变化。该模型能够预测在模型数据同化阶段结束后一到两个小时内发生的沿海海啸影响。因此，这种方法显示出有望开发基于实时测量和数据同化的气象海啸模型预测能力，至少对于雷达反射影像上可见的快速移动天气系统产生的海啸而言。该研究中使用的所有数据均已实时提供，MOST模型已在海啸预警中心（TWC）上作为地震产生的海啸预报模型实施，这使潜在的气象海啸预报能力向预警行动的过渡变得简单。
