论文摘要
为了在沿海淹没研究中启用灵活的模型耦合,开发了一个基于ESMF/NUOPC技术的耦合框架,在一个通用建模框架下,称为NOAA环境建模系统(NEMS)。该框架本质上是围绕大气,波浪和风暴潮模型的软件包装器,使其组件可以无缝通信并在大规模平行的环境中有效地运行。我们实施了耦合应用程序,包括ADCIRC和非结构化WaveWatchIII Caps以及NUOPC符合的帽子,以阅读飓风天气研究和预测模型(HWRF)生成的强迫场。我们验证了2008年IKE飓风ike的实验室测试的耦合申请,并在覆盖整个美国大西洋海岸的高分辨率网上验证了。我们展示了表面波与总水位之间的非线性相互作用如何导致淹没和波动侵入飓风登陆区域内及其周围的土地的显着增强和进展。我们还介绍了如何根据登陆区域的风暴轨迹和地理特性在各个时间和位置发生最大波浪设置和最大浪涌区域。
To enable flexible model coupling in coastal inundation studies, a coupling framework based on ESMF/NUOPC technology under a common modeling framework called the NOAA Environmental Modeling System (NEMS) was developed. The framework is essentially a software wrapper around atmospheric, wave and storm surge models that enables its components communicate seamlessly, and efficiently run in massively parallel environments. We implemented the coupled application including ADCIRC and unstructured WWAVEWATCHIII caps as well as NUOPC compliant caps to read Hurricane Weather Research and Forecasting Model (HWRF) generated forcing fields. We validated the coupled application for a laboratory test and a full scale inundation case of the Hurricane Ike, 2008, on a high resolution mesh covering the whole US Atlantic coast. We showed that how nonlinear interaction between surface waves and total water level results in significant enhancements and progression of the inundation and wave action into land in and around the hurricane landfall region. We also presented that how the maximum wave setup and maximum surge regions may happen at the various time and locations depending on the storm track and geographical properties of the landfall area.
