泻湖系统受飓风影响更为严重，而相关的风暴潮建模研究很少关注泻湖系统，对泻湖系统中风暴引起的交换更是了解甚少。为了解决这一差距，我们为马里兰州沿海海湾配置了一个基于三维非结构化网格的模型，这是一个典型的泻湖系统，具有两个独特的入口（海洋城入口 (OCI) 和钦科蒂格入口 (CI)），以研究飓风桑迪如何影响入口动态。应用嵌套模型框架来提供来自大型模型域的必要远程强迫，并维护内部模型域的复杂海岸线和测深。结果表明，在桑迪通过期间，通量模式随着风向的变化和沿海海洋高水位的上升/下降而变化，而不是单一的流动模式。世界标准时间 10 月 29 日 05:00 至 17:00，温和（> 10 m/s）和强（> 15 m/s）北风伴随着沿海海洋高水位上升，促进了 OCI 的平均流入模式和 CI 的平均流出模式。世界标准时间 10 月 30 日 03:00 至 15:00 期间，海湾盛行强西南风 (> 15 m/s)。在强烈的西南风和沿海海洋高水位下降的情况下，通量在 CI 处向陆地输送，在 OCI 处向海洋输送。不同风暴时间尺度的敏感性实验表明，海湾出现净流入模式，并且净交换量随着风暴持续时间的延长而变小。来自桑迪的相对较高的河流流量的残余效应仍然会影响OCI处的盐度，而CI盐度由于CI和河流位置之间的距离较远而不受河流流量的影响。
Lagoon systems are more heavily impacted by hurricanes, whereas the relevant storm surge modeling studies have been paid little attention to lagoon systems and the storm-induced exchange in lagoon systems is even less understood. To address this gap, a three-dimensional unstructured grid-based model was configured for the Maryland Coastal Bays, a typical lagoon system with two unique inlets (Ocean City Inlet (OCI) and Chincoteague Inlet (CI)), to investigate how Hurricane Sandy impacted inlet dynamics. A nesting model framework was applied to provide the necessary remote forcing from a large model domain and maintain the intricate shoreline and bathymetry of an inner model domain. Results indicated that the flux patterns varied in response to the change in wind direction and rising/falling high water levels from the coastal ocean, rather than a single flow pattern during the passage of Sandy. From October 29 05:00 to 17:00 UTC, mild (> 10 m/s) and strong (> 15 m/s) northerly winds accompanied by the rising high water level from the coastal ocean promoted a mean inflow pattern at the OCI and a mean outflow pattern at the CI. Strong southwesterly winds (> 15 m/s) dominated in the bays from October 30 03:00 to 15:00 UTC. Under strong southwesterly winds and falling high water levels from the coastal ocean, flux was transported landward at the CI and seaward at the OCI. Sensitivity experiments on various storm temporal scales showed that a net inflow pattern occurred in the bays, and the net exchange amounts became smaller in response to longer storm durations. Residual effect of relatively high river flow from Sandy could still influence the salinity at the OCI, whereas the CI salinity was not affected by river flow owing to a long distance between the CI and river locations.
