使用一个耦合的大气-海洋模式来研究未来海洋变暖对飓风路径和强度以及相关的沿海风暴潮和淹没的影响,包括水面和水面以下。飓风马修是萨菲尔-辛普森5级强飓风,于2016年9月登陆美国南卡罗来纳州海岸,并被用作我们的研究案例。未来海洋变暖是根据政府间气候变化专门委员会(IPCC) RCP 2.6和RCP 8.5情景计算的。利用验证后的模型模拟了未来气候海洋变暖情景下飓风马修的路径、强度、风暴潮和淹没的变化。结果表明,未来海洋变暖可能使飓风强度增强,进而大大增加随后的沿海风暴潮和淹没。例如,在RCP 8.5情景下,马修的最大风速将增加18节(12.97%),最低海平面压力将加深26 hPa(2.78%),沿海被淹没面积将比现在增加70.20%。此外,沿海风暴潮和洪水的增加可能会导致下游对上游水系的阻塞,从而加剧上游横向洪水,因为河流进入蓄水模式;但这种潜力超出了本研究的范围。
A coupled atmosphere–ocean model was used to study the impact of future ocean warming, both at and below the water surface, on hurricane track and intensity and the associated coastal storm surge and inundation. A strong Saffir–Simpson Category-5 hurricane, Hurricane Matthew made landfall on the South Carolina (SC) coast of the United States (US) in September 2016 and was used as our study case. Future ocean warming was calculated based on the Inter-Governmental Panel on Climate Change (IPCC) RCP 2.6 and RCP 8.5 scenarios. Validated setup of the model was used to simulate the changes in track, intensity, storm surge, and inundation of Hurricane Matthew under future climate ocean warming scenarios. Results showed that the future ocean warming could make the hurricanes stronger in intensity, which, in turn, will greatly increase subsequent coastal storm surge and inundation. For example, under the RCP 8.5 scenario, Matthew’s maximum wind speed would increase by 18 knots (12.97%), its minimum sea-level pressure would deepen by 26 hPa (2.78%), and the coastal area inundated would increase by 70.20% from that of the present day. Moreover, the increases in coastal surge and inundation could likely lead to a downstream blocking of upstream water systems, thereby exacerbating upstream lateral flooding as the rivers go into storage modes; but that potential is beyond the scope of this study.
