我们使用高分辨率气候模型，根据 21 世纪温室气体排放的两种情景预测了未来海平面及其变化。在两种情况下，由于空间影响导致的全球平均海平面上升分别为 23 和 30 厘米。全球和局部海平面变化的高分辨率模型和同一模型的中分辨率版本的结果非常吻合。然而，高分辨率模型代表了全球变暖下更详细的海洋结构变化。这些变化不仅影响海平面上升的空间分布，还影响与海洋涡流相关的局部海平面变率的变化。增强的涡流活动是造成极端海平面事件的原因。
Using a high‐resolution climate model, we projected future sea level and its variability based on two scenarios for 21st century greenhouse gas emission. The globally averaged sea level rise attributable to the steric contribution was 23 and 30 cm for the two scenarios. The results of the high‐resolution model and a medium‐resolution version of the same model for global and local sea level change agreed well. However, the high‐resolution model represented more detailed ocean structure changes under global warming. The changes affected not only the spatial distribution of sea level rise, but also the changes in local sea level variability associated with ocean eddies. The enhanced eddy activity was responsible for extreme sea level events.
