不同强度和转移速度的飓风导致的海洋碳循环变化尚未得到系统研究。本研究使用理想化的物理-生物地球化学耦合模型和一套模型敏感性分析来更好地量化飓风特征和海洋特性变化之间的关系，包括空气-海洋碳通量和水中二氧化碳分压 (pCO2w) 的变化。我们发现，强（4-5 类）、中速（5-8 m/s）风暴导致从大气到海洋的碳通量最多，并且海气碳通量与飓风特性之间的关系是非线性的。不考虑天气尺度、风暴引起的物理-生物地球化学耦合的气候模型可能会低估区域碳汇。
Changes in marine carbon cycling due to hurricanes with different intensity and translation speeds have not been systematically investigated. This study uses an idealized coupled physical-biogeochemical model and a suite of model sensitivity analyses to better quantify the relationship between hurricane characteristics and marine property changes, including variations in air-sea carbon flux and partial pressure of carbon dioxide in water (pCO2w). We find that strong (category 4–5), mid-speed (5–8 m/s) storms cause the most carbon flux from the atmosphere to the ocean, and that the relationship between air-sea carbon flux and hurricane properties is non-linear. Climate models that do not consider synoptic-scale, storm-induced physical-biogeochemical coupling may underestimate regional carbon sinks.
