| 摘要: |
| 海气界面二氧化碳(CO2)气体传输速率(Gas transfer velocity,k)的不确定性是当前全球海洋碳汇估算误差中的重要来源，传统单一依赖风速的经验参数化方案忽略了复杂的物理与生化过程，在极端海况与近岸海区存在显著偏差。本文系统梳理了国际海洋学界对k的研究历程，分析对比了不同计算方案的原理与设定，最终总结出k计算方案对全球海洋碳汇评估的影响。本文表明，由波浪破碎和气泡静水压力驱动的非对称传输机制可能导致全球海洋碳吸收量被低估约15%，同时风的历史效应及滞后现象与表面活性剂产生的抑制作用也深刻影响了海气界面碳交换的时空变化。目前，k的参数化方案正经历从“经验拟合”向“过程解析”的范式转变，研究者开始依托涡动相关等手段直接观测，同时与机器学习技术相结合，引入有效波高、波浪雷诺数(RH)等多维参数以重构计算模型。精准量化多尺度过程协同作用下的k，不仅是完善地球系统碳循环理论的基础，更是未来实施海洋CO2移除(marine Carbon Dioxide Removal,mCDR)技术及建立可靠研究体系的科学前提。 |

| Abstract: |
| The uncertainty in the air-sea CO2 transfer velocity (k) is a major source of error in current global ocean carbon sink estimates.Conventional empirical parameterization schemes relying solely on wind speed overlook complex physical and biogeochemical processes,leading to significant biases under extreme sea states and in nearshore waters.This study systematically reviews the evolution of k research within the international oceanographic community,analyzes and compares the mechanisms and formulations of various calculation schemes,and ultimately summarizes the impacts of k parameterization schemes on global ocean carbon sink assessment.Research indicates that asymmetric transfer mechanisms driven by wave breaking and bubble hydrostatic pressure may lead to an underestimation of global ocean carbon uptake by approximately 15%.Meanwhile,hysteresis effects induced by wind history and the suppressive role of surfactants also profoundly influence the spatiotemporal variability of air-sea carbon exchange.Currently,the parameterization of k is undergoing a paradigm shift from empirical fitting to process-based modeling.Researchers are increasingly relying on direct observation techniques such as eddy covariance,while integrating machine learning to introduce multidimensional parameters-such as significant wave height and wave Reynolds number (RH)-to reconstruct calculation models.This study demonstrates that precisely quantifying the gas transfer velocity under the synergistic effects of multiscale processes is not only fundamental to refining the Earth system's carbon cycle theory but also serves as a scientific prerequisite for the future implementation of marine Carbon Dioxide Removal (mCDR) technologies. |
