摘要

摘要潮汐测量站需要对海平面加速度进行检测和量化,以评估人为对气候变化的贡献。尽管如此,均匀或非均匀海平面加速/减速特别难以辨别,部分原因是它们的量级较小,部分原因是低频海平面变化是混杂因素。此外,观测到的海平面变化中的噪声偏移也加剧了估计海平面加速度的可靠性。本研究探讨了海平面加速度的均匀性,这是使用累积和图在最小二乘解的残差中未建模的。本文以美国基韦斯特潮汐测量站的记录为例进行了研究。不考虑加速度参数的严格运动学模型解的残差累积和图显示了该站自1913年以来所经历的清晰而均匀的特征。

Sea level acceleration under the magnifier
Abstract Detection and quantification of sea level accelerations at tide gauge stations are needed for assessing anthropogenic contributions to the climate change. Nonetheless, uniform or non-uniform sea level accelerations/decelerations are particularly di˚cult to discern partly because of their small magnitudes and partly because of the low frequency sea level variations as confounders. Moreover, noisy excursions in the observed sea level variations also exacerbate reliability of estimated sea level accelerations. This study explores the uniformity of a sea level acceleration graphically that is left unmodeled in the residuals of a least squares solution using cumulative sum charts. Key West, USA tide gauge station’s record is studied for a demonstration. The cumulative sum charts of the residuals of a rigorous kinematic model solution without the acceleration parameter revealed its crisp and uniform signature experienced at this station since 1913.
