1950~2010年PDO对北太平洋地区海平面变化影响的量化与评估
Quantification and evaluation of PDO influence on north Pacific SLR during 1950–2010
摘要
Abstract
In this paper, the influence of different Pacific Decadal Oscillation (PDO) events are investigated and estimated during 1950–2010 in the North Pacific. Simple ocean data assimilation (SODA) sea surface height (SSH) data are used to separate PDO-induced SSH varieties (PDO-SSH) by applying the multiple linear regression method. Results show that the obtained PDO-SSH induced sea level rise and its obscure-effect are closely related to the am-plitude and period of the corresponding PDO signal. Further analysis shows that the influence of PDO events in the North Pacific is not uniform, and an opposite sign is observed in the Eastern and Western Pacific. The long-term PDO signal during 1960 to 1989 has a stronger influence than the altimeter period, and the areas most influenced are the western equatorial Pacific, Aleutian Islands, and coast of North America, where PDO-SSH in these regions accounts for nearly 60% of observed SSH.关键词
