摘要: This study evaluates the influence of various climate modes on sea level. The altimetry record has excellent spatial coverage but limited length becomes an issue when evaluating low frequency variability in presence a trend. We use along with two ocean models to how relationship between surface height (SSH) Indian and Pacific Oceans four [the Decadal Oscillation (PDO), El Nino–Southern Oscillation, Ocean Dipole Southern Annular Mode] depends time series. For such as PDO, series order 50 years is required separate from Using shorter results aliasing SSH trend variability, which implications for ascertaining role PDO trends. find that regression during period, thought have been responsible large fraction recent western trend, not representative SSH–PDO longer-term record.
