    摘要

    An empirical mode decomposition (EMD) was applied to 20-year (1992-2012) time series of Maps of Absolute Dynamic Topography (MADT) distributed by the AVISO. The Hilbert-Huang transform (HHT) uses the EMD method to decompose a complicated dataset into a finite number of components, the so-called intrinsic mode functions (IMFs). As a result, low frequency and higher relationships have been found in the vicinity of the Western Drake Passage. Lee (2005) has provided a hypothesis that vortex shedding in the eastern South America might trigger El Niño in the tropical Pacific. It could provide a mechanism to explain that there exists a mechanism to trigger both phenomena simultaneously.
