摘      要：A frequency-specified empirical orthogonal function(FSEOF)analysis is proposed in this *** aim of FSEOF is to specify a prescribed-band of frequency in leading principal components with less information losing at the ends of the data,thus well characterizing the signals of *** FSEOF can well capture prescribed variability in leading modes,and has intrinsic merits in resolving frequency-related modes,especially those associated with low frequency *** application of the FSEOF to the tropical and northern Pacific sea surface temperature shows that this new method can successfully separate Pacific decadal oscillation(PDO)mode from the El Nino-Southern oscillation mode,and clearly detect all regime shifts of PDO in the past centurv.
