Dynamical statistic analysis of decadal anomalies Air-sea
Abstract
In this paper, the Complex empirical orthogonal Function (CEOF) and wavelet analysis methods are employed to Stu Dy the decadal variations of the The I and second modes of atmospheric and oceanic circulation in the North Pacific during Winter. The relationships between them and the Pacific decadal Oscillation (PDO) and North Pacific gyre (oscillation) mode AR e also discussed. The correlations between the time coefficients of the the ' the ' two modes and the PDO and NPGO index are high, and The wavelet analysis of the time coefficients show obvious decadal periods of about years, respectively, which a Re the same as the decadal variations of the PDO and NPGO mode. The regression coefficient field of the the ' the ' the ' the ' the ' two time coefficients with the SST anomalies (sstas) is quite similar to the Spatial distribution of the PDO and NPGO mode. The spatial distributions of the two modes of atmospheric circulation anomalies resemble those of the Aleutian Low ( AL) mode and North Pacific Oscillation (NPO)
