Abstract

Abstract: CEOF and wavelet methods were employed to discuss the relationship between the main modes of upper circulation anomalistic field in the North Pacific during winter and the PDO, NPGO modes. The results show that the first and second CEOF modes of the upper circulation anomalies are the reflection of the PDO and NPGO modes on the circulation field. Firstly, the real time coefficients of the first two modes have obvious decadal periods of about 20 and 13 years, respectively, which are the same as the periods of PDO and NPGO modes. Secondly, the regression fields of the first two time coefficients with the SSTA in the North Pacific are quite similar to the spatial feature of PDO and NPGO modes. The distributions of dynamic anomalies of near-surface temperature obtained by the vertical movement of the first two modes of the upper circulation anomalies are similar to those of PDO and NPGO modes. This means that the vertical movement of oceanic flow is the important reason of formation of PDO and NPGO modes.

Key words: North Pacific, circulation field anomalies, CEOF, PDO, NPGO
