Trusenkova, D. Kaplunenko] Variability of sea level in the Sea of Japan is studied using multivariate analysis of weekly altimetry fields spanning from October 1992 through October 2009. Interacting (non-orthogonal) modes of variability are revealed on seasonal time scale, representing synchronous oscillations in the entire Sea and meridional sea level gradient, respectively. The highest sea level and sharpest gradient occur in October and the strongest opposite phase occurs in March. Intra-seasonal and quasi-biennial synchronous oscillations also occur. The fluctuations of the level gradients are not statistically significant on these time scales. The 180-degree-out-of-phase oscillations occur in the western and eastern parts of the Sea on semiannual, annual, quasi-biennial, and longer interannual time scales, manifesting substantial changes in the regional circulation patterns. No secular trends related to the revealed modes were detected. Pleiades Publishing, Ltd., 2013 Trusenkova O.
