Analysis of the network mechanism for sea surface temperatures around the Korean Peninsula

The complex network in meteorological phenomena can be investigated from the sea surface temperature (SST) in the East, the Yellow, and the South Seas. For this study, we treat the Hurst exponents that are calculated from the rescaled range analysis (RRA) in spring, summer, autumn, and winter. We estimate and analyze the hub cells of the SST from the network theory for three different Hurst exponents of 0.001, 0.003, and 0.005. Particularly, we find in the East Sea that the same hub cell exists between three ranges of the Hurst exponent for winter.
