Figure 1

(a) Domain of the innermost (L3) model. Blue shading indicates the bottom topography. Filled circles denote root-mean-square errors of hourly SSHA during July 2012. (b) SSH difference between the Bungo and Kii Channels calculated from the reanalysis data (FORA-WNP30⁶). SSH of these channels is estimated by averaging values on the coast indicated by the orange lines in (a). (c) SSHA for observations of tide gauge data (blue) and TIDE (red) at Matsuyama. Observed sea level data used in (a,c) are download from the JODC website. This figure was prepared with Matplotlib²⁷ (version 2.2.2) package in Anaconda (version 5.2.0, https://www.anaconda.com/).
