| Abstract | There are multi-spatial-scale ocean dynamic processes in the western boundary current region, so the budget of energy source and sink in the Kuroshio Current area can describe the oceanic energy cycle and transformation more accurately. The slope of the one-dimensional spectral energy density varies between -5/3 and -3 in the wavenumber range of 0.02-0.1 cpkm, indicating an inverse energy cascade in the Kuroshio of Taiwan Island and the East China Sea. According to the steady-state energy evolution, an energy source must be present. The locations of energy sources were identified using the spectral energy transfer calculated by 24 years of Ocean General Circulation Model for the Earth Simulator (OFES) data. At the sea surface, the kinetic energy (KE) sources are mainly within 23.2 degrees-25.6 degrees Nand 28 degrees-29 degrees N at less than 0.02 cpkm and within 23.2 degrees-25 degrees N and 26 degrees-30 degrees N at 0.02-0.1 cpkm. The available potential energy (APE) sources are mainly within 22 degrees-28 degrees N and 28.6 degrees-30 degrees N at less than 0.02 cpkm and within 22.6 degrees-24.6 degrees N, 25.4 degrees-28 degrees N and 29.2 degrees-30 degrees N at 0.02-0.1 cpkm. Beneath the sea surface, the energy sources are mainly above 400 m depth. Wind stress and density differences are primarily responsible for the KE and APE sources, respectively. Once an energy source is formed, to maintain a steady state, energy cascades (mainly inverse cascades by calculating spectral energy flux) will be engendered. By calculating the energy flux at 600 m depth, KE changes from inflow (sink) to outflow (source), and the conversion depth of source and sink is 380 m. However, outflow of the APE behaves as the source. |
