To capture the variability of the internal wavefield in the ocean, we propose to represent the energy spectrum by five parameters (“Adaptive formula for the 2D spectral energy”, Eq. (4)): the high-frequency and high-wavenumber negative slopes, sω and sm; the finite-point singularity ...
2D1). Correspondingly, both u(s) and m(s) simultaneously decline (Fig. 2D2), and the high primary s causing strong IICE is key for the u(s) and m(s) and corresponding SRPR form. The SRPR related to the irregular PSRR in Fig. 1E1 is also irregular because of the different ...
