Abstract |
Energy dissipation rate in geostrophic turbulence is theoretically estimated, based on the assumption that the energy dissipated in this system is equal to the energy transported to the large wavenumb...er region. In the theory of dynamic scaling laws for the geostrophic turbulence developed by Watanabe et al.(1998), the energy dissipation rate was left unknown and empirically determined;the estimation in this study complements their theory. Through this estimation, the means to determine the appropriate artificial coefficient of the hyperviscosity used in the numerical simulation is also determined. The numerical calculation using this determined value successfully derived the energy spectrum which follows the theoretically expected scaling laws.show more
