Oceanic model steady state decision manner, the wind stress data of the oceanic model steady state

摘要

PROBLEM TO BE SOLVED: To provide an ocean model steady state determination method, an ocean model steady state determination device and its program for determining objectively attainment of the steady state by displaying a time series change of sea area average kinetic energy.;SOLUTION: The kinetic energy at each point is calculated by a kinetic energy calculation part 3 based on the flow velocity and the density calculated by a marine environment calculation part 2 by using as an input a wind stress generated by a wind stress data generation part 1. A sea area average kinetic energy calculation part 4 calculates the mean value of the kinetic energy in the whole sea area. A baroclinic Rossby wave propagation time calculation part 5 calculates a time until a disturbance generated on the shore on one side of the sea area reaches the shore on the other side. A time series change of the sea area average kinetic energy is displayed on a sea area average kinetic energy display part 6, and a baroclinic Rossby wave propagation time is displayed on a baroclinic Rossby wave propagation time display part 7, to thereby assist determination of attainment of the steady state.;COPYRIGHT: (C)2006,JPO&NCIPI
