Three-dimensional numerical calculations of currents east of Taiwan Island in December 1997

摘要

Based on the wind and hydrographic data obtained from the cruise of China-Japan Cooper ative Research on Subtropical Gyre during December 1997, the Kuroshio east of Taiwan Island and the currents southeast of the Ryukyu-gunto are computed by using three-dimensional diagnostic, semidiag- nostic and prognostic models in the σcoordinate. The computed results show that; (1) The density and velocity fields have been adjusted when time is about 15 d, namely, the solution of semidiagnostic calcu- lation is obtained. The quasi-steady state solution has been reached after 300 d, thus and the results of prognostic calculation got.
