在1979年我国首次对西太平洋东部的赤道海区调查研究的基础上,我们对此海区进行了海流的诊断计算。计算表明,定常风场对表面流的影响很大,但随深度增加,它的影响减小了,在75m层或100m层,几乎没有影响。由于定常的偏东风的作用,在上层引起发散的西向流,由此将在赤道附近产生上升流。潜流的最大速度为88—90cm/s,出现在200m水层上。本文对深层流作了简单的讨论。 Based on the first survey of equatorial sea areas in the eastern part of the western Pacific Ocean in 1979, China conducted a diagnostic calculation of ocean currents in this area. The calculation shows that the steady wind field has a great influence on the surface flow, but its influence decreases with the increase of depth, and it has little effect on the 75m or 100m layer. As a result of the steady east-easterly wind, a divergent westward flow is induced at the upper level, and as a result, an upward flow is generated near the equator. The maximum velocity of the underflow is 88-90 cm / s, appearing on the 200 m water layer. This article made a brief discussion of deep flows.
