摘要:
本文根据实测海流资料,对大连湾的海流分布特征及其变化规律作了初步探讨。结果表明,大连湾属于非正规半日潮流区,M2分潮流主流向基本与岸线平行,呈往复流运动。湾口三山岛水道附近为一强流区,实测涨潮流可达2.5kn,秋季表层余流流速接近0.8kn。

STUDY OF THE DISTRIBUTION CHARACTERISTICS OF CURRENT IN DALIAN BAY
Abstract:
Studies of the characteristics and the regularities of current show that Dalian bay belongs to non-semidiurnal tial current area. The direction of longer axes of the M2 tidal current is parallel to the coastal line in the rectilinear current movement. The strongest current appears in the channel of the bay mouth with a velocity of 2.5 kn. The velocity of the residual current is about 40 cm/s at sea surface in autumu.
Key words:  M2 tidal current, Rectilinear current movement
