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
