摘要
本文根据潮波迭加原理,讨论了杭州湾潮波性质对潮流速度与潮差的相关性影响。在杭州湾南部北仑港等地区,由于日分潮和半日分潮波性质不一致,以及相位差的影响,使得该地区落潮流速与落潮潮差的相关程度较高,涨潮流速与涨潮潮差的相关程度较低。在北部湾口附近,由于日分潮和半日分潮波都是前进波,因此,无论涨潮过程或落潮过程,潮流速度与潮差的相关程度都较高。
This paper, on the basis of the superposed principles of tidal waves, the effects of characters of tidal waves on the correlation between current velocities and tidal ranges in Hangzhou Bay are discussed. It is suggested that the correlation degrees between the tidal current velocities and ranges are higher in ebb tide stages, and they are lower in flood tide stages because of the differences of characters between the diurnal constituents and semi-diurnal constituents of tidal waves and the effects of their phase differences in Beilun Harboar waters in Southern Hangzhou Bay. The correlation degrees between the tidal current velocities and ranges are higher during whether flood or ebb tidal processes since the diurnal and semi-diurnal constituents of tidal waves are both progressive waves near the northern mouth in Hangzhou Bay.
