Improved form of wind wave frequency spectrum
Wen Shengchang(S. C. Wen), Zhang Dacuo, Guo Peifang, Wang Wei, Chen Bohai, Tai Weitao
1989, (4): 467-483.
Abstract:
The lower frequency part of the theoretical wind wave spectrum proposed by the authors (Wen et al., 1988a, b, c) has been improved and the form of spectrum is appreciably simplified.In addition to the field data collected in the Bohai Sea region and ...
A combined numerical tidal model for the Hangzhou Bay and Qiantang River
Cao Deming, Fang Guohong
1989, (4): 485-496.
Abstract:
In order to avoid prescribing open boundary condition on the upstream side of the Hangzhou Bay, in numerical simulation of the tides and residual currents of the Bay, a 1-D model for the Qiantang River is connected to the 2-D model for the Hangzhou B...
Basic characteristics and forming mechanism of the sharp thermocline in the Bohai Sea, Huanghai Sea and northern East China Sea
Zhao Baoren
1989, (4): 497-510.
Abstract:
On the basis of the fact that the sharp thermocHne in the Bohai Sea and the northern Huanghai Sea is often distributed in the deep valley areas, it has been long thought that the reason of the formation of the sharp thermocHne is that the cold water ...
Numerical modelling of the sea level under the actions of the tide and strong wind in the Bohai Sea
Zhang Yanting, Wang Yijiao
1989, (4): 511-520.
Abstract:
In this paper, the numerical modelling of the tidal level and current in the Bohai Sea was carried out with ADI method, by taking the sum of four main tidal components M2, S2K2, O1 as the open boundary condition.The calculated values were consistent ...
The low frequency oscillations of the sea surface temperature in the Equatorial Eastern Pacific and El Nino formation
Zhou Faxiu, Yu Shenyu
1989, (4): 521-533.
Abstract:
In this paper the variations of the sea surface temperature anomalies (SSTA) in the Equatorial Eastern Pacific are analysed.The results show that there are two peaks in the spectrum.One is the low frequency oscillation with a period of 3-5 years, and...
Numerical analysis of the sea (lake) breeze dynamics and initialization of the model
Wu Zengmao
1989, (4): 535-547.
Abstract:
In this paper, analysed are the effects of synoptic wind, earth-rotation inertia and land surface roughness on sea (lake) breeze process, on the basis of the calculated results of a 2-D primitive equation model with turbulent energy closure.The resul...
Preliminary research on dissolved oxygen maximum of seawater in low latitude of China
Lin Hongying, Han Wuying
1989, (4): 549-558.
Abstract:
During the multi-disciplinary investigations on the waters of Nansa Islands for three cruises respectively in 1985.1986.1987.it is found that the dissolved oxygen maximum (DOmax) in its vertical distribution usually exists between 20m and 75m deep.Th...
Geological evolution of the Dongsha Uplift and its surrounding depressions in the South China Sea
Li Desheng, Jiang Renqi
1989, (4): 559-564.
Abstract:
The tectonic types of the Zhujiang (Pearl) River Mouth Basin in the South China Sea are epicontinental rift-depression basins.Prior to Early Cretaceous time, the Dongsha Uplift arid its surrounding depressions had been combined with the Eurasia Plate...
Inline forces on vertical pile in irregular waves
Yu Yuxiu, Zhang Ningchuan
1989, (4): 565-576.
Abstract:
The total inline wave forces, the irregular wave forces in particular, on an isolated pile are investigated by experiment.The relationships between force coefficients Cd and CM including in Morison's Eq., and KC number or Reynolds number Re, and the ...
Wave-current force on horizontal cylinder
Li Yucheng, Xu Meikun
1989, (4): 577-586.
Abstract:
For the calculation of wave-current force on horizontal cylinder a modified Morison's equation is used.A redefined Keulegan-Carpenter number KC2 is determined for the horizontal cylinder in wave-current co-existing field.The force coefficients are we...
The relationship between tidal current field and sediment transport in the Huanghai Sea and the Bohai Sea
Dong Lixian, Su jilan, Wang Kangshan
1989, (4): 587-600.
Abstract:
Based on a two-dimensional numerical M2 tidal model of the Huanghai and Bohai Seas, sediment transport of particles with different sizes in the computational area is given.It is concluded that tidal currents play an important role in sediment transpo...
Sources and transport of particulate organic carbon in the Amazon River and its estuary
Cai Deling, F. C. Tan, J. M. Edmond
1989, (4): 601-601.
Abstract:
Preliminary report on the Tunicata in Kuroshio region, southeast of Japan
Lin Hongbai
1989, (4): 601-603.
Abstract:
Trace metal concentration in marine organisms of Huanghe River estuary and adjacent sea region
Liu Mingxing, Zhang Shoulin, Li Guaji, Bao Wanyou, Gu Hongkan
1989, (4): 603-604.
Abstract:
Distribution of chlorophyll a and estimation of primary productivity in the eastern waters of Balingtang Channel in summer

Abstract:
Gill surface architecture of mullet, Mugil soiuy (Basilewsky): A scanning electron microscope study
Wang Liangchen, Guo Shuhua
1989, (4): 606-609.
