Study on dynamics of shear waves——Ⅰ. Scale analysis and dispersion relation
Zheng Quan'an, Yuan Yeli
1989, (2): 161-170.
Abstract:
Starting from satellite remote sensing data, the dynamical processes of shear waves occurring at the boundary between the western boundary current and the shelf slope water are studied and dynamically analyzed in this study. The average wavelength is...
Study on dynamics of shear waves——Ⅱ Triggering mechanism and amplitude decay
Yuan Yeli, Zheng Quan'an
1989, (2): 171-178.
Abstract:
Starting from vorticity equation, the triggering mechanism and amplitude decay of shear waves in the ocean are discussed in this paper. The theoretical analysis indicates that by the action of stripped external force (for examples, the sudden setting...
Numerical modelling of the tide-induced residual current in the East China Sea
Tang Yuxiang
1989, (2): 179-190.
Abstract:
A two-dimensional.nonlinear numerical model is used to study the residual current generated by tides in the East China Sea (ECS) and the South Huanghai Sea (SHS). At first, the principal semidiurnal lunar tide (M2) and the tidal current are derived i...
A calculation method of the sensible heat flux by sodar
Lu Naiping, Li Shiming, Chen Jingnan, Zheng Yueming, Zhou Mingyu
1989, (2): 191-198.
Abstract:
During the second course of USA-PRC joint air sea interaction experiment in 1986, the temperature structure parameters CT2 were measured by sodar over the Western Pacific Ocean. Based on similarity theory, a method is discussed to calculate the sensi...
A comparison analysis between developed and undeveloped depressions over the South China Sea
Liang Biqi, Zhang Qiuqing
1989, (2): 199-208.
Abstract:
In this paper, by using two sets of composite data of developed and undeveloped depressions over the South China Sea, we analyze and compare the dynamic structures, the heating fields and the vorticity budget residuals of two different types of depre...
The effects of the intertropical convergence zone on the easterly jet stream during Northern summer
Xu Liang, Bao Chenglan
1989, (2): 209-215.
Abstract:
In this paper, a strong lTCZ process and an lTCZ-absent process during FGGE in 1979 were selected for comparison to explore how they were subject to the influence of the evolution of the upper easterly jets.
The strong winter monsoon in East Asia and El Nino
Gao Shiying, Wang Jinshu
1989, (2): 217-221.
Abstract:
The relationship between meridional wind in mid-latitudes of East Asia and SST in the Equatorial Eastern Pacific is analysed in this paper. It is pointed out that there exist close relations between the seasonal changes of the meridional wind in mid-...
A study on chemical forms of heavy metals in the sediments of Zhujiang River and its estuary
Zheng Jianlu, Lin Zhiqing, Chen Yang
1989, (2): 223-235.
Abstract:
The five chemical bound forms of Fe, Al and Mn in sediments in the main channel of the Zhujiang River.and its estuary, namely, exchangeable, carbonic, oxidative, organic and residual (in crystal) forms, were determined. The method of sequential extra...
Toxic chemistry of heavy metals on Isochrysis galbana (parke)in inshore water
Zheng Zhihong, Liu Shizhong, Wu Yuduan
1989, (2): 237-251.
Abstract:
Effects of heavy metals on Isochrysis galbana (Parke) were studied in our laboratory. The research focused on toxic effects of metals on algal cells, effects of water-soluble and lipid-soluble organic ligands on metal toxicity and processes of metal ...
Radiochemical studies of deep-sea manganese nodules
Huang Yipu, Luo Shangde, Shi Wenyuan, Chen Zhen
1989, (2): 253-261.
Abstract:
Five manganese nodules collected from the Northern Mid-Pacific have been analysed for their U and Th isotopes.It is found that the enrichment of thorium compared to uranium is universal in deep-sea manganese, nodules and in the top sides of the nodul...
Study of radioactive status in the Zhujiang Estuary and adjacent sea area in South China Sea (SCS)
Liu Huai, Su Xiling, Chen Chi, Gou Min, Liang Qianlin
1989, (2): 263-272.
Abstract:
Through the investigation on radioactive activities of water, sediment and some marine organismsin the Zhujiang Estuary, adjacent sea area and the distributary mouths of the Zhujiang River, activities of total α. radioactivity, total β radioactivity,...
Relationship between suspended sediments from the Changjiang Estuary and the evolution of the embayed muddy coast of Zhejiang Province
Cao Peikui, Hu Fangxi, Gu Guochuan, Zhou Yueqin
1989, (2): 273-283.
Abstract:
South of Hangzhou Bay, Zhejiang Province, exhibits an embayed muddy coastline, with the muddy beaches of embayments extending continuously seaward.The source of sediments on this coast presents an interesting problem to marine geologists and geomorph...
Study of fouling organisms at Tuoji Island in the Bohai Channel
