The equilibrium range of wind wave frequency spectrum
Wen Shengchang(S. C. Wen), Zhang Dacuo, Chen Bohai, Guo Peifang
1990, (1): 1-11.
Abstract:
Theoretical form of equilibrium range is given on the basis of the wind wave frequency spectra proposed by Wenel al.(1988a,b,c, 1989a,b).The effects of peakness factor and water depth are discussed.In the case of deep water the e-quilibrium range is ...
Combined refraction and diffraction models for sea waves over complicated topography and with currents in shallow water
Yin Baoshu, Jiang Decai
1990, (1): 13-23.
Abstract:
Combined refraction and diffraction models in the form of linear parabolic approximation are derived through smallparameter method.More strictly theoretical basis and more accuracy in the models than Lozano's (1980) are obtained.Some theoretical defe...
Seasonal responses of monthly mean sea levels in the Bohai Sea to hydrometeorological forcing and their double screening regression models
Chen Shangji, Ma Jirui, Yu Jiye
1990, (1): 25-35.
Abstract:
In this paper, the maximum entropy spectral, the cross-spectral and the frequency response analyses are madeon the basis of the data of monthly mean sea levels at coastal stations in the Bohai Sea during 1965-1986.The results show that the annual flu...
Nonlinear tidal waves in a kind of estuary with gradually varying cross-section
Du Yong, Chen Zongyong, Ye Anle
1990, (1): 37-50.
Abstract:
Nonlinear tidal waves in a kind of estuary are studied in the paper using one-dimensional nonlinear hydrody-namic equations with friction.The estuary has exponentially varying width B=B0e-bx and uniform depth h.The one-dimensional hydrodynamic equati...
Marine Meteorology
The numerical criteria and characteristics of El Nino and La Nina
Wang Shiping
1990, (1): 51-59.
Abstract:
By using the sea surface temperature (SST) index of the Equatorial Pacific Ocean provided by Climate Analysis Center of U.S.A., the numerical criteria of El Nino and La Nina events and their quantitative characteristics were calculated.Results show t...
Threshold autoregression models for forecasting El Nino events
Pu Shuzhen, Yu Huiling
1990, (1): 61-67.
Abstract:
In this paper, monthly mean SST data in a large area are used.After the spacial average of the data is carried out and the secular monthly means are substracted, a time series (Jan.1951-Dec.1985) of SST anomalies of the cold tongue water area in the ...
The computation of maximum wind speeds of typhoon
Chen Kongmo, Qin Zenghao
1990, (1): 69-79.
Abstract:
At present, it is still difficult to obtain an accurate maximum wind speed of typhoon with modern means,such as satellite survey, radar tracing and airplane reconnaissance.The performance of statistical equation established with observational maximum...
Marine Chemistry
Preliminary study on the distribution of nutrients, organic matter, trace metals in sea surface microlayer in Xiamen Bay and Jiulong Estuary
Hong Huasheng, Lin Jie
1990, (1): 81-90.
Abstract:
The enrichment of nutrients (NO2-, NO3-, PO43-), suspended particles, organic matter (POC, PON,DOC), and trace metals (Cu, Ni, Cd) was determined in the sea surface microlayer of Xiamen Bay and Jiulong Estuary.The mean enrichment factors ([Xi]microla...
Adsorption of uranyl complex ions on hydrous titanium oxide (HTO)——Ⅱ. Infrared spectrum investigation
Fu Wentong, Luo Bingkun
1990, (1): 91-96.
Abstract:
The i.r.spectra of Na4[UO2(CO3)3], Na[UO2(OH)3] and the surface species of uranium on HTO underthe condition of flowing natural seawater and concentrated seawater (NaCl-NaHCO3-U) were recorded, with the bands of uranyl of surface species obtained and...

Hu Binghuan, Chen Wending, Lin Jinhuo, Zhao Fang, Gan Jinghao
1990, (1): 97-107.
Abstract:
The present paper reports a new type of coating possessing with excellent anticorrosive properties for marine application.The coatings are urushiol-titanium chelate polymer.The present authors list the anticorrosive spectra of the new coating in vari...

Chen Shaoyong, Li Wenquan, Shi Wenyuan, Huang Yipu
1990, (1): 109-117.
Abstract:
The applicability of the doubie-layer model for 210Pb chronology in coastal marine environments was discussed,which is successfully used in the study of mixing rates and sedimentation rates in Meizhou Bay.Differences among sedimentation rates deduced...
