2000, 22(4): 1-7.
Abstract:
In order to provide more accurate initial field for numerical predict of the sea temperature the adjoins method is used to assimilate the sea temperature observations into one-dimensional sea temperature model in this paper.How to establish the adjoi...
Large scale characteristics of interannual variability of sea surface temperature in the South China Sea
Wang Weiqiang, Wang Dongxiao, Qi Yiquan
2000, 22(4): 8-16.
Abstract:
The marine meteorological data in the South China Sea(SCS) which were derived from COADS are analyzed.The results indicate that interannual variability of sea surface temperature(SST) in the SCS holds a quasiperiodical feature.There is a so-called ph...
The spectrum analysis of discharge and salinity in the Changjiang Estuary

2000, 22(4): 17-23.
Abstract:
The spectrum analysis is applied to analyse the fluctuations of the discharge and salinity, the characteristics of correlation between salinity and discharge in the Changjiang Estuary.The results show that the quasi-periods of discharge include 4.0-8...
The influence of diabatic heating on tropical cyclone radial inhomogeneity structure
Lei Xiaotu
2000, 22(4): 24-30.
Abstract:
Decomposing the Tropical cyclone asymmetric disturbance into the superposition of the symmetric environmental circulation, the travelling wave analytical solution is given by using the barotropical non-divergent model with diabatic heating forcing an...
A new type of shipboard meteorological satellite receiving-processing system

2000, 22(4): 31-40.
Abstract:
The shipboard meteorological satellite receiving一processing system(SMSRPS) is specially developed for the navigation meteorological safeguard of the Antarctic exploration ship over the sea ice area of the Southtrn Ocean.This system can suit to the cl...
Higher-order Boussinesq equations with strong currents
Zou Zhili
2000, 22(4): 41-50.
Abstract:
The higher-order Boussinesq equations for the case of strong current are developed by a perturbation method under the assumption that the current velocity is of the same magnitude as the wave group velocity, and its time and space scales of variation...
The study on aging index of upwelling by the contents of several species phosphorus
Chen Shuitu
2000, 22(4): 51-59.
Abstract:
The results from the Minnan-Taiwan Bank fishing ground upwelling ecosystem study during the period from December 1987 through November 1988 and from the upwelling study of the central and northern Taiwan Strait in July 1987 to July 1988 show that the...
Nutrient limitation of phytoplankton in the Changjiang Estuary──Ⅰ. Condition of nutrient limitation in autumn
Pu Xinming, Wu Yulin, Zhang Yongshan
2000, 22(4): 60-66.
Abstract:
During November 20-22, 1998, samples were collected at two stations in the Changjiang Estuary.The nutrients limiting algal growth potential(AGP) are estimated by ratios of dissolved inorganic N to P and by nutrient enrichment bioassays using Skeleton...
Phytoneuston in the southern Taiwan Strait
Huang Jiaqi, Li Shaojing, Yu Yao
2000, 22(4): 67-73.
Abstract:
During the period of June and November 1988 samples were collected by the improved Manta neuston net at 18 stations in the southern Taiwan Strait.102 species of phytoneuston are identified.Total individuals of phytoneuston in June are more abundant t...
