In this paper, the sea-air heat exchange over the Kuroshio in the East china Sea during the winters of 1954-1972 is computed and analysed. The results indicate that the year to year anomalies of sea-air heat exchange are obvious and the values are mainly controlled by the intensity of the cold air at the same time. The authors have found a close relationship between sea-air heat exchange and precipitation in the region of the Changjiang River during the early summer. Finally, the predicting indication for forecasting this precipitation around the middle and lower reaches of Changjiang River in June is given.

The major aim of this study is to put forwad a valid model to explain the-gravity anomalies observed over the Okinawa Trough which the crustal structure and a reasonable model of the downgoing slab themselves cannot explain. The result of inversion indicates that the lithosphere above the center of the trough thins out to 45% of the normal thickness (63 km) of the lithosphere of the East china ***, the originations of lithospheric force are discussed. The tensional stress of about 160 bar arising from density contrast in the Okinawa Trough is recognized to be the most important causative factor in the stretching of the trough.

Based on the current measurement data from the R/V Ryofu Maru of JMA in the equatorial area along 137°E (1972-83) and 155°E (1972-79) the structures of the zonal velocity of the Equatorial Undercurrent (EUC) and the North Equatorial Countercurrent (NECC) and their variations are systematically analyzed in *** 155°E, the current at the equator and 100-300 m depth was a typical eastward EUC, it intensified in 1973-75, i.e., in the non-El Nino period. While the corresponding current at 137°E was mostly westward, and the origin of the EUC shifted to north of the equator around 0.5-1.5°N owing to the influence of the New Guinea Coast. The EUC origin disappeared in early July, 1982. Comparing with the EUC disappearance at 159°W, the average speed of an eastward travelling wave would be~1.1m/*** velocity core of the NECC at 137 E generally shifted northward in winter and southward in summer, and was stronger in summer and weaker in winter. The fluctuations of the NECC were closely related to thos

One of the difficulties in dealing with wind-driven current in coastal sea is the determination of sea surface slope because the governing equation is so complicated a differentialintegral equation that only a general numerical solution can be obtained. Hidaka (1954) discussed the current in an infinite deep sea. Li Xinming et al. (1965) treated the case with constant depth but the surface slope effect on current was not considered. In 1971, making a series of approximations based on physics, Garvine (1971) obtained some important results. Problem like that of Garvine was dealt with by Fourier transforms in this paper. Because in Fourier image space the governing equation, of surface slope is a simple algebraic equation, so that the question was reduced to getting the inverse Fourier
