Abstract
OCCAM global ocean model results were applied to calculate the monthly water transport through 7 straits around the East China Sea (ECS) and the South China Sea (SCS). Analysis of the features of velocity profiles and their variations in the Togara Strait, Luzon Strait and Eastern Taiwan Strait showed that: 1) the velocity profiles had striped pattern in the Eastern Taiwan Strait, where monthly flux varied from 22.4 to 28.1 Sv and annual mean was about 25.8 Sv; 2) the profiles of velocity in the Togara Strait were characterized by core structure, and monthly flux varied from 23.3 to 31.4 Sv, with annual mean of about 27.9 Sv; 3) water flowed from the SCS to the ECS in the Taiwan Strait, with maximum flux of 3.1 Sv in July and minimum of 0.9 Sv in November; 4) the flux in the Tsushima Strait varied by only about 0.4 Sv by season and its annual mean was about 2.3 Sv; 5) Kuroshio water flowed into the SCS in the Luzon Strait throughout the year and the velocity profiles were characterized by multi-core structure. The flux in the Luzon Strait was minimum in June (about 2.4 Sv) and maximum in February (about 9.0 Sv), and its annual mean was 4.8 Sv; 6) the monthly flux in the Mindoro Strait was maximum in December (3.0 Sv) and minimum in June (only 0.1 Sv), and its annual mean was 1.3 Sv; 7) Karimata Strait water flowed into the SCS from May to August, with maximum inflow flux of about 0.75 Sv in June and flowed out from September to April at maximum outflow flux of 3.9 Sv in January. The annual mean flux was about 1.35 Sv.
