Abstract

Abstract

The volume transports of the North Equatorial Current (NEC),the Kuroshio (KC),and the Mindanao Current (MC) along the Pacific western boundary were investigated through traditional dynamical method by using long-time and high-resolution data set. The results show that the volume transports of the NEC and KC exhibited similar distinct inter-annual and inter-decadal variations. Both of them experienced a climate jump in 1976 and bear obvious intensifying trends after 1976. In contrast,the transport fluxes of the MC transport is different from that of the NEC and KC. It seems that the increased volume of the NEC mostly flows into the KC rather than the MC after 1976. The correlation analysis suggests that inter-annual variations of the NEC transport may be also greatly influenced by Rossby Wave and Mindanao cyclonic eddy.
