Abstract:
In this paper, the analysis of net volume of the Kuroshio in PN section of the East China Sea, the calculations of volume transports of the North Equatorial Current (NEC) and North Equatorial Countercurrent (NECC) and the upper layer heat content (0～150 m) in 137°E section during 1967-1992,and the sea surface temperature anomaly (SSTA) in the northern Pacific are illustrated. Meanwhile,the long term variation of subtropical high in northern hemisphere and in the western Pacific, and atmosphere oscillation are also analyzed. By using Mann-Kendall method, the verification shows that the ocean condition and atmospheric circulation system mentioned above all presented "climate transition"during the mid-and late-Stage of 1970's, that is, the volume transports of the Kuroshio, the NEC and the NECC varied from weak to strong; the SSTA changed from the type of La Nina to that of E1 Nino,which were coincident with atmospheric circulation system, i. e. the subtropical high in northern hemisphere and in the western Pacific, and atmospheric oscillation all had the feature of changing from weak to strong, which indicated the response of atmospheric "climate transition" to oceanic "climate transition ".
