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 ". 相似文献

根据“中美热带西太平洋海-气相互作用联合考察”1—8航次考察资料、美国NOAA、日本气象厅及我国国家气象中心气候资料室提供的SST、水位和风场等资料,对1988—1989年反厄尔尼诺事件(La Nina)形成及发展过程和热带西太平洋海洋上层热结构的相互变化作了综合分析。文章指出在La Nina事件期间,热带太平洋的海、气参数均发生了相应的变化。热带西太平洋温跃层及热含量(0—150m)作出的响应,显示出当La Nina增强时,温跃层下降,热含量增加;La Nina盛期时,温跃层最深,热含量最大;La Nina减弱时,温跃层上升,热含量减小。它们与厄尔尼诺事件(El Nino)的关系则恰好相反。 相似文献

In this paper the relationship between the variation of shrimp resources (which is sensitive to the sea temperature of the Huanghai and Bohai Seas) and the equatorial sea surface temperature is analysed, the results obtained showing high correlation between the two. Therefore, a new approach to studying long-term variational law of fishery resources and forecasting method is made through large-scale air-sea interaction. 相似文献
