通过分析北太平洋信风场风应力资料,可以发现,太平洋中两个最引人注目的海洋现象——黑潮大弯曲和埃尔尼诺都与北太平洋上空风应力涡度的变化和大气热带辐聚带的南北移动有关。埃尔尼诺的发生对应着大气热带辐聚带的南移和热带气旋式风应力涡度的增强;而黑潮大弯曲的形成则发生在该辐聚带的大幅度北移和副热带反气旋式风应力涡度迅速衰弱之时。可以说,黑潮大弯曲和埃尔尼诺不是彼此孤立的,而是同一个大尺度海气系统变化的反映。
By analyzing the wind stress data in the North Pacific Wind Field, it can be found that the two most striking ocean phenomena in the Pacific - the large Kuroshio and El Niño wind vorticity changes over the North Pacific and the atmospheric tropics Radiation convergence with the North-South movement. The occurrence of El Niño corresponds to the southward shift of the tropical tropic zone and the increase of the tropical cyclone wind stress vorticity. The formation of the large Kuroshio bend occurs during the significant northward shift of the convergence zone and the subtropical anticyclone The wind-induced eddy vortex declines rapidly. It can be said that the Kuroshio bend and El Niño are not isolated from each other, but a reflection of changes in the same large-scale air-sea system.
