本文根据北太平洋西南部分1965—1974年冬季的水文资料及附近区域1975—1983年月平均水位资料,比较详细地探讨了棉兰老冷涡的变异及其是否与El Ni(?)o事件有关的问题。结果表明,棉兰老冷涡的变异与El Ni(?)o有着密切的关系,在El Ni(?)o期间,棉兰老冷涡变得较强;而在非El Ni(?)o期间,冷涡变得较弱。然而,冷涡强化的程度并非总与ElNi(?)o的强度相对应。这显然是由于El Ni(?)o仅是影响或控制冷涡变化的主要因素之一而已。
Based on the winter hydrological data from 1965 to 1974 in the southwestern part of the North Pacific Ocean and the monthly mean water level data from 1975 to 1983 in the vicinity of the North Pacific Ocean, this paper discusses in more detail the variation of the Mindanian cold vortex and whether it is related to the El Niño event problem. The results show that the variation of the Old Mindanao vortex is closely related to El Ni (?) O during the period of El Ni (?) O, Cold eddy becomes weaker. However, the degree of cold vortex strengthening does not always correspond to the strength of ElNi (?) O. This is obviously because El Niño is only one of the main factors that influence or control the change of cold eddy.
