摘　　要：本文利用最大熵谱分别计算了南极４个区海冰和西北太平洋台风发生频数的变化周期，并对前３年的南极海冰强弱和当年的台风发生频数进行了逐月时间序列相关分析。从初步分析结果中得出一些比较有意义的结论，南极海冰前１年海冰多，则北半球西北太平洋台风发生频数就会高，以罗斯海域为主体的Ⅱ区海冰与北安心西北太平洋台风发生频数无关。Both the variation Periods of Antarctic sea-ice in four regions and the Typhoon occuring in northwest Pacific over North Hemisphere is analyzed with the method of maximum entropy spectrum. The monthly time-series correlations between the Antarctic sea-ice during three years ealier and Typhoon occurrenec frequency in current year, are analyzed. Some quite significant results are obtained. If the Antarctic sea ice during 1 year ealier was more, the frequency of the Typhoon occurring on northwest Pacific in current year was higner. In region Ⅱ which is dominated by Ross Sea, ice intensity does, not relate to the frequency of the Typhoon occurrence.
