地球自转参数变化引发大气、洋流变化,因此本文试图探索西太平洋气旋频数、强度与地球自转参数的相关性,结果表明:日长月平均值与下一月气旋频数呈正比,章动月标准差与下一月气旋强度相关性较好;频数与强度极端年份的日长、章动逐日变化有显著差异,频数最大值年与最小值年对应的日长位相呈明显的反相,相位若接近同步,则大值年对应的日长明显大于小值年;频数极端年份4-6月章动的位相差异明显,7-9月章动幅度差异明显;强度极端年对应的前30天逐日日长呈非常显著的反相关系,x方向章动具有明显差异,大值年的x方向章动值均偏小.
Therefore, this paper attempts to explore the correlation between the frequency and intensity of cyclone in the western Pacific and the rotation parameters of the Earth. The results show that the daily mean of long-term is proportional to the frequency of next-month cyclone, And the correlation between the cyclone intensity and the intensity of the next month is good. The daily variation and the nutation variation of the frequency and intensity are significantly different. The daily phase corresponding to the year of the maximum frequency and the minimum value are obviously inverted, The maximum daily value corresponding to the large-value year is obviously larger than the small-value year; the phase difference of the nutation is obvious from April to June in the extreme years of frequency, and the amplitude of the nutation amplitude is obviously different from July to September; Long significant inverse relationship between the significant changes in the x-direction nutation, the value of the year x-axis nutation values are small.
