| Abstract: | Using the singular spectrum analysis method,the annual rainfall data from 1951 to 2006 in Zhengzhou is analyzed.The results show the variable tendency of the annual rainfall is not obviously;main wave oscillation periods are 9,7,5 and 3 a.There is inter-decadal change among the oscillation periods and each period strong or weak shows dissimilarity. |
