Abstract: | In this paper, annual and seasonal-precipitations in China are classfied by the fuzzy systems cluster method, A method used to find out the correlation coefficient within a certain class is given for objectively expressing of interclass correlation level. A principle for selecting of precipitation classification scheme is put forward. The results are satisfactory. |
