| Abstract: | An introduction was made on the calculating theory of periodic wave mean superposition method.Based on the annual precipitation data from 1952 to 2006 recorded by Mei county rainfall station and Chaoan station located in Hanjiang river basin,periodic wave mean superposition method was applied to analyze the rainfall variation rule,then the obtained periods were separately extended before linear superposition for predicting the annual precipitation of Mei county and Chaoan rainfall stations from 2007 to 2009,of which the prediction result from 2007 to 2008 is within the tolerance. |
