| Abstract: | Summary The Runoff of the Changjiang River and the Huanghe River were investigated with the method of wavelet transform. Several significant periods were found. Comparison between wavelet analysis and Fourier analysis was made, which shows the advantages of the former. Finally, the application of the wavelet analysis to operational prediction is discussed.This study is supported by the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics (LASG), Chinese Academy of Sciences.With 6 Figures |
