%X The time series rainfall data of 8 stations in North China are analyzed by using the wavelet transform. From the 100 years data, approximate 6- 7 years, 21-22 years and 35 - 36 years periods are found respectively. The results provide important information for approaching the predictability of sec- ular xerasium trend in North China. The reconstruction from these canonical scale curves is carried out. Consequently, the main feature of reconstructed curves agrees with the initial data curves.
