Interannual and interdecadal variability of winter precipitation over china in relation to global sea level pressure anomalies
Based on the method of rotated principal component (RPC) analysis and wavelet transforms, the winter precipitation from 36 stations over China for the period 1881-1993 is examined. The results show that the th...
