Multiscale Variability of the River Runoff System in China and Its Long-Term Link to Precipitation and Sea Surface Temperature

摘要: Abstract This is an exploratory study to investigate the spatial and temporal characteristics of east China’s (EC) river runoff their relationship with precipitation sea surface temperature (SST) at continental scale. Monthly mean data from 72 stations 160 in EC, covering a period between 1951 1983, are used for this study. The station have been spatially interpolated onto 1° grid boxes as depth based on extracted drainage network. Comparing shows that seasonal variation consistent development summer monsoon, including delayed response several subregions. dominant scales patterns studied empirical orthogonal function (EOF) analysis wavelet analyses. analyses show interannual, biennial, longer-term variations EOF modes.
