Summertime ENSO potentially amplifies rainstorm and flood risk in the lower Yellow River Basin, China
Study region: The Yellow River Basin (YRB) in China. Study focus: Ecological conservation and high-quality development of the YRB have been incorporated into the national strategy of China. Here we investigated into the impacts of El Nino-Southern Oscillation (ENSO) on rainstorm and flood risk in th...

Study region: The Yellow River Basin (YRB) in China. Study focus: Ecological conservation and high-quality development of the YRB have been incorporated into the national strategy of China.
