International Journal of Climatology, EarlyView.Future runoff in China shows strong regional and seasonal disparities, with the Southeast basin seeing the largest increase in annual runoff. Wetter summers and drier winters are expected in the south, whilst the northwest will face the opposite. Over 56% of regions are expected to experience more extreme high runoff, and over 40% face intensified low ...
