The water cycle over the Tibetan Plateau (TP), known as the "Asian Water Tower", is vital to the regional and downstream climate and ecosystem. A new study found that the interannual variability of the summer precipitation recycle ratio over the TP is influenced by the El NIño events in preceding winters. The study was published in Journal of Geophysical Research: Atmospheres and conducted by researchers from the Institute of Atmospheric Physics at the Chinese Academy of Sciences.
