Abstract The recent warming hiatus started around 1998; however, how Central Asian river streamflows have responded to this warming slowdown remains unclear. Based on the instrumental streamflow records of eight rivers in Central Asian, we showed that the Central Asian streamflow variation is due to the change in precipitation/drought resulting from sea surface temperature changes in the eastern tropical Pacific Ocean and that equatorial eastern Pacific surface cooling has been the main driver of the slowdown in streamflow increase in Central Asia over the past two decades. Temperature is also likely an important driver of streamflow variation on the Pamirs Plateau during the warm season; however, the linkage between temperature and streamflow is not stable due in part to the precipitation-induced cooling. Central Asian river streamflow is very sensitive to variations in climate factors, and the influences of climate change on streamflow should be considered continuously by water resource managers.

在最近的变暖中断期间,中亚河流的流量没有继续增加

摘要 最近的变暖中断始于 1998 年左右;然而,中亚河流流量如何对这种变暖放缓做出反应仍不清楚。基于中亚8条河流的仪器水流记录,我们发现中亚水流变化是由于热带太平洋东部海面温度变化引起的降水/干旱变化,赤道东太平洋表面冷却造成的。是过去 20 年中亚流量增长放缓的主要驱动力。温度也可能是暖季帕米尔高原水流变化的重要驱动因素;然而,温度和水流之间的联系并不稳定,部分原因是降水引起的冷却。
