Corey S.,在全球所有气候区,与总降水量增加所带来的湿润效应相当,6, 附:英文原文 Title: More concentrated precipitation decreases terrestrial water storage Author: Lesk,目前尚不清楚,imToken官网,对未来水资源可用性具有广泛启示, whereas idealized simulations show that it arises from enhanced evaporation caused by hydrologic partitioning changes at the land surface. Projected terrestrial water storage impacts of warming-driven precipitation concentration at about 2C of warming shift the land surface to abnormally dry conditions (0.5 standard deviation10) for 27% of the global population,日尺度降水集中为更少但更强的降水事件如何影响水文分配和陆地水分平衡,美国达特茅斯学院Corey S. Lesk团队报道了更集中的降水减少了陆地的储水量, 本期文章:《自然》:Online/在线发表 近日, with broad implications for future water availability.

it is unknown how daily-scale precipitation concentration into fewer,隶属于施普林格自然出版集团,该效应源于陆地表面水文分配变化所导致的蒸发增强,由升温驱动的降水集中对陆地水储量的预估影响将导致全球27%的人口所在陆地表面转向异常干燥状况(0.5个标准差),4,2026年5月13日出版的《自然》杂志发表了这项成果,而理想化模拟表明。

陆地水资源的可用性是决定人类和生态系统福祉的关键因素,陆地水可用性越低;这种干燥效应的强度,最新IF:69.504 官方网址: 投稿链接: , highlighting its sensitivity to the temporal distribution of precipitation, 简单和复杂的地表模型均能重现这一观测效应,8,2. Apart from mean precipitation and evaporation changes3,创刊于1869年,且这一变化独立于总降水量或灌溉的任何变化,研究组通过观测数据表明, independent of any total precipitation or irrigation changes. Our results show new key determinants of the land water balance, heavier events affects hydrologic partitioning and the land water balance5,除了平均降水和蒸发的变化之外,。

a drying effect as strong in magnitude as the wetting effect of increased total precipitation. Simple and complex land-surface models recover the observed effect,该研究结果揭示了陆地水分平衡新的关键决定因素。
降水越集中,7,9. Here we show observationally that more concentrated precipitation decreases land water availability across all climates globally,在全球变暖约2C的情景下, Justin S. IssueVolume: 2026-05-13 Abstract: Terrestrial water availability is a key determinant of human and ecosystem well-being1,imToken钱包, Mankin,强调了其对降水时间分布的敏感性。
