对地球冰川时期降水的代理重建和模型模拟表明，大气水分输送的位置和机制在地球过去发生了很大变化。我们使用共同体地球系统模型的模拟来研究末次冰川盛期(LGM)的水气候，重点是温带外和大气河流(Ars)的影响，大气河流(Ars)是现代全球水汽输送的关键驱动因素。巴塔哥尼亚西南部、伊比利亚和北美西南部--现代气候中受ARS影响的中纬度地区--的平均和极端降水量显著增加，尽管其他地区总体上有所下降。两者的水汽输送变化是不同的，输送增加和AR活动主要发生在北大西洋。总体上，盛冰期的响应主要是对冰盖的响应，其他强迫作用导致温带以外地区的额外冷却和干燥，以及亚极地北大西洋上空的水汽输送的强烈减少。
Proxy reconstructions and model simulations of precipitation during Earth's glacial periods suggest that the locations and mechanisms of atmospheric moisture transport have changed considerably during Earth's past. We investigate the hydroclimate of the Last Glacial Maximum (LGM) using simulations with the Community Earth System Model, with a focus on the extratropics and the influence of atmospheric rivers (ARs), a key driver of modern‐day moisture transport globally. Mean and extreme precipitation increase significantly over southwestern Patagonia, Iberia, and southwestern North America—mid‐latitude regions affected by ARs in the modern climate—despite overall decreases elsewhere. In each, the associated moisture transport changes are different, with increased transport and AR activity mainly occurring in the North Atlantic. The overall LGM response is dominated by the response to ice sheets, with other forcings causing additional cooling and drying over the extratropics and a strong decrease of moisture transport over the subpolar North Atlantic.
