第一次调查结果展示了全球地表岩层透水性的分布,从图中可以看出,总体上来说透水性能较高的区域占了较大比例,制作这张图的是加拿大范库弗的不列颠哥伦比亚大学水文地质学博士后托姆格里森。这张图的意义在于:过去的气候预测模型中并没有考虑地下水的运动影响,而这张图展示了占全球99%的不冻淡水的循环区域,而这些地下淡水的存在对当地的气候影响是不可忽视的。它将帮助人们更好地处理气候预测和理解自然淡水的循环过程。 不过,我和一位读者有着同样的问题:“If "we don't know how much water is hiding underground", how do we know it "makes up 99% of all fresh unfrozen water"? Just asking...”
The map is a "very good first step", says Richard Taylor of University College London. However he says the figures for North America are the most reliable, because that area has been heavily studied, whereas those for the rest of the world are more scanty.Journal reference: Geophysical Research Letters, DOI: 10.1029/2010GL045565

That huge store could somehow modulate the climate. There may be really complex interactions that we don't appreciate.”The map is a "very good first step", says Richard Taylor of University College London.
