Abstract

Stable isotopes of water molecules in hydrology, the water cycle and Craig's global meteoric water line (GMWL) relating δ(18)O and δ(2)H are well established with a slope of around 8 and an intercept of around 10. However, in many situations the slope is less than 8 and the intercept is smaller or even negative. These observations need to be understood and a method is suggested to correlate with the global meteoric water line (GMWL). How to find the isotopic composition of water at a particular place is also suggested.

摘要

在水文学、水循环以及与δ(18)O和δ(2)H相关的克雷格全球大气降水线（GMWL）中，水分子的稳定同位素已得到充分确立，其斜率约为8，截距约为10。然而，在许多情况下，斜率小于8，截距更小甚至为负。需要理解这些观测结果，并提出一种与全球大气降水线（GMWL）相关的方法。还建议了如何确定特定地点水的同位素组成。
