降水过程中氢氧稳定同位素理论关系研究

Theoretical research on the relationship between deuterium and oxygen 18 in precipitation

  • 摘要: 大气降水过程中氢氧稳定同位素比值呈现一定的规律,分析了瑞利分馏中分馏系数的影响因子,基于瑞利分馏原理和质量守恒定律,分别推导了开放系统和封闭系统降水过程中的稳定同位素微分方程模型,研究了大气降水过程中氢、氧稳定同位素变化规律,导出了云团水汽和降水氢、氧之间的相互关系,结果表明这一关系并非简单的线性关系。

     

    Abstract: The relationship between deuterium and oxygen 18 in atmospheric precipitation shows the certain law.This paper analyaes the impact factors for fractionation coefficient in Rayleigh fractionation,gives the differential equation models of stable isotope composition in precipitation in the open system and closed system,and discloses the variation law of deuterium and oxygen 18 in precipitation.And the relationship between deuterium and oxygen 18 in precipitation and clouds vapor is deducted.The result shows that it is not simply linear relation between the deuterium and oxygenl8 in precipitation.
