成云过程中云水pH值的参数化

A Study of Parameterization for pH of Cloud

    摘要
  • 摘要: 该文找出了影响云水pH值的主要因素,用统计分析的方法得到它们与云水pH值之间的简单的函数关系。通过参数化研究发现,在一定的变量取值范围内,模式模拟的结果与用函数关系式得到的结果能很好地对应起来,相关系数为0.94。该文参数化所考虑的变量为:气相H2O2,O3,SO2与NH3的浓度,液相Fe3+与Mn2+的浓度,水的含量及温度。

     

    Abstract: In this study,the main factors which influence pH of cloud were found,and their simplified functional connection was got by using statistical analysis.The results of model simulation agree well with the calculated results from formulate within the limits permitted of variable.The coefficient is 0.94,and the concentration of gas phase H2O2,O3,SO2 and NH 3,liquid phase Fe3+and Mn2+,H2O and temperature were taken into consideration when parameterization was made in this study.
