| 摘 要： | 假定形成在硫酸盐和硝酸盐等核上的云滴溶解了酸、碱性气体,在很短时间内达到气液平衡,本文在先前的数值模式计算基础上,考虑大气中H_2O_2和O_3对SO_2的氧化过程对云水酸化的作用,并考虑云内液态含水量的改变对云水酸度的影响。计算结果表明:大气中SO_2的氧化过程对云水酸化的作用是不能忽视的,H_2O_2是一种比O_3更有效的氧化剂,而云中液态含水量改变对云水酸化的贡献相对地较小。

| Abstract: | It is assumed that the cloud droplets formed on sulfate and nitrate and other nuclei dissolve acidic and alkaline gases to achieve gas-liquid equilibrium in a very short time. In this paper, the considerations that oxidative process of SO_2 by H_2O_2 and O_3 in the atmosphere contributes to acidification of cloud water and that the change of liquid water content in cloud effects on acidity of cloud water are based on precedent the calculation of numerical model of acidification of cloud water. The result from calculations shows that the oxidative process of SO_2 in the atmosphere can not be negligible for the acidification of cloud water, that H_2O_2 is an oxidant stronger than O_3, and that the change of the liquid water content in cloud contributes relatively less to the acidification of cloud water. |
