积云的清除作用与其酸化的数值模拟
Numerical Simulation of Scavenging aud Acidification in Cumulus Clouds
【摘要】 一维时变参数化积云模式与污染物浓度连续方程相结合,根据积云内外SO2和HNO3浓度、云水S(VI)浓度、H2O2和O3的氧化速率以及地面雨水S(VI)浓度的时空变化,分别讨论核化清除、液相氧化、云下气溶胶清除、碱性气溶胶、云外污染物的夹卷以及SO2初始分布等因子的重要性。
【Abstract】 A 1-D time-dependent and parameterized cumulus model, combined with continuity equations of pollutants, is used to calculate concentrations of SO2 inside and outside cumulus, spatial and temporal distribution of S(VI) concentration in cloudwater, oxidation rates of H2O2 and O3, S(VI) concentration in rainwater at the surface. Based on the model calculated results, the importance of various factors such as the nucleation scavenging, aqueous oxidation, subcloud scavengiing of aerosols, basic aerosols,entrainment and SO2 initial distribution is discussed.
