摘要
将大气化学模式引入到区域气候模式中 ,实现同步计算大气化学成分和气象要素 ,以中国地区 1994年 1、4、7、10月为研究对象 ,模拟了 4个月的气候变化 ,通过分析发现 :硫酸盐气溶胶的直接和间接辐射效应都使大气顶产生负的辐射强迫 ,使地面气温下降 ;间接效应的引入加剧了辐射强迫和地面降温 ,是一个不可忽视的重要过程 。
A regional climate model coupled by an atmospheric chemistry model was used to simulate sulfate aerosol and climate over China area.The direct and indirect radiative effects of sulfate aerosol were also explored.The results showed that the sulfate aerosol will cause negative radiative forcing on the top of atmosphere, and also decrease the surface air temperature.Based on the comparison between the direct effect and the indirect effect, it is obvious that to improve modeling the direct and indirect effects of sulfate aerosol should be included in the model system.
