为学习在地区性的规模上的人为的硫酸盐和气候的反应的放射的强迫的三个主要方法,与为到硫酸盐的 transformingSO_2 的给定的率,第一把实际上释放的 SO_2 正在变换成硫酸盐并且由在气候模型计算转移方程获得硫酸盐的分发。第二在在网上结合的地区性的气候模型通过事的化学反应和转移正在获得硫酸盐分发为硫化物包括完整的化学反应的一个大气的化学模型。Thethird 是把硫酸盐分发数据放从 GCM 和它的联合大气的化学模型到地区性的气候模型,它是因此调用了离线的联合方法。是出现在比较在之间在网上并且脱机在地区性的规模上当模特儿,硫酸盐的放射的气候效果从各种各样的方法由于重要影响显示出大不确定性。
1 INTRODUCTION Of three main methods for studying the radiative forcing of anthropogenic sulfate and climatic response on the regional scale, the first is, with given rates for transforming SO2 to sulfate, converting actually released SO2 into sulfate and acquiring the distribution of sulfate by computing transfer equations in the climate model. The second is obtaining the sulfate distribution through chemical reaction and transfer of matters in regional climate models online coupled with an atmospheric chemistry model that includes full chemical reactions for sulfides. The third is to put sulfate distribution data from GCM and its coupled atmospheric chemistry model to regional climate model, which is so called off-line coupled method. As shown in comparisons between the online and offline modeling on the regional scale, the radiative climate effect of sulfate shows large uncertainty due to significant influence from various methods.
