摘要
利用建立的大气气溶胶辐射强迫模式,对我国历年大气气溶胶(TSP和硫酸盐气溶胶)引起的直接辐射强迫进行了计算,并给出其全国分布。得到了一些有意义的结果:我国大气气溶胶引起的辐射强迫与我国能源,特别是燃煤的消耗量密切相关,随着消耗量的增加,大气气溶胶(TSP和硫酸盐气溶胶粒子)引起的辐射强迫也增加;指出在利用辐射模式讨论大气气溶胶引起的直接辐射强迫时,不能忽视扬尘和沙尘的作用;我国由于大气气溶胶引起的直接辐射强迫主要集中在工业比较发达的城市或地区,四川盆地由于其特殊的地理位置和气候条件,在该地区因大气气溶胶产生的辐射强迫始终比较大。
The direct radiation forcing (RF) caused by atmospheric aerosol (TSP and sulfate aerosol) over the years was calculated through using the built RF model of atmospheric aerosol,and the geographic distribution was also got.The RF had close relation with the energy consumption in China,especially with her coal consumption.With the increase of coal consumption,the RF also increased.It was pointed out that fine sand and raise dust can not be ignored when discussing the RF by using RF models.The high values of RF in China were mainly located in those industry-developed regions and cities.The RF value in Sichuan Basin was larger all the time due to its special geographic and climate conditions.
