SO_2排放、硫酸盐气溶胶和气候变化

SULFUR DIOXIDE EMISSIONS, SULFATE AEROSOL AND CLIMATE CHANGE

工业ＳＯ２排放的增加使对流层大气中硫酸盐气溶胶浓度增大，硫酸盐气溶胶通过其直接和间接辐射强迫作用影响气候变化。有关的研究结果显示：硫酸盐气溶胶的冷却效应在一定程度上抵消了温室效应，北半球增暖趋势的减缓和日较差的减小可能与大气中人为硫酸盐气溶胶浓度的增加有关。

Anthropogenic emissions of sulfur dioxide from industrial activity are now known to be large enough to produce significant increases in sulfate aerosol abundances. The resulting increased particles in the atmosphere affect the climate change through the direct and indirect effects. Related research results show that cooling effects of sulfate aerosol compensate the greenhouse effect to certain extent due to increases in anthropogenic trace gases, which would lead to slower warming in Northern Hemisphere and lower diurnal temperature range.
