抽象的。高级甚高分辨率辐射计（AVHRR）气溶胶光学厚度与国际卫星云气候学项目（ISCCP）月云量数据之间的长期和大尺度相关性表明，云量与气溶胶之间存在显著的区域尺度关系，与气溶胶-云相互作用一致。气溶胶和云量之间的正相关关系与北大西洋和太平洋风暴路径中的北美和亚洲气溶胶以及热带北大西洋的矿物气溶胶有关。在北非和印度尼西亚的生物质燃烧区附近以及北非主要矿物气溶胶源以南地区，可以看到负相关性。这些结果表明，有气溶胶和云的观测，可以使用大气环流模式，以验证云的直接和间接辐射强迫的正确强迫机制之间的关系。
Abstract. Long-term and large-scale correlations between Advanced Very High-Resolution Radiometer (AVHRR) aerosol optical depth and International Satellite Cloud Climatology Project (ISCCP) monthly cloud amount data show significant regional scale relationships between cloud amount and aerosols, consistent with aerosol-cloud interactions. Positive correlations between aerosols and cloud amount are associated with North American and Asian aerosols in the North Atlantic and Pacific storm tracks, and mineral aerosols in the tropical North Atlantic. Negative correlations are seen near biomass burning regions of North Africa and Indonesia, as well as south of the main mineral aerosol source of North Africa. These results suggest that there are relationships between aerosols and clouds in the observations that can be used by general circulation models to verify the correct forcing mechanisms for both direct and indirect radiative forcing by clouds.
