平流层气溶胶的辐射强迫及其气候响应的水平二维分析

Horizontal Two-Dimensional Distribution of Radiative Forcing and Climate Effect due to Stratospheric Aerosol

利用比较先进的辐射模式计算了平流层气溶胶的辐射强迫，并对之进行了参数化。结果发现平流层气溶胶的辐射强迫的水平分布不仅与其本身的水平变化有关，而且与下垫面的反照率有很大的关系。利用近期开发的二维能量平衡模式模拟了皮纳图博火山气溶胶对地面平衡温度的影响，结果表明：皮纳图博火山至喷发后１年半左右降温达最大，至喷发后第５年降温已很小。

The radiative forcing of stratospheric aerosol are calculated and parameterized in this paper It is found that the radiative forcing of this kind aerosol is not only related to its horizontal variation, but also to the surface albedo Furthermore, we have simulated the surface equilibrium temperature change induced by the Pinatubo volcanic aerosols using the two-dimensional energy balance model developed recently The results show that the surface temperature had the greatest decrease in late 1992 due to the Pinatubo aerosols, but the perturbation became very small in mid 1996
