AI中文摘要:
地球大气温度源于气候模型必须考虑的复杂现象,其中重要模块为辐射,其有三个来源:地球与空气发射的红外辐射,以及太阳发出的可见光。后者来自天空中几乎点状的光源,在边界条件中产生狄拉克奇点,即准直光。遵循Siewert和Maiorino(1980)的方法,我们提出一种极快速的数值实现方案来处理该奇点。
英文摘要:
Atmospheric temperature on Earth results from complex phenomena that climate models must account for. One important module is radiation, which has three sources: infrared radiation emitted by the Earth and the air, and visible light from the Sun. The latter arrives from an almost point-like source in the sky, producing a Dirac singularity in the boundary conditions known as collimated light. Following Siewert and Maiorino (1980), we propose a very fast numerical implementation to handle the singularity.
