A new radiation scheme has been developed for dynamic general-circulation modeling. An automatic determination of k-distribution parameters and a treatment of solar-terrestrial radiation interacting with gaseous and particulate matter are incorporated into the scheme by a technique that combines discrete ordinate and matrix operator methods. An accelerated scheme for cloud overlap is developed and tested. The resultant accuracy of the scheme is ?0.5 K/day to a 70-km height in clear sky better than that of the line-by-line calculation method.
已开发出一种用于动态大气环流建模的新辐射方案。通过结合离散坐标法和矩阵算子法的技术,该方案纳入了k分布参数的自动确定以及对与气态和颗粒物相互作用的日地辐射的处理。此外,还开发并测试了一种加速云重叠方案。在晴空条件下,该方案在70公里高度处的精度达到±0.5K/天,优于逐线计算方法。
