摘要
在实现计算T106L19模式大气参考状态的基础上,给出了两套有限区域模式大气参考状态,并对其数理特征进行了研究。讨论了可供计算的大气参考状态模式和实现了具体的模式大气参考状态。结果表明,有限区域大气参考状态其空气熵比较符合数学Γ概率密度函数分布,且其低层总存在一个逆温层,但都随季节及大气环流本身有着规律变化。
Two set of scientific data about the atmospheric reference state of the T106L19 model in a limited area (15°～60°N, 70°～140°E) are given, the one is in winter and the other is in summer, and some physical features of them are studied.The results show that their air entropies roughly respectively accord with a mathematical probability density function of the Γ-distribution, and there always is a stable inversion layer in their low level. But they will be changing regularly with the seasons and the atmosphere general circulation.
