本文从云在气候模式中的代表性出发，评述了云对辐射场的影响。预计在不久的将来，这些模型将包括冷凝水作为额外的预测变量。我们研究如何简单的参数化的基础上的液态水含量可以逼真地模拟辐射场。我们专注于扩展的低层云，同时辐射和微物理测量的许多结果。特别注意的是云层中的短波吸收，因为理论计算的吸收系数一般比观测到的弱。破碎场的问题是接近的实际云量和等效云量之间的关系，给出了相同的辐照度，但使用平面平行的形式主义。
The influence of clouds on the radiation field is reviewed from the point of view of their representation in climate models. Such models are expected to include, in the very near future, condensed water as an additional prognostic variable. We examine how simple parameterizations based on the liquid water content can realistically simulate the radiation field. We focus on the extended low-level clouds for which numerous results of simultaneous radiation and microphysics measurements are available. Particular attention is given to the shortwave absorption in cloud layers because theoretically calculated absorptances are generally weaker than those observed. The problem of the broken field is approached in terms of a relationship between the actual cloud cover and the equivalent cloud cover which gives the same irradiances but using the plane-parallel formalism.
