使用基于质量通量的方法，将热力学积云参数化问题重新表述为一个简单的大气模型，该模型是浅水方程的模拟。目的是研究几个参数化类别的初等表示的基本效果。特别是，进行了线性稳定性分析和单柱实验，以推断每个参数化在模拟热带对流大尺度组织或相干性方面的特征。
Using a mass‐flux based approach, the thermodynamic cumulus parametrization problem is reformulated in a simple atmospheric model, which is an analogue of the shallow‐water equations. The objective is to investigate basic effects of elementary representations of several parametrization categories. In particular, a linear stability analysis and a single‐column experiment are performed to infer the characteristics of each parametrization as regards its ability to simulate the large‐scale organization or coherence of tropical convection.
