TY  - JOUR
AB  - A promising development of the last decade in the numerical modelling of geophysical fluids has been the compatible finiteelement framework. Indeed, this will form the basis for the nextgeneration dynamical core of the Met Office. For this framework to be useful for numerical weather prediction models, it must be able to handle descriptions of unresolved and diabatic processes. These processes offer a challenging test for any numerical discretisation, and have not yet been described within the compatible finiteelement framework. The main contribution of this article is to extend a discretisation using this new framework to include moist thermodynamics. Our results demonstrate that discretisations within the compatible finiteelement framework can be robust enough also to describe moist atmospheric processes.We describe our discretisation strategy, including treatment of moist processes, and present two configurations of the model using different sets of function spaces with different degrees of finite element. The performance of the model is demonstrated through several test cases. Two of these test cases are new cloudyatmosphere variants of existing test cases: inertia–gravity waves in a twodimensional vertical slice and a threedimensional rising thermal.
