英文摘要	This project examines physics/dynamics coupling, that is, exchange of meteorological profiles and tendencies between an atmospheric modelâs dynamical core and its various physics parameterizations. Most model physics parameterizations seek to represent processes that occur on scales smaller than the smallest scale resolved by the dynamical core. As a consequence a key conceptual aspect of parameterizations is an assumption about the subgrid variability of quantities such as temperature, humidity or vertical wind. Most existing parameterizations of processes such as turbulence, convection, cloud, and gravity wave drag make relatively ad hoc assumptions about this variability and are forced to introduce empirical parameters, i.e., âtuning knobsâ to obtain realistic simulations. These knobs make systematic dependences on model grid size difficult to quantify.
