Abstract
AbstractWe propose an integrated dynamics‐physics coupling framework for weather and climate‐scale models. Each physical parameterization would be advanced on its natural time scale, revise the thermodynamics to include moist effects, and finally integrated into the relevant components of the dynamical core. We show results using a cloud microphysics scheme integrated within the dynamical core of the Geophysical Fluid Dynamics Laboratory System for High‐resolution prediction on Earth‐to‐Local Domains weather model to demonstrate the promise of this concept. We call it the in‐line microphysics as it is in‐lined within the dynamical core. Statistics gathered from 1 year of weather forecasts show significantly better prediction skills when the model is upgraded to use the in‐line microphysics. However, we do find that some biases are degraded with the in‐line microphysics. The in‐line microphysics also shows larger‐amplitude and higher‐frequency variations in cloud structures within a tropical cyclone than the traditionally‐coupled microphysics. Finally, we discuss the prospects for further development of this integrated dynamics‐physics coupling.
