Sea-Breeze Dynamics and Convection Initiation: The Influence of Convective Parameterization in Weather and Climate Model Biases

摘要: AbstractThere are some long-established biases in atmospheric models that originate from the representation of tropical convection. Previously, it has been difficult to separate cause and effect because errors often result a number interacting biases. Recently, researchers have gained ability run multiyear global climate model simulations with grid spacings small enough switch convective parameterization off, which permits convection develop explicitly. There clear improvements initiation storms diurnal cycle rainfall convection-permitting simulations, enables new process-study approach bias identification. In this study, atmosphere-only without undertaken Met Office Unified Model analyzed over Maritime Continent region, where convergence sea-breeze circulations is key for initiation. The analysis s...
