Data for: Bulk microphysics schemes may perform better with a unified cloud-rain category

Bulk microphysics schemes continue to face challenges due in part to the necessary simplification of hydrometeor properties and processes that are inherent to any parameterization. In all operational bulk schemes, one such simplification is the division of liquid water into two subcategories (cloud and rain) when predicting the evolution of warm clouds. It was previously found that biases in collisional growth in a bulk scheme with these separate liquid water categories can be mitigated with a unified liquid water category in which cloud and rain are contained within the same category. In this study, we examine the effect of artificially separating the liquid water category on other microphysical processes and in more realistic settings. Both our idealized 1D and 3D results show that a unified category bulk scheme is fundamentally better at predicting the timing and intensity of rain from warm-phase cumulus clouds compared to a traditional (separate) category bulk scheme. This is becaus..., This dataset is generated using KiD_AMP and the Regional Atmospheric Modeling System (RAMS). The simulation output is further summarized and visualized using MATLAB. , , # Data for: Bulk microphysics schemes may perform better with a unified cloud-rain category
