Bulk and structural convergence at convection‐resolving scales in real‐case simulations of summertime moist convection over land

Convection‐resolving models (CRMs) are established as a solid framework to simulate moist convection in both numerical weather prediction and regional‐scale climate projections. However, capturing the different scales of the governing processes is challenging. Previous studies have shown that the size and properties of individual clouds and updraughts do not converge until horizontal grid spacings (Δx) of O (100 m). We refer to this as structural convergence. On the other hand, a few recent studies have demonstrated that domain‐averaged and integrated tendencies related to a large ensemble of convective cells converge at the kilometre scale. We refer to this as bulk convergence.
