The weighted essentially non-oscillatory (WENO) scheme is applied to a cloud-resolving model and is used for the cloud edge problem. Validity is tested using three idealized experiments and the results are compared with those of recent flux-corrected transport (FCT) schemes. In all three experiments, the WENO scheme simulates the energy properties of cloud edges better than the FCT schemes do. Because the WENO scheme can capture cloud edge more sharply, the buoyancy of the cloud edge is simulated without numerical diffusion. The increased buoyancy also causes enhancement of the convection cycle in deep convection through the cold pool, which is formed below the convective cell. This fact indicates that underestimations of convection strengths can be avoided using the WENO scheme.
