This paper provides a brief review and discussion of the recent main progress in the development of cloud-resolving model simulation. The dynamic and thermodynamic studies linked with convection development and precipitation process have contributed effective solution to the numerical models for estimation of surface rainfall budget. Research on Cloud Resolving modeling has gone through several developmental phases since 1980s and has claimed remarkable success recently despite several challenges yet on the way to perfection. A significant improvement was seen after the introduction of new cloud ratio (IWP/LWP) to derive tendency equation. However, the introduction of three vorticity vectors brought revolutionary changes in analytic process of 2D and 3D cloud-resolving model simulation data. They have several added advantages over PV/H in terms of understanding the causes for development of cloud clusters and super cloud clusters, differentiation of secondary circulation from dominant horizontal one. Non-conservative nature of vorticity vectors has provided the convenient pathway to their wider use in understanding meso-scale convective precipitation mechanism. The progress in modeling the cloud resolving process has been discussed in topical manner rather than following the chronological order.
