    Global non, hydrostatic model, Icosahedral grid, Global cloud-resolving simulations

    Icosahedral grids for grid division levels of 3, 4, and 5 (from left to right) (horizontal mesh spacings of approximately 893, 446 and 223 km).

    Cloud distribution simulated by the NICAM 870 m grid spacing experiment.

    This article reviews the development of a global non-hydrostatic model, focusing on the pioneering research of the Non-hydrostatic Icosahedral Atmospheric Model (NICAM). Very high resolution global atmospheric circulation simulations with horizontal mesh spacing of approximately O (km) were conducted using recently developed supercomputers. These types of simulations were conducted with a specifically designed atmospheric global model based on a quasi-uniform grid mesh structure and a non-hydrostatic equation system. This review describes the development of each dynamical and physical component of NICAM, the assimilation strategy and its related models, and provides a scientific overview of NICAM studies conducted to date.
