摘要
Results from global simulations using a nonhydrostatic icosahedral-grid AGCM with cloud-resolving resolutions on an aqua planet are discussed. Results depend on the resolution. Simulations with grid intervals of 7 km and 3.5 km include many realistic features in the tropics: hierarchical cloud structures, a Madden-Julian Oscillation (MJO)-like intraseasonal oscillation, and diurnal precipitation cycles. Global cloud-resolving simulations show promise for future climate research. Such models avoid the liabilities associated with cumulus parameterization.
