Popis:	This study evaluates the performance of the Grid-point Atmospheric Model of IAP LASG, version 3 (GAMIL3), in simulating the Madden–Julian Oscillation (MJO), based on the CMIP6 (phase 6 of the Coupled Model Intercomparison Project) AMIP (Atmospheric Model Intercomparison Project) simulation. Results show that GAMIL3 reasonably captures the main features of the MJO, such as the eastward-propagating signal in the MJO frequency band, the symmetric and asymmetric structures of the MJO, several convectively coupled equatorial waves, and the MJO life cycle. However, GAMIL3 underestimates the MJO amplitude, especially for outgoing longwave radiation, as do most CMIP5 models, and simulates slow eastward propagation.
