Madden-Julian Oscillations (MJO) in six integrations using an AGCM with different cumulus parameterization schemes and resolutions are examined to investigate their impacts on the MJO simulation. Results suggest that the MJO simulation can be affected by both resolution and cumulus parameterization, though the latter, which determines the fundamental ability of the AGCM in simulating the MJO and the characteristics of the simulated MJO, is more crucial than the former.

1 INTRODUCTION The tropical intraseasonal oscillation or the Madden-Julian Oscillation (MJO) is a dominant mode of variability in the tropical atmosphere [1, 2]. At present, performances of the Atmosphere General Circulation Models (AGCM) in simulating th
