Convectively coupled equatorial waves (CCEWs) and the Madden-Julian Oscillation (MJO) are responsible for significant amount of tropical rainfall variability. However, simulating both CCEWs and the MJO realistically at once is still a challenge in comprehensive 3D models. In this study, I will present a 2D model that simulates equatorial dynamics in the x-z domain. The goal of this study is to simulate both CCEWs and the MJO realistically and to understand their basic mechanisms. This study has implications on improving convection parameterizations in 3D climate models.
