The Madden-Julian Oscillation is the major contributor to rainfall in tropical regions and influences the climate in Europe regularly. Unlike Hurricanes and El Niño, the MJO is still not well understood. In an effort to understand the mechanisms of the MJO, I will describe a reduced order model of the MJO. This model is built starting from rotating hydrostatic Boussinesq fluid equations for the atmosphere. These equations are simplified through linearizations and projects which aim to capture large scale phenomena typical of the MJO. I will explain these approximations in detail. Then these equations are coupled to moisture in a simple way to give a linear PDE model of the MJO.
