An idealized model is presented that can represent the main features of the tropical atmosphere. The model uses a truncated vertical structure with only two vertical modes. It is numerically integrated to a steady state that represents the climatology of the tropical atmosphere. The numerical model is non-oscillatory, so discontinuous flows can be represented well, and the numerical model can represent a balanced state of the atmosphere to machine precision.
