An Idealized Model for the Climate of the Tropical Atmosphere

Samuel Stechmann, New York University

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.
