About

The single-baroclinic mode Neelin-Zeng Quasi-Equilibrium Tropical Circulation Model (QTCM1) is a primitive equation-based intermediate-level atmospheric model that focuses on simulating the tropical atmosphere. The qtcm package is an implementation of the Neelin-Zeng QTCM1 in a Python object-oriented environment using the f2py Fortran wrapping tool. The result is a modeling package where order and choice of subroutine execution can be altered at runtime, model analysis and visualization can also be integrated with model execution at runtime, while retaining the computationally light footprint of the original intermediate-level model.
