Preface

This manual describes the single baroclinic mode version of the Neelin-Zeng Quasi-Equilibrium Tropical Circulation Model (QTCM1), developed at the Department of Atmospheric Sciences at the University of California, Los Angeles (UCLA). Primary development of the QTCM1 was done by J. David Neelin and Ning Zeng. The original driver was written by William Weibel. Alistair Adcroft provided the direct Poisson solver used in the QTCM1. Chia Chou developed a cloud/radiation package used in the model. Hui Su and Ning Zeng wrote the slab mixed-layer ocean module. Bjorn Stevens led the development of the atmospheric boundary layer (ABL). Matthias Munnich implemented the ABL and converted the code to Fortran 90. This manual was written by Johnny Lin, Ning Zeng, David Neelin, Chia Chou, Hui Su and Matthias Munnich. Contributions to the documentation analysis and testing were also made by Katrina Hales and Joyce Meyerson.

This model and its documentation is, by necessity, offered to the community on an ``as-is'' basis, with no warranties or guarantees given or implied. However, we earnestly desire comments and suggestions to help improve both the model and the manual. Users are particularly requested to please notify us of any bugs they find in the model. The QTCM1 development team can be reached in care of:
