Washington, D.C.
Washington, D.C., formally the District of Columbia and commonly referred to as Washington, "the District", or simply D.C., is the capital of the United States. On July 16, 1790, the United States Congress approved the creation of a permanent national capital as permitted by the U.S. Constitution....

, Bryan worked with a series of colleagues to develop numerical schemes for solving the equations of motion describing flow on a sphere. His work on these schemes led to the so-called "Bryan-Cox code" with which many early simulations were made, and which led to the Modular Ocean Model
Modular Ocean Model
The modular ocean model is a three-dimensional ocean circulation model designed primarily for studying the ocean climate system. The model is developed and supported primarily by researchers at the National Oceanic and Atmospheric Administration's Geophysical Fluid Dynamics Laboratory .- Overview...

 currently used by many numerical oceanographers and climate scientists.

In addition to his important contributions in developing numerical codes, Bryan was also involved in early efforts to apply them to understanding the global climate

 system. In 1967, he published, with Michael Cox, the first model of the 3-dimensional circulation of the ocean, forced by both winds and thermodynamic forcing. In 1969, a paper with Syukoro Manabe was the first to present integrations of a fully coupled atmosphere-ocean model, demonstrating the importance of ocean heat transport

 demonstrated the important role played by bottom topography in setting the structure of the global ocean circulation, and played a major role in suggesting links between changes in continental topography and climate, continuing a long-term interest in the role of oceanic heat transport in determining global climate.
