The principle tools that I use to understand the
atmosphere are numerical models of the atmospheric
circulation. Much of my research is done with global primitive
equations models. The primitive equations are a
simplification of the Navier-Stokes
equations of fluid motion, which are appropriate for the
large scale circulation of the Earth's atmosphere. These
models are also known as "dynamical cores," as they form
the core of a comprehensive atmospheric model.
This page describes some of the models we have running
here at NYU. They were developed by scientist at the
Dynamics Laboratory in Princeton.
