In absence of forcing and dissipation, the atmosphere can be described
within the framework of Hamiltonian dynamics. We introduce the
parcel formulation for such a atmosphere, which forms the basis of our
Hamiltonian numerical method.
Although our climate is ultimately driven by (nonuniform) solar
heating, many aspects of the flow can be understood qualitatively from
forcing-free and frictionless dynamics. In this limit of zero forcing and
