General circulation experiments with the primitive equations
TL;DR: In this article, an extended period numerical integration of a baroclinic primitive equation model has been made for the simulation and the study of the dynamics of the atmosphere's general circulation, and the solution corresponding to external gravitational propagation is filtered by requiring the vertically integrated divergence to vanish identically.

A proposed modification of the Germano subgrid‐scale closure method
TL;DR: In this paper, the subgrid-scale closure method developed by Germano et al. is modified by use of a least squares technique to minimize the difference between the closure assumption and the resolved stresses.
Eddies Stream, and Convergence Zones in Turbulent Flows
TL;DR: In this article, a set of objective criteria were found which describe regions in which the streamlines circulate, converge, or diverge, and form high streams of high velocity flow.
