Stratospheric sudden coolings and the role of nonlinear wave interactions in preconditioning the circumpolar flow.
Journal of the Atmospheric Sciences 40:4 (1983) 909-928
Abstract:
The mechanisms responsible for the transition of the circumpolar flow from its normal midwinter state to this preconditioned state are investigated through a combination of observational numerical and theoretical studies. For the 1978-79 winter, this transition occurred during the substantial wavenumber-1 minor warming of January 1979, and the characteristic structure associated with the preconditioned mean zonal flow was established four days after the peak of this warming, during a period of intense high latitude acceleration.-from AuthorsBREAKING PLANETARY-WAVES IN THE STRATOSPHERE

Generalization of Cowling's Theorem
Geophysical & Astrophysical Fluid Dynamics 19:3-4 (1982) 301-309
Abstract:
An extension of Cowling's neutral point argument shows that no axisymmetric poloidal magnetic field can be maintained by self-exciting dynamo action in an electrically-conducting fluid against the dissipative effects of Ohmic heating. This generalizes previous results to cases where the magnetic field can be non-steady, the fluid compressible and the (scalar) coefficients of magnetic permeability and electrical conductivity dependent on position and time. © Gordon and Breach Science Publishers Inc., 1982PROPERTIES OF THE ELIASSEN-PALM FLUX FOR PLANETARY SCALE MOTIONS
