Abstract: Planetary-scale, stationary disturbances in the winter stratosphere are considered to be upward propagating internal Rossby waves forced from below. Numerical solutions to the linearized equation for wave propagation are ...

Abstract: me consists of some papers presented at the AMS Symposium held to honor the memory of the late Professor Michio Yanai as well as additional works inspired by his research. By the nature of this volume, many of the contributed ...

Abstract: The dynamics of the stratosphere sudden warming phenomenon is discussed in terms of the interaction of vertically propagating planetary waves with zonal winds. If global-scale disturbances are generated in the troposphere, ...

Abstract: The Eulerian-mean (usual zonal mean) and the Lagrangian-mean (an average in the zonal direction along a curved ?material line,? consisting of definite individual air particles) meridional circulations are investigated, ...
