Abstract: The usual assumption that vertically propagating internal gravity waves will cease growing with height once their amplitudes are such as to permit convective instability anywhere within the wave is reexamined. Two factors ...

Abstract: Recollections of the discovery of the quasi-biennial oscillation (QBO)of the equatorial stratosphere, and of the development of our present theoretical understanding of this phenomenon are presented.

Abstract: The classic Eady problem is modified to include ? ? 0, but with the basic distributions of temperature and zonal flow adjusted to preserve zero meridional gradients of basic-state potential vorticity in the fluid interior. ...

Abstract: The author reexamines the Charney?Drazin problem with special attention to the concentration of potential vorticity gradient in the neighborhood of the tropopause. It is found that the degree of concentration has a profound ...

Abstract: The response of the mesosphere to slow fluctuations in ultraviolet and visible radiation intensity is investigated using the simplified models for photochemistry and radiative transfer developed by Lindzen and Goody (1965). ...

Abstract: Laplace's tidal equation for diurnal tides of longitudinal number one is investigated. It is found that in addition to the previously found solutions (Hough Functions) corresponding to positive equivalent, depths there are ...

Abstract: The models developed in Part I for radiative transfer and ozone photochemistry in the mesosphere are incorporated into a two-level model for baroclinic flow, and the effect of radiative and photochemical processes on the ...
