Observation of mesospheric air inside the arctic stratospheric polar vortex in early 2003 [PDF]

open access: yes, 2005
During several balloon flights inside the Arctic polar vortex in early 2003, unusual trace gas distributions were observed, which indicate a strong influence of mesospheric air in the stratosphere.

A Mechanism Involving Solar Ultraviolet Variations for Modulating the Interannual Climatology of the Middle Atmosphere [PDF]

open access: yes, 1990
In years of low solar activity, free traveling wave modes in the upper stratosphere are dominated by atmospheric normal modes such as the 16-day wave. However, within a 4-year interval centered on the 1980 to 1981 solar maximum, cross-spectral analyses ...

Possible dynamical mechanisms for the Martian polar warming phenomenon [PDF]

open access: yes
The research performed under NASA contract NAGW-727 falls into three major categories, i.e., dynamical modeling of the Martian polar warming phenomenon, studies of dust and water transport associated with a Martian polar warming, and studies of the ...

Energetics of a sudden stratospheric warming simulated with a three-dimensional, spectral, quasi-geostrophic model [PDF]

open access: yes
The energetics of a three dimensional, quasi-geostrophic simulation of a sudden stratospheric warming which developed spontaneously during an annual cycle simulation are described.

Transport of Mars atmospheric water into high northern latitudes during a polar warming [PDF]

open access: yes
Several numerical experiments were conducted with a simplified tracer transport model in order to attempt to examine the poleward transport of Mars atmospheric water during a polar warming like that which occurred during the winter solstice dust storm of

Theoretical and experimental investigations of upper atmosphere dynamics [PDF]

open access: yes
A brief overview of the significant contributions made to the understanding of the dynamics of the Earth's upper atmosphere is presented, including the addition of winds and diffusion to the semi-empirical Global Reference Atmospheric Model developed for
