"The Use of Assimilated Stratospheric Data in Constituent Transport
Calculations," R.B. Rood (NASA/GSFC, Code 616, Greenbelt MD 20771), D.J.
Allen et al., J. Atmos. Sci., 46(5), 687-701, Mar. 1, 1989.
Reports the first known calculations to use data from an assimilation to
calculate constituent transport in the stratosphere. Among the results, accurate
calculations of high-latitude time variance of HNO3 were shown. Studies suggest
data from an assimilation process have great potential for the study of
stratospheric dynamics, constituent transport and chemistry.
"On the Antarctic Ozone Hole," M.E. McIntyre (Dept. Appl. Math.
& Theor. Phys., Silver St., Cambridge, CB3 9EW, UK), J. Atmos. Terr.
Phys., 51(1), 29-43, 1989.
In this review, presented at the Middle Atmosphere Dynamics Symposium of the
1987 IUGG Assembly in Vancouver, the author stresses the need for
high-resolution numerical modeling results along with observations and dynamical
theory to study the ozone hole. Suggests the need for sharp distinctions to be
made, for example, between September and October behavior, between behavior near
50 mb and near 100 mb, and between soundings taken well inside, near the edge
of, and outside the polar vortex.
"Summertime Stratospheric Wind Measurements Above the South Pole,"
G.J. Byrne (Phys. Dept., Univ. Houston, Houston TX 77204), J.R. Benbrook et al.,
Presents mean wind flow and wave motions in the stratosphere at the South
Pole during the austral summer of 1985-1986, obtained by tracking a
high-altitude, zero-pressure balloon. It appears that the dominant component of
the total wind vector over the duration of the flight was air motion associated
with internal gravity waves. This implies that wave motions play a dominant role
in the transport of stratospheric constituents in regions where the mean winds
