Along with the audio files to support the Lucidity papers (see lucidity-readme.txt) this anonymous ftp directory (transferred from an obsolete ftp server to our web server) contains selected recent preprints and reprints, mostly from the 1990s and mostly in the form of *.ps.Z (standard Unix-compressed postscript) files. These last can be viewed automatically by web browsers that call up ghostview or, on most Unix systems, viewed or printed by commands such as uncompress .ps then xdvi .ps or lpr .ps. Some files are of the more recent form *.ps.gz and are uncompressed by gunzip .ps The file polarcool.ps.Z (formerly fermi-review.tex) is a review paper written for a broad audience of atmospheric chemists, and other scientifically-minded non-specialists in fluid dynamics, who may be interested in gaining a quick impression of the most basic facts and ideas about global-scale atmospheric dynamics. Dynamical processes relevant to the ozone layer are emphasized. Included, for instance, is a careful discussion of the `polar cooling thought-experiment' (section 6, p.14), the basic difficulty with the concept of `eddy diffusivity' (section 10, pp.30,33ff.) --- on this, see also section 3, p.6, of challenge.ps.Z --- and the various incompatible uses of words like `source' and `sink' that are apt to cause confusion (section 11, p.36ff.). Some of the discussion of the global-scale circulation and stratosphere-troposphere is now superseded by the more recent review of Holton et al, Stratosphere-Troposphere Exchange (Reviews of Geophysics, 33(4), 403--439), supplemented by the files downwardcontrol* in this directory, and the rather rudimentary discussion of long-lived chemical tracers is superseded by more recent work by R. A. Plumb and his co-workers, on the "age spectrum" of air, etc., a line of thinking originating in the 1988 paper by Plumb and McConalogue in JGR 93, 15897. The files vision* are about my personal vision, or rather Optimist's Fantasy, of the future of weather forecasting and a few other things; see also "Lucidity and Science Part III" at http://www.atm.damtp.cam.ac.uk/people/mem/papers/LHCE/ The "walking lights" demonstration used in the Lucidity papers is also available from this ftp directory in several versions lucidity-walking-lights*.gif, etc (the same demonstration playing at different speeds, hopefully able to accommodate different computers and browsers). NOTE: the file lucidity-corrigendum.html contains an important correction to some statements in Lucidity Part III. The "tape recorder" papers came out in JGR in 1996 and 1998: Mote, P. W., Rosenlof, K. H., McIntyre, M. E., Carr, E. S., Gille, J. C., Holton, J. R., Kinnersley, J. S., Pumphrey, H. C., Russell III, J. M., Waters, J. W., 1996: An atmospheric tape recorder: the imprint of tropical tropopause temperatures on stratospheric water vapor. J. Geophys.\ Res., 101, 3989--4006. Mote, P. W., Dunkerton, T. J., McIntyre, M. E., Ray, E. A., Haynes, P. H., Russell, J. M. III, 1998: Vertical velocity, vertical diffusion, and dilution by midlatitude air in the tropical lower stratosphere. J. Geophys.\ Res., 103, 8651--8666.
