% Attempted hack to create BibTeX `jas' style for BibTeX version 0.99c
% Journal of Atmospheric Science, Journal of Applied Meteorology
% Monthly Weather Review
% by Mike Moran, Dept. of Atmospheric Science, Colorado State University
% based on `newapa' style file.  Changes are documented.  March 9, 1990
% Submitted 20-JUL-1993 by Piotr J. Flatau <pflatau@macao.ucsd.edu>
% e-mail for Mike Moran: <mmoran@cid.aes.doe.ca>
% ========================================================================
%
% BibTeX `newapa' style file for BibTeX version 0.99c, LaTeX version 2.09
% Place it in a file called newapa.bst in the BibTeX search path.  
%(Placing it in the same directory as the LaTeX document should also work.)
% Support for named citations is provided by named.sty

% This version was made by modifying the master file made by
% Oren Patashnik (PATASHNIK@SCORE.STANFORD.EDU), and the 'named' BibTeX
% style of Peter F. Patel-Schneider.

% This restriction helps ensure that all standard styles are identical.

% There are undoubtably bugs in this style.  If you make bug fixes,
% improvements, etc.  please let me know.  My e-mail address is:
%	spencer@heinlein.cgrg.ohio.state.edu
%
%   Citation format: (author-last-name, year)
%		     (author-last-name and author-last-name, year)
%		     (author-last-name {\em et al.}, year)
%                    (author-last-name)
%		     (author-last-name and author-last-name)
%		     (author-last-name {\em et al.})
%		     (year)
%
%   Reference list ordering: alphabetical by author or whatever passes
%	for author in the absence of one.
%
% This BibTeX style has support for abbreviated author lists and for
%	year-only citations.  This is done by having the citations
%	actually look like
%
%	\citeauthoryear{full-author-info}{abbrev-author-info}{year}
%
% The LaTeX style has to have the following (or similar)
%
%     \let\@internalcite\cite
%     \def\fullcite{\def\citeauthoryear##1##2##3{##1, ##3}\@internalcite}
%     \def\fullciteA{\def\citeauthoryear##1##2##3{##1}\@internalcite}
%     \def\shortcite{\def\citeauthoryear##1##2##3{##2, ##3}\@internalcite}
%     \def\shortciteA{\def\citeauthoryear##1##2##3{##2}\@internalcite}
%     \def\citeyear{\def\citeauthoryear##1##2##3{##3}\@internalcite}
