1 The title must be shorter than 100 characters, both concise and informative Kim M. Cobb and Jean Lynch-Steiglitz (note: writer is first, collaborators listed as co-authors) Georgia Inst. of Technology, Atlanta, GA Abstract. The manuscript’s abstract is a concise summary of its contents, and must be 150 words or less. The necessary components include: a statement of the problem, a description of the approach, summary of main results, and the implications of the results. (NOTE: use only 12pt Times New Roman for your papers, double-spaced, except for references) Introduction The introduction should frame the scientific problem that the article addresses, and clearly state the purpose for the study. References must be cited as [Zhang et al, 1997; White and Cayan, 1998; Garreaud and Battisti, 1999] or simply [Zhang et al., 1997] for a single reference. The introduction should be no longer than 250 words. Methods The methods section should describe the approach and methods used to arrive at the results. This section should be no longer than 200 words. Results The results section contains a clear, objective presentation of the results of the study. This section should emphasize the results that are most important – too many details will confuse the reader and obscure your important points. This section should be no longer than 250 words. Discussion A good discussion section places the important results in a larger context for the reader. It typically involves several of the following: a comparison of the results with those from other studies, the creation of an interpretive framework for the results, and the discussion of any 2 important caveats and/or assumptions that are associated with the results or their interpretation. Most importantly, the discussion should end with a short concluding paragraph in which the main conclusions are summarized. The discussion section should be no longer than 400 words.

The figure captions should describe the figure for the reader in 1-2 sentences. [A note on figures]: Figures can either be included in the body of the text (using text boxes and/or tables), in which case Figure captions must be directly under the respective figure. More typically, figure captions are placed at the end of the text manuscript, and figures are appended to the back of the paper, each one clearly labeled ‘Figure 1’, ‘Figure 2’, etc.
