Submissions may also contain Supplemental Material (if any; to be uploaded as a separate file)


Abstracts: 250 words. This conforms to ISO standards and the needs of abstracting services (MGA, etc.).

Expedited Contributions: Up to 2500 words (abstract, references, figure captions list, tables, and figures do not count toward the length limit). No more than a combined total of 6 tables and figures. No length waivers can be granted.  Note that due to improvements in AMS overall production time, new Expedited Contributions can no longer be submitted after 31 December 2017.  You can read more about this decision.

All other manuscript types: 7500 words or less not counting the abstract, figure caption list or references. If a submission exceeds the word limit the author must upload a cover letter with the manuscript presenting a justification for the length of the manuscript to request the Chief Editor’s approval of the overage.

Margins Margins must be approximately one inch (2.5cm).
Line Spacing All copy must be double spaced, including the references and list of figure captions. AMS defines double spacing as no more than three lines of text per inch (2.5 cm). 
Paragraph Breaks Paragraph breaks must be visually designated. Please either indent the first line of each new paragraph or insert an extra line space between the paragraphs (the extra line should leave at least 5/8 in. or 1.5 cm of white space).
Page, Line, and Section Numbering All submissions must include line numbering. Pages must be numbered sequentially. Please see Body Text (below) for more details about section numbering.
Font Black text. Sized 12 pt. font or larger.
Acronyms and Abbreviations See List of Acronyms and Abbreviations
AMS Style for Common Meteorological Terms See AMS Style for Common Meteorological Terms
Mathematical Formulas, Units, Time, Date See Mathematical Formulas, Units, and Time and Date
Tables All tables should have a double-spaced caption. If desired, the preferred way to highlight table information is to use bold or italic font styles. Tables cannot contain shaded cells, underlining, or colored fonts. Footnotes can be used if additional information must be indicated. See Tables (below) for more guidance.

Manuscript Components

Title Page

The manuscript title, name and affiliation of each author, any current or additional affiliations, and corresponding author email need to appear on the first page in the manuscript file. For more information regarding author lists, please see Your Author List.


A concise (≤ 250 words) abstract is required at the beginning of each article and, at the discretion of the chief editors, at the beginning of appropriate shorter contributions. Authors should summarize their conclusions and methods in the abstract. First-person construction (e.g., I/my/we/our) and reference citations are not permitted. 

Please note the abstract text in the manuscript must match exactly the abstract text entered in the abstract field of the upload system. If the abstract text entered in the abstract field of the upload system does not match the abstract in the manuscript then the submission will be returned to the author for correction.

Capsule (for BAMS only)

Include in the text of the manuscript (before or after the abstract) a short (20-30 words maximum) Capsule Summary of your Article. No capsule is required for Nowcast, In Box, or Meeting Summary manuscripts. The Capsule Summary will be placed underneath the title and authors of your article. The more detailed Abstract will be placed on a separate page in the front of the magazine.

Complete list of BAMS submission types and article components 

Body Text

The text should be divided into sections, each with a separate heading and numbered consecutively. The section/subsection headings should be typed on a separate line [e.g., 1. Introduction, a. Data, 1) RADIOSONDE, and (i) Experiment 1]. Sections in BAMS need not be numbered. See above for more information on Formatting.


The AMS requires that all topically relevant funding sources, including recipients and grant numbers, as well as conflicts of interest, are fully disclosed in the Acknowledgments of all submissions. Please omit the word “number” from grant or contract information.


Auxiliary analyses or tables whose details are subordinate to the main theme of the paper should normally appear in an appendix. Please note that any tables or figures intended to appear in an appendix should not be embedded and must be located after the references with the other manuscript tables and figures. Each appendix must have a title. Example:
Use of Model Data

References and Citations

References should be arranged alphabetically without numbering. The in-text citation should consist of the author's name and year of publication, [e.g., “according to Rossby (1945),” or “as shown by an earlier study (Rossby 1945)”]. When there are two or more papers by the same author in the same year, the distinguishing suffix (a, b, etc.) should be added.

Sidebars (for BAMS only)

A short story within a larger story, sidebars present content that is relatively self-contained. It is usually somewhat incidental to the main article—not critical for the generalist reader to understand the thread of the article. Historical background, explanatory detail, or other information of interest, for example, are common sidebar features. Not to exceed 500 words, sidebars should be placed in the manuscript after the References but before the Tables.


The tables cannot be embedded in the body of the manuscript. They should appear after the references and before the figures. Each table must be cited specifically in the text and in numerical order, and each table must have a caption. See above for formatting tables.

Figure Caption List

Each figure must have an adequate caption, and the full caption text must appear beneath the figure in the built PDF. In addition, a list of figure captions must be included in the manuscript at the revision stage. The list should appear after the references and before the figures are displayed individually.


  • All figures should display once at the end of the system-built PDF with the full caption text. Figures cannot be embedded in the body of the manuscript.
  • Please note all figure source files for production are required at the revision stage. The print-quality original figure files must be uploaded in one of the accepted formats.
  • Authors should submit one complete figure per figure file. Multiple-panel figures that will appear on a single page should be combined into a single file whenever possible. 
  • Figures should be prepared according to the guidelines specified on Figure Information for Authors. Please be sure to consider accessibility needs when selecting color palettes as described in the Color Mode section.
  • Technical editors may resize the figures for layout purposes.
  • It is the policy of the AMS Publications Commission that the use of color in figures during peer review must match the color or black and white format that will appear in print.
  • Note that BAMS encourages the use of color by authors and does not levy additional charges for color figures.

For additional information regarding which item type to select when uploading your figure source files, please refer to the list of item types.

Supplemental Material

Supplements should contain material that is typically not part of a standard journal article; this material should not be essential to the article itself, which must stand alone. Supplements should not be used as a vehicle to circumvent manuscript word limits or page charges. If accepted, this material will be published online only.

Note that as related material, article supplements are covered under the AMS Copyright Policy and as such the same conditions and reuse policies that apply to articles also apply to supplements.

Examples of material that may be appropriate for supplements:

  • Animations
  • Small datasets
  • Computer codes not available through data citation
  • Tables too large to be formatted properly on a printed journal page
  • Compilation of graphics that are not essential for understanding the article

Examples of material that are not appropriate for supplements:

  • Material that is suitable for inclusion in an appendix (descriptions of datasets, models, or techniques, etc.)
  • Additional figures and/or text that would be considered more appropriate as part of the article itself

Journal Editors and, if requested, peer reviewers will evaluate electronic supplements using the same scientific standards as is used for the rest of the manuscript to determine if they are appropriate and truly supplemental. Unlike the article itself, supplementary material does not undergo copy and technical editing (except for BAMS). Supplements are linked to the article online when published and are assigned their own DOI number.

Editors will have the ultimate responsibility for determining whether the supplement is appropriate and acceptable.  Authors should provide a short justification to the editor that explains how the supplement will benefit the readers of the article, and why the material is not included in the article.  Supplements with excessive length will not be approved.

Supplemental material should not be included in the main manuscript file.  It should be in a separate file (designated with the item type "Supplemental Material" during the submission process).  Authors can choose to upload a single file, a zip file containing multiple files, or several separate files.
