1. Go to an article, say http://journals.ametsoc.org/doi/abs/10.1175/MWR-D-16-0460.1
2. On the red bar, click on the download button (third icon from left).
3. This screen appears: http://journals.ametsoc.org/action/showCitFormats?doi=10.1175%2FMWR-D-16-0460.1
4. At the bottom, you can copy the text for the reference list, including the doi.
Steenburgh, W.J. and L.S. Campbell, 2017: The OWLeS IOP2b Lake-Effect Snowstorm: Shoreline Geometry and the Mesoscale Forcing of Precipitation. Mon. Wea. Rev., 145, 2421–2436, https://doi.org/10.1175/MWR-D-16-0460.1
5. Paste it into your Word file.
6. To get it in proper format for Word, unlink the title to a hot link (command-K on my Mac), decapitalize the nonproper nouns in the title, and change the URL to a proper doi: “doi: 10.1175/MWR-D-16-0460.1”.
Done.
