Local Research, Studies, and Event Reviews

When we aren't making forecasts, issuing severe weather warnings, and going out into the community to increase weather awareness, our staff is perpetually working to improve the way we do things. This page offers a glance into some of the research that we are incorporating into daily operations and reviews of past weather events. These notes, papers, abstracts, articles, and technical memorandums are organized by topic. (If there are multiple authors not all from NWS Huntsville, NWS Huntsville authors are bolded.)

Note: Some files are in PDF format (click here to download a free PDF reader) and are several megabytes in size.
