This electronic version of the 2nd Edition of the Glossary of Meteorology is meant to be a "living document" to be periodically updated as terms in our field evolve. To that end the AMS has established a "Chief Editor" for the Glossary who is responsible for updating/revising existing terms and adding new terms. Readers who would like to suggest changes to existing terms or propose definitions to the new terms are encouraged to submit their ideas to the Editor using the links at the left side of this page.
