Weather Terms




          In this section you'll find many weather terms and their definitions. All of these weather terms are defined in as easy-to-understand terms as possible. Within each definition, if there is another word that has a meteorological definition, you can click-on it for its definition, as well. The weather terms are broken-up into alphabetical order by their first letter. These definitions come from valid meteorological sources. I invite you to see the bottom of this page for all the information sources I used to compile this list of definitions. If you have a weather term that is not listed on this site and you want to know what it means, e-mail the Webmaster for help.
