Welcome to the Hands-On, Minds-On Meterology Program Page!
Hands-On, Minds-On Meteorology is a collection of interactive concept models (programs) designed to help depict atmospheric principles graphically and teach valued lessons in meteorology. Many of these programs have guided instruction exercises to accompany them and even include graphing and journaling tools.

These programs require the latest free Java* Software for your desktop.
To install, click on the button at left, and follow the Get It Now link on that page.

*Java is a trademark or registered trademark of Sun Microsystems, Inc. in the United States and other countries.

A list of all the available Concept Mdels follows. Some are more polished than others. For help on using the tools, please read our documentation pages. There are pages for each program, as well as general information about the whole project. Enjoy!!
