Then you may be interested in a program developed by a group called "Plan!tnow" intended to help young people learn about meteorology and disaster preparedness. 

Part of the program is an online game involving the "Owlie Skywarn" character that is aimed at kindergarten through 8th grade students to help them be prepared for severe weather, and to act as ambassadors to others in their communities in understanding and coping with the impacts of adverse weather.

Parts of the program, which is in cooperation with the National Oceanic and Atmospheric Administration, the National Weather Service, the American Meteorological Society, and the National Education Association, tie in with educational goals in science, math, statistics and visualization, and kids who complete the game receive a certificate acknowledging their status as a "Young Meteorologist." 

There are also reading and online resource suggestions, and information about meteorology and atmospheric science as a potential career.

I've included a link here to the main site for the Young Meteorologist project, which goes to a screen where the game can be started. There is a "Learn More" button on that page as well, where you can find more background information about the goals of the program and how it is organized and administered.
