This "kite science" site offers information on wind and the atmospheric conditions that cause it. From "Principles of Aeronautics."

A concise explanation of El Nino. Discusses global wind patterns and ocean temperatures. Offers interactive weather-related learning activities.

Imagine our weather if Earth were completely motionless, had a flat dry landscape and an un-tilted axis. This, of course, is not the case; if it were, the weather would be much different. The local weather that impacts our daily lives...

A great description of the global scale circulation and heat energy. Discusses a single-cell model, a three-cell model, jet streams and more.

In this illustrated essay from NOVA Online, explore the cyclical process of weather creation and the effects of El Nino on the global weather system.

This site provides a lesson plan in which groups of learners will each investigate a different type of weather map use for weather forecasting. Also includes discussion questions, extension ideas, and links to additional sites for more...

A video and a short multiple-choice quiz on the topic of weather and climate, and the difference between them.

The concept of jet streams is explained on this site. Read about why jet stream winds blow from west to east, what the polar jet and subtropical jet are, the role that the rotation of the Earth plays, etc.

Use remote sensing data and background information to look at regional and global consequences of El Nino. Try working with the 'situation' to test your understanding.

Students track barometric pressure, wind direction, temperature, and clouds. The class records daily readings in these for areas and attempt to formulate patterns to use in forecasting the weather based on these elements.

This site from the University of Illinois explains basic principles of weather radar, its development, and application to weather forcasting. Includes section on how wind patterns are shown using doppler radar.
