Through watching several classic air pressure demonstrations, middle schoolers determine that high pressure areas move toward lower pressure areas, heated air causes a drop in pressure, and forces exist when pressures are unequal....

What causes wind? How does wind affect our weather? This website is neatly organized into topics about pressure, gradient force, Coriolis force, geostrophic wind, gradient wind, friction, boundary layer wind, and sea and land breezes....

Explains what a pressure gradient is and how it produces air movement.

Interactive media is used to explain the differences between high pressure and low pressure weather systems.

An introduction to the factors that affect the Arctic's weather and climate: latitude, land/sea distribution, solar radiation, air temperature, air pressure, winds, humidity, clouds, and precipitation.

Read about regional and local wind systems, including information on changes in atmospheric pressure, thermal energy in the atmosphere, sea and land breezes, mountain and valley breezes, and monsoon winds.

Describes the ways in which wind direction and barometric pressure can be used by the amateur weather forecaster to make predictions about the weather.

This site from the University of Oregon provides a great explanation of the Coriolis Effect and then gives several chart type examples to help the understanding of it.
