The wind is also represented by a simple arrow. The winds in the atmosphere represent a flow of the atmospheric gases in a manner analogous to the flow of water in a river or to currents in the oceans, or even the flow of lava from a volcano . All have similar mathematical representation. A wealth of data can be found on the Earth Observing System Educator's page . For example, winds across the ocean causes waves to form, as seen here .
Students can investigate the correlation between the wind strengths and wave heights.
We have not used one of the most familiar weather phenomena in our mathematics exercises - clouds . A typical weather map symbolizes the percentage of cloud cover . And students can be asked to estimate this daily. They can download satellite images or measure this for the entire earth using NASA data . We have also not mentioned the amount of moisture in the air and how it is measured .
