1. II. Local Winds in Global Context

    Students measure their local winds and then compare their findings to readings of surface winds in the Global Winds map.

    You know when it is a windy day, but just HOW WINDY is it? How do people measure the energy of local surface winds and compare them with winds in other places? What can affect the speed and direction of your local winds?  

    In this activity you can measure local winds with an anemometer. If you don't have one, you can release a balloon and, with the help of teammates, calculate the winds' speed by measuring the distance the balloon travels.  Then, knowing your local wind speed, you can compare it with the average surface winds over your area as displayed in the Global Winds map and consider differences you find.

    This activity builds on learning in the earlier activity, Exploring a Map of Global Winds.
