Utah’s Weather Guide, by Dan Pope and Clayton Brough (1997 News4Utah)
Background For Teachers:
Wind is one of the elements of weather. It is the movement of air that can be felt against our faces and bodies. We can see the effect of wind by the movement of objects. The direction, temperature, and speed of wind can help us predict changes in the weather.
Wind is the result of pressure differences in the atmosphere. This is why the weather people on TV care so much about high and low pressure systems.
A wind vane is an instrument that tells the direction the wind is moving.
Along with wind direction, meteorologists measure wind speed. Wind speed is a measure of how fast the air is moving. It is measured using an instrument called an anemometer. As the spinning cups of an anemometer turn, the speed of the wind is determined. Knowing wind speed and air pressure helps meteorologists forecast when an approaching storm will arrive or how long the weather in an area will remain.
Intended Learning Outcomes:
Invitation to Learn
Your anemometer is ready to use. Your anemometer is useful because it rotates with the wind. Try taking it somewhere that is windy so you can watch it spin. A fan can be used indoors if it is not windy enough outside to see if it works. Count how many revolutions it makes in one minute. Record your observations in your science journal. Include a description of how an anemometer works and is used by weather forecasters.
