6-10 How is wind measured?
SWBAT: Explain how weather instruments are used to describe wind.
wind vane - instrument that indicates wind direction
anemometer - instrument that measures wind speed
• A wind is named for the direction from which it comes; a wind from the north is called a north wind.
• Anemometers are often made of cups turned on their sides and attached to rods; the faster and stronger the wind, the faster the anemometer turns.
• Weather balloons are used to measure wind speed and direction high in the atmosphere.
