3. What is wind and how is it measured?
- NOTES
Wind is moving air.
Weather tools measure two properties of
wind - direction and speed.
4. Measuring Wind - NOTES
A weather vane spins freely in the wind and
points in the direction from which the wind is
blowing.
If a wind vane points east, the wind is blowing
from the east.
5. Measuring Wind - NOTES
An anemometer measures wind speed - how
fast the wind is blowing.
* This tool has several arms that stick out from a central rod. There is a
cup at the end of each arm. Wind blows into the cups and spins the
anemometer. The anemometer counts how many times it spins in a
given period of time. The faster the wind is blowing, the faster the
anemometer spins.
6. How is wind produced?
Differences in air temperatures and when air
moves from an area of high pressure to an
area of low pressure.
Storms that contain high winds are:
Blizzards, Tornadoes, and Hurricanes
