How do we measure the weather? Weather Tools How do we measure the weather?

MEASURING AIR PRESSURE Air pressure is the pressing by the air, or the strength of the air A barometer measures the air pressure Low air pressure means stormy or bad weather High air pressure means sunny and good weather

BAROMETER

MEASURING TEMPERATURE Temperature is the measure of how hot or cold something is Temperature is measured with a THERMOMETER

THERMOMETER A thermometer measures temperature in Degrees Celsius and Degrees Fahrenheit

MEASURING PRECIPITATION Precipitation is any kind of water that falls from the sky: rain, snow, sleet or hail Precipitation is measured with a RAIN GAUGE OR SNOWBOARD

RAIN GAUGE

SNOWBOARD Like long rulers that people stick into the snow to see how high it is.

MEASURING WIND Wind is the movement of air. Wind is measured with a WEATHER VANE and a ANEMOMETER

WEATHER VANE Shows Wind Direction

ANEMOMETER Measures Wind Speed Watch the red cup. Count how many times the red one goes around in 1 min. Divide this number by 10. Your answer is the MPH of wind.

WIND SPEED Wind speed can also be estimated with a Wind Scale that shows the movements of objects around you.

This is one example of a wind scale.

HOMEWORK: MAKE YOUR OWN WIND SCALE IN THE BOXES PROVIDED SHOW THE BIGGEST OBJECT THAT COULD BLOW GIVEN A CERTAIN SPEED OF WIND.
