TOOLS
What are they?
What do they do?
THE MOST COMMON WEATHER
TOOLS ARE:
•Barometer
•Psychrometer
•Thermometer
•Rain Gauge
•Weather Vane
•Anemometer
BAROMETER
• Barometers are used to
measure air pressure.
• Measured in millibars (mb).
• Can predict good or bad
weather.
• High air pressure= good,
sunny weather!
PSYCHROMETER
• Measures humidity
(amount of water vapor) in
the air
• Measured in grams of
water per cubic meter of
air (g/m3)
• Temperature affects
humidity
THERMOMETER
• A thermometer is used to
measure temperature.
• Can be measured in
Fahrenheit or Celsius.
RAIN GAUGE
• A rain gauge is a
weather tool used to
collect rain.
• Using measurements on
the side of the rain
gauge, you can see how
many inches it rained.
• Measured in inches of
water.
WEATHER VANE
• By observing wind vanes,
we can know the direction
of the wind.
• Measured in directional
units: North, South, East,
West
• Knowing the direction of
the wind is an important
part in predicting the
weather.
ANEMOMETER
• An anemometer measures
wind speed
• Measured in miles per
hour (mph)
• How fast it spins
determines how fast the
wind is blowing
