Meteorologists study weather daily and report forecasts using tools like thermometers, anemometers, wind vanes, hydrometers, barometers, and rain gauges. These instruments measure temperature, wind speed and direction, humidity, air pressure, and precipitation. Understanding weather is important for planning daily activities and meteorologist reports help people and families make decisions based on expected conditions.

8. Hydrometer
Weather instrument which measures
how much water vapor, humidity,
(evaporated water) is in the air.
Humidity is the
weather term which
describes the water
vapor in the air. The
higher the humidity
the higher the amount
of water vapor found
in the air.

9. Barometer
Weather instrument which measures
the amount of air pressure in a given
area. The higher the number the
higher the air pressure.
Measured in
millibars

10. Rain Gauge
Weather instrument which measures
the amount of rain or precipitation
that falls to the ground in a given
area.
