6-4.5

• Use appropriate instruments and tools to collect
  weather data (including wind speed, and
  direction, air temperature, humidity, and air
  pressure).

3
What Is Weather?

• Weather refers to the conditions of the
  atmosphere at a certain place and time.
• Climate deals with long-term conditions
  in the atmospherepatterns, averages, and
  extremes (most/maximum and least/ minimum).

4
We Cant See Air, So What Can We Measure?

• Temperature
• Pressure
• Wind direction and speed
• MoistureHumidity and Dew Point
• Cloudscoverage and type
• Precipitationtype and amount

5
The Most Common Weather Tools Are

• Thermometer
• Wind Vane
• Wind Sock
• Anemometer
• Barometer
• Rain Gauge
• Sling Psychrometer
• Hygrometer

6
Thermometer

• Used to measure air temperature in degrees
  Fahrenheit or Celsius. Temperature is a measure
  of how much heat energy the air molecules possess

7
Wind Vane

• Measures wind direction
• Tells the direction from which the wind is
  blowing.

8
Wind Sock
Tells the direction the wind is blowing. Used at
airports.
9
Anemometer

• Measures wind speed in miles per hour

10
Barometer

• Measures air pressure in inches of mercury or
  millibars (mb)
• Air molecules push down on objectsincluding
  youwith a force that we call the barometric
  pressure.

11
Rain Gauge

• Measures amount of precipitation in inches or
  centimeters
• Rain is easy to measureall you need is an open
  tube with a rulera RAIN GAUGE.

12
Sling-Psychrometer

• Measures relative humidity using a wet dry
  thermometer.
• Temperature readings are converted by using a
  relative humidity table.

13
Hygrometer

• It too measures humidity.
