  • Weather instruments

    Tools and pieces of equipment used to measure the weather and track data from weather patterns over time
  • Weather instruments used to measure
    • Temperature
    • Precipitation levels
    • Wind direction
    • Wind speed
    • Atmospheric pressure
  • Thermometer

    • Used to measure air temperature
    • Has numbers etched on its side
    • Celsius scale has highest number 100 and lowest 0
  • Temperature is the hotness and coldness of air around us
  • Places near the equator
    Have high temperature because they receive direct rays of the sun
  • Time of the day and time of the year
    Affect the day's temperature
  • When there is no weather disturbance
    Temperature is at its lowest in the morning
  • Temperature is low during rainy days

    And high on a fine weather
  • Barometer

    • Measures atmospheric pressure
    • Helps meteorologists track the weather and predict storms and weather patterns
    • Determines altitude
  • Anemometer

    • Measures wind speed and wind pressure
    • Can measure any other type of gas
    • Has 4 cups mounted on arms attached to a rotating shaft
    • Cups turn faster as wind blows faster
  • Hygrometer

    • Measures the humidity of water vapor in the air
    • Electronic hygrometers take a sample of air and use it to measure the resistance to calculate humidity
  • Rain gauge

    • Measures the amount of rain that has fallen over a specific time period in a specific area
    • A container placed in an open area to collect the rain water
  • Wind vane

    • Shows the direction of the wind at any given time
    • Resembles an arrow with letters indicating north, south, east and west
    • Rotates freely as a result of the wind and points in the direction the wind is coming from
  • Weather balloon

    • Transmits or sends radio signals that give information about the weather
    • Attached to a balloon filled with helium gas and set free into the air
  • Weather instruments are the tools and pieces of equipment that are used to measure the weather and track data from weather patterns over time
