What instruments do we use to measure weather

  1. 1. What Instruments Do We Use To Measure Weather?<br />What Are The Instruments Telling Us?<br />
  2. 2. A Thermometer Is Used To Measure the Temperature. <br />Thermometers Indicate How Hot<br />or Cold it is Outside.<br />Some Like it Hot…<br />
  3. 3. A Barometer is Used To Measure Atmospheric Pressure.<br />Atmospheric Pressure is the pressure exerted by the earth's atmosphere at any given point.<br />It is the product of the mass (M) of the atmospheric column of the unit area above the given point and of the gravitational acceleration (G)at the given point.<br />A Barometer indicates whether or not it will rain.<br />SO: (M) X (G) = Atmospheric Pressure<br />Is it Raining Cats or Dogs?<br />
  4. 4. An Anemometer is Used to Measure Wind Speed.<br />Anemometers Indicate How Much Movement of Wind is Present.<br />This Really Blows<br />
  5. 5. A Windsock is Used to Measure Wind Direction.<br />Windsocks Indicate the Direction that Wind Originates From.<br />Which Way Did He GO George?<br />
  6. 6. A Hygrometer is Used to Measure Humidity.<br />Hygrometers Measure the Amount of Water Vapor in the Air.<br />The formula for calculating Humidity is as Follows:<br />The ratio of the amount of water in the air (in grams)(P)/ the amount of water that would saturate the air (in grams) (S).<br />SO:<br />(P)/(S)= Humidity<br />High Humidity Indicates Warmer Temperatures, While Low Humidity Indicates Cooler Temperatures.<br />Warm Moist Air/Cool Dry Air<br />
  7. 7. A Rain-Gauge is Used to Measure the Amount of Precipitation. <br />Rain-Gauges Indicate the Amount of Precipitation that is Released by the Atmosphere. <br />Precipitationoccurs when a local portion of the atmosphere becomes saturated with water vapor and the water condenses. <br />The main forms of precipitation include drizzle, rain, sleet, snow, and hail.<br />Have you ever seen the Rain?<br />
  8. 8. A Cloud Mirror is Used to Measure the Percentage of Cloud Cover.<br />A Cloud Mirror Estimates the Amount of Cloud Coverage in the Sky.<br />The percentage of cloud cover is visually estimated and expressed in oktas (eighths of the sky covered in clouds).<br />What do you call a sheep with no legs? <br />
