Meteorologists

  1. 1. How Meteorologists predict the weather<br />
  2. 2. Air Masses and Fronts<br />Air Mass: a large body of air that has about the same temperature and humidity throughout<br />It can be warm or cold<br />Can have a little or lot of water vapor<br />
  3. 3. Air Masses Continued…<br />Usually move west to east in the United States<br />
  4. 4. Air Masses do not mix together!<br />The line where two air masses meet is called a front.<br />
  5. 5. Cold Front<br />When a cold front moves and collides with a warm front, the warm air rises quickly and cools rapidly, causing huge storm clouds to build up.<br />Rain or snow may fall.<br />Thunder and lightning may also occur.<br />Cold Fronts move quickly, so the storm may not last very long.<br />
  6. 6. Warm Front<br />When a warm front collides with a cold front, the warm air slides slowly upward over the cold air mas. <br />As the warm air rises, it cools and forms clouds.<br />Clouds are feathery and form high. Thicker clouds that form lower n the sky follow.<br />A gentle rain or snow is produced.<br />When the warm front passes, warm, mild weather follows.<br />
  7. 7. Tracking and Predicting Weather<br />Forecast: prediction of what the weather will be like for the next few days.<br />Meteorologist: Person who studies the weather<br />
  8. 8. What Meteorologists Track<br />High and Low Temperatures<br />Humidity<br />Air Pressure<br />Precipitation<br />Air Masses<br />Fronts<br />Wind Speed and Direction<br />
  9. 9. How They Track<br />Computer-generated maps<br />Radar Image Maps<br />
  10. 10. National Weather Service<br />A government agency that collects information about weather.<br />Use advanced tools, such as satellites above the earth to collect information from all over the world<br />
