7yr 09 #17 Weather Map Tools

  1. 2. Scientists and weather forecasters use weather maps to help them see weather patterns.
  2. 3. They place symbols on the maps to help them see what is going on with the weather in various parts of the country.
  3. 4. Weather Maps: Doppler Radar Maps
  4. 5. Weather Maps: Pressure & Temperature
  5. 6. A Cold Front symbol shows the edge of a mass of cool air.
  6. 7. A Warm Front symbol shows the edge of a warmer air mass.
  7. 8. A Stationary Front means neither the warm air or the cool air are moving very much.
  8. 9. How many fronts can you identify on this map?
  9. 10. A large “H” means an area of higher pressure. Higher pressure usually means nice, clear weather. H
  10. 11. Which state has high pressure?
  11. 12. A large “L” means an area of lower pressure. Lower pressure usually means clouds, rain, or snow. L
  12. 13. How many “Lows” are on this map?
  13. 14. What are they? What do they do?
  14. 15. <ul><li>Thermometer </li></ul><ul><li>Wind Vane </li></ul><ul><li>Anemometer </li></ul><ul><li>Barometer </li></ul><ul><li>Rain Gauge </li></ul>
  15. 16. <ul><li>A thermometer is </li></ul><ul><li>a weather tool used to measure the temperature. </li></ul>
  16. 17. <ul><li>By observing wind vanes, we can know the direction of the wind. Knowing the direction of the wind is an important part in predicting the weather. </li></ul>
  17. 18. <ul><li>Wind speed is an important part of weather. </li></ul><ul><li>An anemometer is a weather tool that measures wind speed. </li></ul>
  18. 19. <ul><li>Barometers are important to measuring air pressure. Air pressure can help you predict good or bad weather. </li></ul>
  19. 20. <ul><li>A rain gauge is a weather tool used to collect rain. </li></ul><ul><li>Using measurements on the side of the rain gauge, you can see how many inches it rained. </li></ul>
