Across
  1. 2. A long-lasting storm that starts over the warm surface of the ocean and has winds of 119 km or higher.
  2. 3. humidity ratio of the amount of water vapor in the air to the actual amount of water vapor needed to reach saturation at a given temperature
  3. 4. The amount of water vapor in the air
  4. 8. A scientist who studies weather and tries to predict it.
  5. 10. clouds Clouds that form in layers. Stratus clouds cover large areas and usually block out the sun.
  6. 11. an instrument that measures atmospheric pressure
  7. 13. A funnel shaped cloud that touches Earth's 3. surface.
  8. 15. rotation of air around a high pressure center in the opposite direction of Earth's rotation
  9. 18. mass a large body of air where temperature and moisture content are constant throughout
  10. 19. Floods Sudden, violent floods that occur shortly after a storm.
  11. 21. An atmospheric condition of high central pressure, with currents flowing outward.
  12. 24. Front When a warm air mass overtakes a cold air mass.
  13. 25. Front When a rapidly moving cold air mass overtakes a slow-moving warm air mass.
  14. 27. Lines on a map joining places with the same temperature.
  15. 28. cloud puffy , white clouds that tend to have flat bottoms, usually indicate fair weather
Down
  1. 1. measuring instrument for measuring temperature
  2. 5. The boundary where unlike air masses meet but do not easily mix.
  3. 6. water that falls from the atmosphere to the Earth as rain,sleet , or snow
  4. 7. Change in state from a gas to a liquid
  5. 9. A violent disturbance in the atmosphere.
  6. 10. Front When a warm air mass and a cold air mass meet and neither can move the other.
  7. 12. a booming or crashing noise caused by air expanding along the path of a bolt of lightning
  8. 14. Front Where a warm air mass is caught between two cooler air masses.
  9. 16. Clouds that form in layers. Stratus clouds cover large areas and usually block out the sun.
  10. 17. Short term fluctuations (days, weeks) in temperature, precipitation, and humidity resulting from rapidly forming and decaying weather systems
  11. 20. the flash of light that accompanies an electric discharge in the atmosphere (or something resembling such a flash) from opposite charges
  12. 21. a gauge for recording the speed and direction of wind
  13. 22. clouds thin, feathery white clouds which format high altitudes
  14. 23. rapid inward circulation of air masses about a low-pressure center
  15. 26. Lines on a map joining places that have the same air pressure.
