Across
  1. 1. Floods Sudden, violent floods that occur shortly after a storm.
  2. 5. mass a large body of air where temperature and moisture content are constant throughout
  3. 9. A scientist who studies weather and tries to predict it.
  4. 11. a booming or crashing noise caused by air expanding along the path of a bolt of lightning
  5. 13. Short term fluctuations (days, weeks) in temperature, precipitation, and humidity resulting from rapidly forming and decaying weather systems
  6. 15. A long-lasting storm that starts over the warm surface of the ocean and has winds of 119 km or higher.
  7. 16. Front When a warm air mass and a cold air mass meet and neither can move the other.
  8. 18. water that falls from the atmosphere to the Earth as rain,sleet , or snow
  9. 19. Lines on a map joining places with the same temperature.
  10. 21. rotation of air around a high pressure center in the opposite direction of Earth's rotation
  11. 23. rapid inward circulation of air masses about a low-pressure center
  12. 25. Clouds that form in layers. Stratus clouds cover large areas and usually block out the sun.
  13. 26. A funnel shaped cloud that touches Earth's 3. surface.
  14. 27. Lines on a map joining places that have the same air pressure.
  15. 29. Front Where a warm air mass is caught between two cooler air masses.
  16. 30. 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
Down
  1. 2. the flash of light that accompanies an electric discharge in the atmosphere (or something resembling such a flash) from opposite charges
  2. 3. clouds Clouds that form in layers. Stratus clouds cover large areas and usually block out the sun.
  3. 4. Front When a warm air mass overtakes a cold air mass.
  4. 6. The boundary where unlike air masses meet but do not easily mix.
  5. 7. Front When a rapidly moving cold air mass overtakes a slow-moving warm air mass.
  6. 8. Change in state from a gas to a liquid
  7. 10. measuring instrument for measuring temperature
  8. 12. clouds thin, feathery white clouds which format high altitudes
  9. 14. an instrument that measures atmospheric pressure
  10. 17. a gauge for recording the speed and direction of wind
  11. 20. An atmospheric condition of high central pressure, with currents flowing outward.
  12. 22. cloud puffy , white clouds that tend to have flat bottoms, usually indicate fair weather
  13. 24. The amount of water vapor in the air
  14. 28. A violent disturbance in the atmosphere.
