Across
  1. 1. An instrument used to measure temperature
  2. 4. air mass air mass with warm, moist, usually unstable air formed over Gulf of Mexico
  3. 5. Overall weather in an area over a long period of time
  4. 8. An instrument used to measure wind speed
  5. 13. two air masses meet at this boundary. There are four major types ...cold, warm, stationary, & occluded
  6. 14. Evaporation of water from the leaves of a plants & trees
  7. 17. effect A situation in which heat is retained in Earth's atmosphere by mainly carbon dioxide, methane, water vapor
  8. 21. Precipitation that reaches the surface of the earth and does not soak into the soil. It eventually flows to the rivers, lakes, and oceans.
  9. 22. vapor the gas phase of water.
  10. 26. Sun's energy turns Liquid water to gas/water vapor
  11. 29. Any form of water that FALLS from clouds and reaches Earth's surface. ( snow, sleet, hail, rain)
  12. 30. air mass air mass with cold, dry, stable air formed over Canada
  13. 32. humidity % of Moisture (water vapor) in the air
  14. 34. huge circulating air mass (size of several states), max winds 150+mph damaging storm surge,Cat.1-5, forms over ocean/dies over land
  15. 36. A measure of how hot (or cold) something is; specifically, a measure of the motion( kinetic energy )of the molecules in an object.
  16. 37. When a fluid is heated, the warmer part will rise and the cooler portions will sink due to density differences
Down
  1. 1. 0-17 km above Earth's surface, site of weather, organisms, contains most atmospheric water vapor. (temperature decreases with increasing altitude, pressure decreases)
  2. 2. front the boundary of an advancing mass of cold air; often brings thunderstorms with it.
  3. 3. 2nd layer of atmosphere; extends from 10 to 30 miles up; location of ozone layer; absorbs 95% of Ultraviolet radiation; temperature increases with altitude increase.
  4. 4. The layer of Earth's atmosphere immediately above the stratosphere where meteors start to burn up
  5. 6. day-to-day conditions of the atmosphere, including temperature, precipitation, and other factors
  6. 7. Downward sinking movement of water through soil.
  7. 9. front a front where a warm air mass is caught between two colder air masses
  8. 10. preparations knowing what to do in certain natural disasters. ex. have an emergency kit, exit plan, supplies, etc
  9. 11. A rapidly whirling, funnel-shaped cloud that reaches down to touch Earth's surface. Small (can be only 100m wide), max wins 300+mph, fujita F0-F5, forms between cold cP & warm mT fronts in tornado alley
  10. 12. cycle Repeated Movement of water between evaporation, transpiration, condensation, precipitation, infiltration and runoff
  11. 15. the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. It is characterized throughout by an increase in temperature with height.
  12. 16. front A boundary between air masses that don't move possibly causing rain for several days
  13. 18. weather track Our US weather generally moves from west to east
  14. 19. An instrument that measures atmospheric pressure
  15. 20. water that fills the cracks and spaces in underground soil and rock layers
  16. 23. front the boundary of an advancing mass of warm air; usually brings all day showers
  17. 24. how closely packed molecules are in a substance.
  18. 25. air mass warm and dry air formed over Mexico
  19. 27. An instrument used to measure relative humidity
  20. 28. Gas to Liquid; How clouds are formed
  21. 31. pressure A force that is a result of air pushing on an area; it decreases as altitude increases
  22. 33. mass A huge body of air that has similar temperature & humidity throughout
  23. 35. air mass wet, cold air formed over N. Atlantic or N. Pacific oceans
  24. 37. air mass continental arctic air mass with VERY cold, very dry, stable air formed over far Northern Canada
