Across
  1. 4. in a direction opposite to the direction in which the hands of a clock move
  2. 5. a region where the atmospheric pressure at the surface of the planet is greater than its surrounding environment; symbolized by an H on a weather map; generally means nice weather; rotates in a clockwise direction
  3. 6. narrow band of high speed wind high in the atmosphere; moves west to east in the Northern Hemisphere
  4. 7. a blanket of mixed gasses that are held to the Earth by gravity; the most dense gasses are near the surface of the Earth
  5. 11. say or estimate that (a specified thing) will happen in the future or will be a consequence of something
  6. 12. a body of air that has about the same temperature and humidity throughout
  7. 16. come from the land; also known as off-shore winds due to the property of land to lose heat and stay cooler compared to the sea
  8. 17. when temperature differences cause liquids and gases (fluids) to expand and move; the less dense areas continually rise, and the more dense areas continually sink creating a cyclical current
  9. 20. the effect of the Earth’s rotation on the path of air and water; causes the path to curve
  10. 21. a region where the atmospheric pressure at the surface of the planet is less than its surrounding environment; symbolized by an L on a weather map; generally means bad weather; rotates in a counterclockwise direction
  11. 22. a measure of the weight of the atmosphere on a given area of the surface of the Earth; barometric pressure
Down
  1. 1. an area where two air masses with different temperatures and pressures meet
  2. 2. instrument used to measure humidity (moisture) in the air
  3. 3. a tropical cyclone that occurs in the Atlantic Ocean and northeastern Pacific Ocean; low pressure formed over the ocean with warm water that rotates in a counterclockwise direction
  4. 8. rain, snow, sleet, or hail that falls to the ground
  5. 9. a current of air, moving in a particular direction, caused by the pressure differences between surrounding air masses
  6. 10. the leading frontal edge boundary of an advancing air mass that replaces cooler air and has warmer air behind the boundary; indicated on a weather map by a line with red semi-circles
  7. 13. amount of water vapor present in the air; relative humidity
  8. 14. an instrument used to measure wind speed
  9. 15. come from the ocean or other large bodies of water: also called on-shore winds due to the property of water to retain heat and warm up longer compared to the land
  10. 17. the leading frontal edge boundary of an advancing air mass that replaces warmer air and has colder air behind the boundary; indicated on a weather map by a line with blue triangles
  11. 18. motion is one that proceeds in the same direction as a clock's hands: from the top to the right, then down and then to the left, and back up to the top
  12. 19. similar in structure of a hurricane; the only difference is its location; type of disturbance in the Northwest Pacific
