Across
- 4. in a direction opposite to the direction in which the hands of a clock move
- 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
- 6. narrow band of high speed wind high in the atmosphere; moves west to east in the Northern Hemisphere
- 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
- 11. say or estimate that (a specified thing) will happen in the future or will be a consequence of something
- 12. a body of air that has about the same temperature and humidity throughout
- 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
- 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
- 20. the effect of the Earth’s rotation on the path of air and water; causes the path to curve
- 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
- 22. a measure of the weight of the atmosphere on a given area of the surface of the Earth; barometric pressure
Down
- 1. an area where two air masses with different temperatures and pressures meet
- 2. instrument used to measure humidity (moisture) in the air
- 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
- 8. rain, snow, sleet, or hail that falls to the ground
- 9. a current of air, moving in a particular direction, caused by the pressure differences between surrounding air masses
- 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
- 13. amount of water vapor present in the air; relative humidity
- 14. an instrument used to measure wind speed
- 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
- 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
- 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
- 19. similar in structure of a hurricane; the only difference is its location; type of disturbance in the Northwest Pacific
