Across
  1. 4. Poor Weather Usually brings cloudiness and stormy weather.
  2. 6. formed over large land masses; dry
  3. 8. Fair Weather Generally brings clear skies and calm air or gentle breezes.
  4. 9. Fast flowing, relatively narrow air currents found in the atmosphere around 10 kilometers above the surface of the Earth.
  5. 12. formed over the Arctic; very cold
  6. 13. Forms when a cold air mass pushes under a warm air mass, forcing the warm air to rise. As the front moves through, cool, fair weather is likely to follow. Identified with blue triangles on a weather map.
  7. 15. Forms when a moist, warm air mass slides up and over a cold air mass. This front brings gentle rain or light snow, followed by warmer, milder weather. Identified with red semi-circles on a weather map.
Down
  1. 1. formed within about 30 degrees of the equator; warm or hot
  2. 2. formed over the oceans; moist
  3. 3. Forms when warm and cold air meet and neither air mass has the force to move the other. They remain "standing still." Can bring many days of clouds and precipitation. Identified with both blue triangles and red semi-circles on a weather map.
  4. 5. formed poleward of 60 degrees north and south; cool or cold
  5. 7. out-of-the-ordinary and extreme weather conditions Ex: thunderstorms, tornadoes, hurricanes, blizzards, and floods.
  6. 10. An extremely large body of air whose properties of temperature and humidity are fairly similar and can cover hundreds of thousands of square miles and control the weather for a relatively long time period
  7. 11. Forms when a warm air mass gets caught between two cold air masses and is “cut off”. Can bring strong winds and heavy precipitation. Identified with a purple line with both triangles and semicircles on a weather map.
  8. 14. The transition zone between air masses with distinctly different properties. Can be identified by sharp temperature changes over a relatively short distance, change in moisture content, rapid shifts in wind direction, pressure changes, clouds and precipitation patterns.
