Across
- 4. represented by alternating blue and red lines with blue triangles pointing towards the warmer air and red semicircles pointing towards the colder air.
- 9. is represented by a solid line with semicircles pointing towards the colder air and in the direction of movement.
- 10. take shape in high-latitude regions and are cold.
- 11. form in the Arctic region and are very cold.
- 12. has similar characteristics to a polar maritime air mass , but because of the shorter sea track the air is colder and less moist.
Down
- 1. a weather front formed during the process of cyclogenesis, when a cold front overtakes a warm front
- 2. is marked with the symbol of a blue line of triangle-shaped
- 3. are cold, dry, and stable. These air masses originate over northern Canada and Alaska as a result of radiational cooling
- 5. are cool, moist, and unstable.
- 6. originate over the warm waters of the tropics and Gulf of Mexico, where heat and moisture are transferred to the overlying air from the waters below.
- 7. form in low-latitude areas and are moderately warm.
- 8. is a body of air with a relatively constant temperature and moisture content over a significant altitude.
