Wind and Weather

3. Humid air masses that form over the ocean
11. The average motion of air molecules
12. Cold air masses that form at high latitudes
14. Seawater pushed toward the shore by winds surrounding a hurricane
15. A measure of the amount of water in the air
16. When warm and cold air masses meet, but neither has enough force to move the other
17. Patterns of wind that span the entire planet
18. Closed loops of air circulation in the troposphere
19. Warm air masses that form at low latitudes

1. Dry air masses that form over land
2. The force exerted by the atmosphere above a given point
4. Thunderstorms that are much larger and longer lasting than ordinary thunderstorms
5. When a cold air mass advances and meets a warm air mass
6. The reason that objects moving in a straight line path seem to drift sideways
7. Atmospheric conditions at a particular time and place
8. A huge volume of air with similar temperature and moisture characteristics throughout
9. A current of fast-moving air in the upper atmosphere
10. When a warm mass of air advances and meets a cold mass of air
13. The movement of air due to differences in pressure
