4. Wind that blows from land to sea at night.
5. A line on a weather map connecting places with equal air pressure.
6. Water in the form of a gas.
7. A front where cold air moves in under a warm air mass; they pass through quickly and bring thunderstorms, wind and hard rain; the weather turns clear & cooler after it passes.
8. Cumulus clouds that stack on top of one another form these clouds also known as thunderheads. These are the only clouds that develop vertically. They grow to be very tall and can bring thunder, lightening and heavy rain.
10. A dry area on a mountain-side facing away from the direction of the wind. The mountains block the passage of rain, casting a “shadow” of dryness behind them.
12. These are the winds that blow from east to west around the north and south poles (60 N and 60 s to the poles).
14. Wind that blows from sea to land during the day.
15. The amount of water vapor in the air.
17. A front that happens when a warm air mass is caught between two cold air masses and is pushed upwards.
18. Low to mid level clouds that are white and puffy with a flat bottom; usually do not bring precipitation.
20. A belt of winds around earth moving from high pressure zones towards the low pressure at the equator (0 to 30 N and 30 S).

1. What the lower atmosphere is like at any given place and time.
2. The highest type of cloud in the troposphere made up of ice crystals; they look thin and wispy like a feather; do not ever bring precipitation.
3. Winds that blow from the west to the east that are constantly changing and bring stormy weather; these are this winds that bring weather systems across the United States (30 N to 60 N and 30 S to 60 S).
9. A front that happens when a warm air mass and a cold air mass meet, and doesn’t move.
11. A large region of the atmosphere where the air has similar properties throughout with same temperature and humidity.
13. Low level clouds that are gray and blanket-like that usually cover the sky and bring rain showers.
16. A front where warm air moves in over a cold air mass; usually associated with stratus clouds that linger and can bring light rain/snow; weather is warm and clear after is passes.
19. The average weather pattern of a region.
