Wind

Wind

Why is there wind?

• Differences in air pressure

• Differences in air temperature (UNEVEN HEATING

Multiple Choice

What direction does wind move?

• From high pressure to low pressure

• From low pressure to high pressure

• Whatever direction is going to mess up my hair the most

Open Ended

Why is there wind?

Wind Direction

• Air moves away from high pressure areas

• Air moves toward low pressure areas

Multiple Select

Which are true?

• Cold air has higher pressure

• Cold air has lower pressure

• Cold air is more dense

• Cold air is less dense

Air Pressure 

• Cold air has more pressure

• Cold air is more dense and has more molecules. It will sink.

• Warm air has less pressure

• Warm air is less dense and has less molecules. It will rise.

• High to Low is the only way to go!  (air moves from high pressure to low pressure)

Multiple Choice

Why do winds curve?

• Uneven heating

• The earth rotates

• Weather

Coriolis Effect

• Why do global winds curve?

• The Earth rotates

• Think about what you saw happen with the balloon.

Multiple Select

Which are true

• Land warms faster

• Land cools faster

• Water warms faster

• Water cools faster

Land always wins

• Land warms up faster than water

• Land cools off faster than water

• Temperature differences make pressure differences and wind

Sea Breezes

• Warm air rises from the land

• As it goes over the water it cools and sinks

• The colder air over the sea moves toward the land

Daytime: Sea Breeze

• Land is warmer and has low pressure

• Water is colder and has high pressure

• Air moves from high pressure to low pressure

• Wind moves from Sea to Land

Multiple Choice

In the daytime, the high pressure is over the...

• land

• sea

Land Breezes

• Warm air rises from over the water

• As it goes over the land it cools and sinks

• The colder air over the land moves toward the sea

Nighttime: Land Breeze

• The land cooled faster than the sea

• The land is cooler and has higher pressure

• The sea is warmer and has less pressure

• Wind flows from high pressure of the land to the low pressure over the water

Multiple Choice

At night the high pressure is over the ...

• sea

• land

Easterlies

• Air at the poles is cold

• Cold air has high pressure

• The air moves away from high pressure areas

• The air moves from east to west

Multiple Choice

Easterlies are found

• Near the poles

• At the equator

• Between 30-60 degrees

Westerlies

• Move from west to east

• Found between 30-60 degrees

• Affects the US - carries moist air and produces rain and snow

Trade Winds

• Air moves toward the Equator

• Air moves from east to west

Multiple Choice

For trade winds, the air moves ...

• towards the equator

• away from the equator
