Wind and Water

Local Winds...

• •blow over short distance

• •created by unequal heating

• •occur within a small area

• •land and sea breezes

• All of these

Global Winds...

• •blow steadily over long distance

• •created by unequal heating

• •occur over large area

• •global wind belts

• All of these

Due to the Coriolis Effect

• Northern hemisphere global winds curve to the right and southern hemisphere global winds curve to the left.

• Northern hemisphere global winds curve to the left and southern hemisphere global winds curve to the right.

• Northern hemisphere global winds Don't Curve and southern hemisphere global winds curve to the left.

• Northern hemisphere global winds curve to the left and southern hemisphere global winds don't curve.

Trade winds

• – steady winds that flow from east to west between 30ᵒN latitude and 30ᵒS latitude

• cold winds that blow from east to west near the North and South poles

• steady winds from west to east between latitude lines 30ᵒN and 60ᵒN and 30ᵒS and 60ᵒS

• high winds near top of troposphere generally flowing west to east and are able to influence the weather

Polar easterlies

• – steady winds that flow from east to west between 30ᵒN latitude and 30ᵒS latitude

• cold winds that blow from east to west near the North and South poles

• steady winds from west to east between latitude lines 30ᵒN and 60ᵒN and 30ᵒS and 60ᵒS

• high winds near top of troposphere generally flowing west to east and are able to influence the weather

Prevailing westerlies

• – steady winds that flow from east to west between 30ᵒN latitude and 30ᵒS latitude

• cold winds that blow from east to west near the North and South poles

• steady winds from west to east between latitude lines 30ᵒN and 60ᵒN and 30ᵒS and 60ᵒS

• high winds near top of troposphere generally flowing west to east and are able to influence the weather

Jet streams

• – steady winds that flow from east to west between 30ᵒN latitude and 30ᵒS latitude

• cold winds that blow from east to west near the North and South poles

• steady winds from west to east between latitude lines 30ᵒN and 60ᵒN and 30ᵒS and 60ᵒS

• high winds near top of troposphere generally flowing west to east and are able to influence the weather
