Global and Local Winds

Global Winds • Global winds show the general direction the air is flowing throughout the globe.

• Refer to your worksheet for these winds

• The winds are named according to where the wind comes from or originates– Ex. What would the name

of this wind be?

Global WindsClimate Zones due to global

winds:• Areas of low pressure are

characterized by rising air, precipitation = Rainforest (0, 60)

• Areas of high pressure are characterized by sinking air, dry air = Deserts (30, 90)

** Add these areas to your worksheet

Continental and Local Winds

• Continental Winds– Monsoon

• Local Winds– Sea breeze– Land breeze– Santa Ana Winds

Monsoon

• A Monsoon is a seasonal change in winds.

• Ex. India, North America

Sea Breeze: Rising Air, Sinking Air, High Pressure, Low Pressure, Dense Air, Less Dense Air, Cloud Formation

Land Breeze: Rising Air, Sinking Air, High Pressure, Low Pressure, Dense Air, Less Dense Air,

Santa Ana Winds• Occur in Southern

California in the late fall/early winter

• A high pressure forms as the desert regions

• As the air sinks it is compressed and usually warms.

Santa Ana Winds

• This creates an offshore wind (blows towards the ocean)

• The air is very dry and often wildfires are a result of this wind
