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
