Do Now – In BindersDescribe how wind is created.What is the relationship between density and pressure?
What happens to air pressure as I hike up a mountain?
What instrument measures air pressure?
What roles do composition, structure, and properties play in our atmosphere?
Coriolis EffectBecause the Earth rotates, and consists of a
mixture of land and sea, the Coriolis Effect exists
The Coriolis Effect is the movement of particles (such as air) to the right in the Northern Hemisphere
How about the South?They move to the left
Coriolis Effect
Global WindsGlobal wind patterns are caused by:

Wind Moves from HIGH
to LOW
Objects are deflected to
the RIGHT in the
Northern Hemisphere
Remember!Wind gets its name
from thedirection it is blowing
FROM!
Northern Wind PatternsPolar Easterlies
90 – 60 latitude from the eastPrevailing Westerlies
60 – 30 latitude from the westTrade winds
30 – 0 latitude from the East
Latitude NicknamesHorse Latitudes
30 latitudeNamed because the boats stalled and the
horses had to go!Doldrums / Intertropical Convergence Zone
(ITCZ)EquatorTrade winds converge from north and southNamed because boats also got stranded here
Jet StreamsJet Streams form at
latitudes where wind systems come together
High speed westerly winds form high above the surface
