How global winds affect
weather patterns
Global Winds
- A
current
is a flow of air or water in a
certain direction.
Global Winds
-
Winds move from areas of
high
pressure to
low
pressure.
-
You might expect them to move straight from
the poles (high pressure) to the equator (low
pressure)but…
Global Winds
-The paths of global
winds
curve
because
earth is spinning on an
axis.
- This is called the
Coriolis effect.
Global Winds
-In the northern hemisphere winds traveling north curve
to the
east
.
-Winds traveling south curve to the
west
.
-Weather forecasters use this information to predict
how air masses will move.
-
Polar Easterlies
are winds that
blow from east to west between
60 degrees and 90 degrees
latitude.
-
Prevailing Westerlies
are winds
that blow West to East between
30 degrees and 60 degrees
latitude.
-Trade Winds
are winds that
blow from east to west between
o degrees and 30 degrees
latitude.
-The
doldrums
are the area
directly at the equator where
there is no wind at all.
-The Prevailing Westerlies primarily affect the weather
in the
US
.
-This is why air masses move from
West
to
East
in the US.
Global winds play a crucial role in shaping weather patterns worldwide. These winds flow from areas of high pressure to low pressure, but due to the Coriolis effect caused by the Earth's rotation, they curve in specific directions. The Polar Easterlies, Prevailing Westerlies, and Trade Winds are key global wind systems that impact weather in different regions. In the US, the Prevailing Westerlies are particularly significant in determining the movement of air masses from West to East.

Global Winds - A current is a flow of air or water in a certain direction.
Global Winds - Winds move from areas of high pressure to low pressure. - You might expect them to move straight from the poles (high pressure) to the equator (low pressure)but
Global Winds -The paths of global winds curve because earth is spinning on an axis. - This is called the Coriolis effect.
Global Winds -In the northern hemisphere winds traveling north curve to the east. -Winds traveling south curve to the west. -Weather forecasters use this information to predict how air masses will move.
-Polar Easterlies are winds that blow from east to west between 60 degrees and 90 degrees latitude. -Prevailing Westerlies are winds that blow West to East between 30 degrees and 60 degrees latitude.
-Trade Winds are winds that blow from east to west between o degrees and 30 degrees latitude. -The doldrums are the area directly at the equator where there is no wind at all.
