Air flows in a
clock-wise
direction on
the surface
of the Earth.
Warm, less
dense air
rises forming
clouds
Cold,
dense air
sinks to the
surface of
the Earth.
Airs flows in a
counter clockwise direction
at the surface
of the Earth.

Isobars are lines that connect equal atmospheric
pressure .
The closer the isobars, the stronger the winds blow.
The more spread out the isobars the gentler the winds.
There are many areas of high and low pressure above
the Earth’s surface due to uneven surface heating
creating pressure gradients.
Air moves from high pressure to low pressure forming
winds.
Cold, dense air sinks to the surface of the Earth forming.
Warm, less dense air rises forming clouds

Air flows in a clock-wise direction on the surface of the Earth in
High Pressure areas.
Airs flows in a counter clock-wise direction at the surface of the
Earth in Low Pressure areas.
