Caused By:
Definition:
The horizontal movement of air
from an area of high pressure
to an area of low pressure.
Differences in air pressure and
an unequal heating of the
atmosphere.
Described by speed and
direction.
Measured with:
Anemometer – wind speed
Wind vane – wind direction
Described by and measured with:
Wind-chill Factor –

Why Does Land Heat Up and
Cool Down Faster?
A solid has molecules that are closer together
than a liquid. This allows for better heat
transfer capabilities. Think of a pool table with
all the balls tightly in a rack. When you hit the
balls with the cue ball, they scatter easily. If
they were not so tightly packed, they would not
scatter as well.
Water has a higher specific heat capacity than
that of land. That means it requires more
energy to heat water to the same temperature
you are heating the land. Water retains heat
more than land which is unable to retain heat
for as long however it absorbs heat well.

Local breezes are winds that blow
short distances
over ____________________.
They are caused by the

Energy from the sun strikes Earth most
directly near the equator. Near the poles, the
same amount of energy is spread out over a

Jet Streams
The jet streams are high-speed (200-400
km/hr) bands of winds occurring at the top
of the troposphere.

Coriolis Effect
The ________Effect
is the name given to the
Coriolis
rotation
concept that the Earth’s ________makes
the winds
________.
curve
It is important in causing the motion of
the global winds. The Coriolis Effect occurs on Earth
and other planets because the planets rotate.

Coriolis Effect
As Earth rotates,
the Coriolis effect
turns winds in the

Hemisphere
toward the right.

Homework” w/s!
Quiz tomorrow on Energy
in Earth’s Atmosphere
Students are divided into teams of four to
five. The first student in each team starts
with a blank piece of paper and writes one
summary sentence, then passes it to the
next teammate. That student adds a
sentence, passes on, etc., until the whole
team has added or until the number of
required sentences is on the paper.
1. Write a riddle describing a concept
learned with wind:
EX:
I spin round and round,
Measuring wind speed, for that I’m proud.
EX:
Be careful not to lose for kite,
For, if you let go, my wind currents will
causes your precious toy to curve to
the right.
