Two-Column Notes
Name
Topic: A2.2 The atmosphere has wind patterns.
Period
Uneven heating causes air to

move (A47).
Date
_______
Weather is the __________________ of Earth’s atmosphere at
a particular ______________ and _________________.

_______________ is a very important part of weather.

Wind is air that moves _____________________, or parallel to
the ________________________.

Uneven ____________________ of Earth’s surface causes
such pressure differences, which set air in ________________.
How wind forms (A48)

Sunlight is concentrated _____________ the equator because it
strikes the surface _______________.

Sunlight is more _______________ out near the poles because
it ____________ at a ______________ angle.

The warm air _________________, and an area of low
_______________ forms.

The cooler, _________________ air ___________slowly, and
an area of ____________ pressure forms

Air moves as ________________ across the surface, from
______________ pressure to _________________ pressure.

When the difference in _____________________ between two
areas is small, the wind may move ________ ______________
to be noticeable.

A very large __________________ difference can produce
wind _____________ enough to uproot trees.

Global Winds (A48)

Global winds travel _______________ of km in
___________ ________________.

Uneven heating between the ____________________ and
_______________ ___________________ causes global
winds.
Earth’s rotation affects wind
direction (A49)

If Earth did not _______________, global winds would
flow directly from the _____________ to the
_____________.
A 2.2 The atmosphere has wind patterns

Earth’s rotation __________________ the direction of
winds and other objects moving _____________ the Earth.
Earth’s rotation affects wind

direction (A49)
The influence of Earth’s rotation on free moving objects is
called the ___________________ __________________.

In the N. Hemisphere, winds curve to the
__________________ in the direction of the motion.

Winds in the S. Hemisphere curve to the
_______________.

Because the Coriolis Effect causes _______________
winds to ______________, they cannot flow directly from
poles to the equator. Instead, global winds ______________
along __________ routes in each ____________________.
Global Wind Belts (A50-51):
Trade winds:

Blow from the _____________, moving from the horse
latitudes ___________the ____________. (0o to 30o N & S
of equator).
Westerlies:

Blow from the _____________, moving from the horse
latitudes _____________ the _____________. (30o to 60o
N. & S. of equator)

They bring ____________ across much of the
_____________ ______________.
Easterlies:

Blow from the ______________, moving from the
_____________ regions toward the mid- _____________
(60o to 90o N. & S. of equator)
Jet Streams flow near the top of

the troposphere (A52)
Jet streams usually flow in the ________________ troposphere
from ___________ to ____________for thousands of
kilometers.

Each hemisphere has ________ jet streams, a ____________
jet stream and a __________________ jet stream.

The polar jet stream has a _______________ influence on
weather in _________________ America.

Scientists must know ________________ the jet stream is
flowing to make _________________ weather predictions.
