Transcript Factors that Affect Climate

Identify six factors
that affect climate
and explain
how each
affects climate.
HIGH LATITUDES
LOW LATITUDES
HIGH LATITUDES
Examples:
LOW LATITUDE
• Miami, Florida
• Dallas, Texas
• Mexico
• Brazil
HIGH LATITUDE
• Detroit, Michigan
• Fargo, North
Dakota
• Canada
• Greenland
How does latitude
affect climate?
increases the average
As latitude ________,
decreases
annual temperature _________.
further you get from the
The _______
colder it gets.
equator, the ________
Page 14 of the ESRTs
We live in the troposphere.
Temperature decreases
with elevation.
During summer, temperature is strongly controlled by altitude -- cold at the
higher reaches of the Alaska and Brooks Ranges, and warmer in the lowlands.
How does altitude
affect climate?
Temperature
increases the average
As altitude _________,
annual temperature __________.
decreases
Altitude
Climate is more MILD
(less fluctuation)
CLOSE to large
body of water.
Climate is more SEVERE
(more fluctuation)
FAR from large
body of water.
How does distance from a large
body of water affect climate?
moderates the temperature.
Water __________
Cooler summers. _______
Warmer winters.
_______
Cities A & B are located
at the same latitude.
City B is closer to a large
body of water.
Its temperature line is
flatter (moderated).
Example:
Westmanna, Iceland
63° N, 20° W
Hebron,
Labrador
58° N, 63° W
How do ocean currents
affect climate?
Warm Currents: warmer climate
Cold Currents: cooler climate
Polar Easterlies
Westerlies
Trade Winds

The Great Lakes
Winds generally blow
from west to east across
the Great Lakes. The
winds pick up moisture
that evaporates from the
lakes. As a result, areas
that are downwind can
receive large amounts
of snow.
What is the name of this
wind belt?
How do prevailing winds
affect climate?
Winds that blow inland from oceans or
water
vapor
large lakes carry more
____________
than winds that blow over land.
The amount of water vapor in the air mass
rain
influences how much ____________
or
snow ____________ will fall.
Most precipitation
occurs on the
WINDWARD side of
the mountain.
Madagascar
Can you tell
which way the
wind blows in
this region?
As the moist air
goes over the
mountain, the
temperature
drops so it
rains.
How do mountains
affect climate?
moist
Windward Side: ___________
dry
Leeward Side: _____________
