29.  In the next slides, look at the color-coded
isotherms (lines of equal temperature).
 What patterns do you notice in the isotherms?
 How do they change from January to July?

33.  Generally, Isotherms run east to west
 Pulled northward in July, southward in
January

34.  Generally, Isotherms run east to west
 Pulled northward in July, southward in January
 Areas covered by glaciers (Antarctica,
Greenland) are cold all year round

35.  Generally, Isotherms run east to west
 Pulled northward in July, southward in January
 Areas covered by glaciers (Antarctica, Greenland)
are cold all year round
 In southern hemisphere, land other
than Antarctica stays warmer in winter
than land in northern hemisphere.
Why?

36.  Generally, Isotherms run east to west
 Pulled northward in July, southward in January
 Areas covered by glaciers (Antarctica, Greenland) are cold all year
round
 In southern hemisphere, land other than Antarctica stays warmer in
winter than land in northern hemisphere. Why?
 Hottest areas in summer are interiors
of continents
 Coldest areas in winter are interiors of
continents

37.  Generally, Isotherms run east to west
 Pulled northward in July, southward in January
 Areas covered by glaciers (Antarctica, Greenland) are cold all year
round
 In southern hemisphere, land other than Antarctica stays warmer in
winter than land in northern hemisphere. Why?
 Hottest areas in summer are interiors of continents
 Coldest areas in winter are interiors of continents
 Locations near the water (especially on
windward side of continents) tend to
be warmer in winter and cooler in
summer
