This document discusses factors that influence worldwide temperature patterns, including latitude, season, time of day, atmospheric conditions, day length, and land versus water. It notes that isotherms generally run east-west and are pulled northward in July and southward in January. Areas covered by glaciers are cold year-round, while southern hemisphere land stays warmer in winter than northern hemisphere land. The hottest areas are continental interiors in summer and the coldest are continental interiors in winter, while coastal areas are warmer in winter and cooler in summer.

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

 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
