Climate

© 2015 Pearson Education, Inc.

Climate

• Several influencing factors:– Clearly defined changes in seasonal temperatures– Prevailing wind direction is west to east.– North–south mountain ranges in the west modify air masses as they

move east.– Atmosphere takes on the more extreme heating and cooling

characteristics of land than water.• Winters are cold.• Summers are hot.

– Gulf of Mexico—Important source of moisture for the Gulf Coast and Interior Lowlands

• Characteristics:– Humid subtropics– Dry subtropics– Marine west coast – Western steppes and deserts– Humid continental – Subarctic and polar climates

© 2015 Pearson Education, Inc.

Humid Subtropics

• Hot and sticky• Eastern Texas and Oklahoma east to

Florida and Virginia and sections of West Virginia

• The climate in many of these states is subject to extremes.

© 2015 Pearson Education, Inc.

Dry Subtropics (Mediterranean)

• Pacific Coast• San Diego to San Francisco

– Summers relatively cool (time of drought)– Winters relatively warm

• Precipitation low, but clearly defined wet and dry seasons

• Lack of snow

© 2015 Pearson Education, Inc.

Marine West Coast

• Northern CA to Alaska• Winter—Warmer due to moderating effects

of ocean• Summer—Cool• Cascade mountains produce a moderating

effect.

© 2015 Pearson Education, Inc.

Western Steppes and Deserts

• Eastern OR and WA south to Colorado Plateau• East of Rocky Mountains—Corresponds roughly

to the Great Plains• Semiarid climate• Temperatures tend toward extremes• True deserts of North America concentrated in

the southwest:– Southern TX– Southern AZ– Southern CA

© 2015 Pearson Education, Inc.

Humid Continental

• Northern part of United States into southern Canada

• Humidity• Winter—Cool to cold• Summer—Can be very hot• Home to America’s agricultural heartland

– Corn Belt– Dairy Belt

© 2015 Pearson Education, Inc.

Subarctic and Polar

• Subarctic– Wide swath of central Canada and Alaska– Precipitation levels low—Mostly as summer rain

• Polar• Northern edges of Canada and Alaska

– Freezing conditions most of the year– Some days without sunlight

© 2015 Pearson Education, Inc.

Environmental Challenges

• Continental climates have always experienced environmental extremes.

• Water issues in dry conditions cause issues.

• Northeastern and midwestern locales may experience too much water.

• Storms, especially in the southeast, may cause dramatic problems.

Historical Settlement

• European core has influenced the early settlement of both countries.• Core influences:

– New England—MA, RI, and CT• Originally a destination for religious freedom• Artisanal work and shipbuilding

– Southern Atlantic—VA and southward• Cultivation of subtropical crops—notably tobacco• Plantation system a major aspect of work by smaller farms

– Middle Atlantic—NY, PA, and parts of NJ and MD• English, Dutch, Scots–Irish, and Swedish influences• Mixed agricultural system• Manufacture of tools, guns, and wagons• Iron ore work in PA• Influential impact of American middle west and parts of Appalachians

– French Canada—Quebec; St. Lawrence River area• Early settlers were French; British took over in 1763.• Some farming along St. Lawrence River• French Canadian population has remained contextual; little spatial diffusion.

Western Expansion

• Historical view was that all land on the continent is to be civilized by Americans

• Expansion of United States– Louisiana Purchase—1803– East Florida—1819– West Florida—1810–1813– Texas—Annexed in 1845– Mexican Cession—1848– Oregon County—1848– Gadsden Purchase—1853

Population

• U.S. population growth after 1800– High birthrates (fertility

rates)– Low death rates (mortality

rates)– Immigration

• Canadian population growth– Grew mainly by natural increase between 1867 and 1900– But limited by a low fertility rate

• Population distribution– Predominantly east of the Mississippi River– Greatest concentration in northeast quadrants

• Population of Canada– Most people live 200 miles of U.S. border

• Highly urbanized by beginning of 21st century• Globalization transforming cities

– Transportation• Expressways• Automobiles

• Spatial expansion• Megalopolis

– Result of congestion and sprawl– “A very large city”– More government—More demands

• Canadian Cities– More acceptance of government planning– More compact; higher densities– More emphasis on public transportation

Summary of Chapter

• The United States and Canada occupy one of the largest land masses in the world, and one with a wide array of environments.

• Both countries evolved out of a spatial integration process in which frontiers were pushed back by advancing populations. The result is a racial and cultural mosaic that enriches their contemporary geographies, while presenting challenges to governments that struggle to accommodate competing groups.

• Each country is an economic powerhouse that occupies a prominent position in the world economy.

• Progress has come with costs in terms of environmental degradation, global warming, employment insecurity among North American workers, increased reliance on foreign sources for important natural resources, and a growing fear that economic progress may not be sustainable.
