Слайд 1

The United States of America. The Climate.

Слайд 2

The territory of the US is very vast, so It’s more a continent than a country; Lies within 5 climatic zones; Enjoys different types of climate within 1 zone.

Слайд 4

Climate forming factors: The Japan Current (in the Pacific) The Labrador Current (in the Atlantic) The Gulf Stream (originates in the Gulf of Mexico) The Cordilleras

Слайд 5

The Arctic Zone Long cold winters; Short cool summers; Light precipitation. Northern part of Alaska.

Слайд 6

Arctic zone Several countries in the world enjoys arctic climate

Слайд 7

The Subarctic zone Long and cold winters; Short but hot summers; The average January t’ – 25 C; The recorded t’ extreme – 64 C. Central part of Alaska.

Слайд 8

The Temperate zone Abandoned rainfall (2000-2500 mm) Winters – long and cold (average January t’ – 10 C… – 5 C) Southern part of Alaska, northern states of the USA proper adjacent to the Canadian border

Слайд 9

The Subtropical Zone Mild and short winters Average January t’ – 0 C…+ 10 C Rather long summers Average July t’ – from 16 C to 25 C and even higher in different areas

Слайд 10

The Subtropical Zone Interior Plains: The dryness increases from east to west; The tendency – the farther west = the less rainfall; No forests, but prairies.

Слайд 11

The Subtropical Zone The climate of prairies – subtropical continental Hot summers; Comparatively cold winters.

Слайд 12

The Subtropical Zone Variations in climate in prairies has an effect on people’s occupations: Eastern parts – corn belts; Western parts – wheat lands; Farther west – great ranches (cattle and sheep).

Слайд 13

Слайд 14

The Subtropical Zone The Pacific Coast – milder climate than the Atlantic Coast; Warm and dry summers (average July t’ + 16 C); Mild and rainy winters (average January t’ + 8 C) This type of climate is termed as Mediterranean

Слайд 15

The Subtropical Zone Combination of wet winters and dry summers => growing crops. California – the most profitable agricultural industry within the US.

Слайд 16

The Tropical Zone Warm winters; Hot summers. Southern Taxes, southern part of Florida, Hawaii (the Tropic of Cancer)
