Climate refers to the overall weatherconditions prevailing in a certain region overa long period of time, which may be in

decades or centuries.

Climate

What is climate?

1

Climate is determined by averaging theweather of a region over a long period of

time, such as 30 years.

Latitude, ameasure of

distance northor south of theequator, affects

climate.

1. Tropical Climate

Kinds of Climate

1

The tropical zonethe region betweenlatitudes 30N and30Sreceive themost solar radiationbecause the sunshines almost directly

over these areas. Dry / sunny or wet /

rainy

Temperate Climate

Kinds of Climate

1

Between the tropicalzones and the polarzones are thetemperate zones.

Temperatures hereare moderate.

Also called

midlatitude climate.

Spring, summer,autumn and winter


6/16

The polar zonesextend from 66.5Nand 66.5S latitudeto the poles. Solar

radiation hits thesezones at a low angle,spreading energy

over a large area.

Polar Climate

Kinds of Climate

1

Polar regions are never warm.


7/16

It takes a lot more heat to increase thetemperature of water than it takes to increase

the temperature of land.

Other Factors

Large Bodies of Water

What is climate?

1

In addition, water must give up more heatthan land does for it to cool.


8/16

Large bodies ofwater can affectthe climate of

coastal areas byabsorbing orgiving off heat.

Other Factors

Large Bodies of Water

What is climate?

1

This causes many coastal regions to be warmerin the winter and cooler in the summer thaninland areas at similar latitude.


9/16

Ocean currents affect coastal climates.

Ocean Currents

What is climate?

1

Warm currents begin near the equator and

flow toward higher latitudes, warming theland regions they pass.

At the samelatitude, theclimate iscolder in themountainsthan at sealevel.

Mountains

What is climate?

1

When radiation from the Sun is absorbed byEarths surface, it heats the land.


11/16

Mountains

What is climate?

1

Heat fromEarth thenwarms theatmosphere.

BecauseEarths

atmosphere

gets thinner at higher altitudes, the air in themountains has fewer molecules to absorb heat.


12/16

Streets, parking lots, andbuildings heat up, in turnheating the air.

Cities

What is climate?

1

Air pollution traps this

heat, creating what isknown as the heat-island effect.

Temperatures in a citycan be 5C higher than insurrounding rural areas.
